reader comments: homeopathy

It is shocking there are a class of people in this world (including Rationalists) who look down upon Homeopathy as just pseudo-science. They also believe that homeopathy patients get well due only to the Placebo effect.

Truth to tell this anti-Homeopathy mentality has been raised to the level of SUPERSTITION. And it is all too obvious. I wonder whether these jokers have ever treated themselves using Homeopathy. Because have you ever heard of the saying: “The taste of the pudding lies in its eating”? What’d you say to a person who without first tasting it goes about passing disparaging remarks about the pudding? I’d say s/he is a CRACKPOT!

reply: And what do you say to a person who would not jump out of an airplane without a parachute because some theoretical physicist told him what would happen when he hit the ground going 200 mph? I'd say he was pretty wise to admit that the laws of physics are going to apply to him whether he believes in them or not. There are many people who believe that wearing a tinfoil hat will protect them from evil rays being aimed at them to control their minds. Try it, I'm sure you'll soon realize they are right. In the meantime, you might want to do some study on the many cognitive biases that lead us into self-delusion about such things as homeopathy. You might also get a better understanding of what is called the placebo effect. We don't mean that it's all in your head or that believing something works makes it work when we call homeopathy (acupuncture and all forms of energy medicine) placebo medicine. We mean that your illness ran its course but you gave credit to your pseudoscience. We mean that your stress level was reduced and your body resolved your illness or you felt less anxiety about your illness. Your stress level can be reduced by giving you confidence in our ability to heal you; we do this with theatrics, dress, room decoration....yes we're not much different that the fortune teller with her fancy headdress and crystal ball or the shaman with his feathers and medicine bag. We are able to make you feel better by relaxing you and our awareness of the power of suggestion. You want to believe in our ability to heal you so much that you will believe just about any nonsense we throw your way. Shamans knew of our tricks thousands of years ago. Mesmer made an art of it. It may be true, as Santayana, noted that "Those who cannot remember the past are condemned to repeat it." But it is also true that those who remember the past shall benefit by exploiting it. Hypnotists and energy healers have learned the latter lesson well. Patients like you are probably in a third camp: those who are ignorant of the past and don't have a clue.

Coming back to Homeopathy, in case you did not know let me inform you that it is the most widely used Alternative Medicine in the world.

reply: So? Lots of things are popular but wrong.

From the poor to the rich everyone have had their physical and mental ailments cured through Homeopathy. Governments around the world endorse it.

reply: Believing won't make it so and coming with a government seal of approval is not as meaningful as being supported by the vast majority of scientists. Margaret Chan, M.D., head of the WHO, promotes acupuncture, as does the WHO itself. So? This is not a good thing but a bad thing. Josephine Briggs is head of the NIH's division that promotes energy quackery of all sorts. So? That's not a good thing but a bad thing.

FYKI, chronic diseases can only be cured through Homeo and by using Allopathy.

reply: Nonsense.

But we’ve a bunch of CRACKPOTS who’ve made it their mission to denounce Homeo as nothing but placebo and also pass disparaging comments against it. The tenacity of the anti-Homeo attitude very well matches (both in intent and psyche) the ones we usually find in religious fundamentalists.

reply: Well, at least you don't compare us to Nazis or rapists. Anyway, we need all the tenacity we can muster up to deal with the ignorant fanatics that keep springing up like mushrooms in a dark cave.

So what if you theoretically find Homeo to be strange? So what if you are bemused/amused by how it actually works? But why should that PREVENT YOU FROM TRYING OUT HOMEO? After all as a patient why should it matter how it works (and, that too, without any side-effects) as long as it works? Do you feel if you do that it will be an insult to your long-held (but irrational) anti-Homeo ideology? Do you feel you will not be able to look at your own face in the mirror when you go back home? And do you really want me to believe that all the patients who’ve been cured through Homeopathy in the last 200 years is only because of the Placebo effect? What an insult to ones intelligence! This is a deliberate propaganda spread by the anti-Homeo brigade in order to cover-up their own fallacious and false outlook.

Raz

reply: I feel exactly the same way about Prince Charles and all other defenders of homeopathy. Science insults their belief in magic and superstition. They've been duped for so long that they can't look in the mirror and admit it. It is an insult to anyone's intelligence to believe that succussed and diluted water can cure cancer or mitigate the sting of a flea bite. The best bit of propaganda I've seen in many years is this notion of the 'memory of water.' Talk about a whopper!

Enjoy your delusions and when you need real medicine don't go to a quack.

Hi Robert.
I find that when I do a search for homeopathic articles your site opens itself.

reply: That's great news!

Obviously you want people to read your article, so I read it and wanted to offer some feedback. And I don't do soundbites.

reply: Uh O. I feel a criticism coming on.

If I didn't know what I know about homeopathy, not only that it works but how it works, I would probably come to precisely the conclusions that you have. It has become very clear to me that the issue with homeopathy is not the lack of evidence. The issue has to do with how people think of science. You state that there is only one kind of science, done well or badly. This is simply not true. Anyone who has ever done any study of science itself, not just a given methodology or technology, knows this. What is good science is actually very controversial, not just in terms of methodology or interpretation of results or the type of analysis used, which are controversial things themselves, but more importantly is the paradigm that is assumed. It appears that you subscribe to the mechanistic materialism or reductionist paradigm.

reply: True enough.

This is not the only one and it is highly debatable that this is the most appropriate form of science to study living things, including healing and disease in humans. A better alternative, arguably, is the science of complex, self-organising systems. This is not very well-known in medicine. It requires the study of living systems as wholes, and seeks to understand unpredictable self-creative features of these systems. For example, what is the placebo effect? It amazes me that the placebo effect is such an important concept even in reductionism, and yet it is only described, not explained. To say that something is placebo effect does not explain anything. To understand something like that means to understand how living systems can heal themselves with minimal input from any physical "curative" substance, with no more than a belief for example. And how they heal themselves in unpredictable and sometimes surprising ways.

reply: The materialistic mechanistic paradigm is one that seems pretty explanatory to me regarding healing spontaneously, by suggestion, by conditioning, by expectation, and with the help of ritual theater (what many people call 'placebo healing'). These are all testable concepts, and they've been tested many times under rigorous conditions. The main question now isn't whether there is placebo healing but whether it is ethical to knowingly use it.

This evidence speaks strongly for a different approach in medical science, one which can explain not just spontaneous placebo effect but also how other non-intrusive non-mechanistic practices like homeopathy can actually work to support a living system to heal itself. And the experimental method of trying to isolate causes and effects just is not up to the task. Here are some important concepts to look up if you want to be truly sceptical and look at the evidence in an unbiased way before making up your mind! Autopoesis. Biosemiotics. Far from equilibrium systems. Negentropy. Hierarchical ordering. Chaos theory. I've been studying these concepts for 15 years and writing a phd on this subject; it is certainly not just obfuscating it is as scientifically and philosophically as rigorous as I can get.

reply: I believe you. I also think you are engaging in special pleading: claiming that homeopathy can't be subjected to scientific testing unless we change the definition of science to fit your paradigm and relate homeopathic elixers to such concepts as autopoesis, biosemiotics, negentropy, chaos theory, and hierarchical ordering.

And regarding the memory of water. One very simple thing that debunkers like yourself don't ever seem to grasp about this is that homeopaths have always said that the energy that water is exposed to is very important. Remedies are made using distilled water. The heat energy used in distilling has perhaps disrupted or denatured the "memory" (I prefer information) of anything previously in the water. And the remedy needs to be kept away from other sources of energy, especially sunlight.

reply: I'll keep that in mind.

Regards
Dr Emma Aiken
feel free to post any of this, as long as you refrain from anything personally derogatory or re-edit my text. Thanks.

reply: I've asked Dr. Aiken for some info about her doctorate and her university. If she replies, I'll post this info for those who might be interested in pursuing these topics in more depth.

Dr. Aiken has informed me that her current doctorate is in psychology, earned at Swinburne University of Technology in Melbourne, Australia. She adds:

I taught 3rd year level statistics and part of my job was to explain that statistical analysis makes all kinds of assumptions about what data is useful, how to manipulate it and what the results represent, and these assumptions are controversial. Obviously I am more familiar with behavioural science, and many would say it isn't a "real" science, but that highlights the inadequacies of mechanistic science to grapple with living unpredictable systems, including scientists themselves! Any student of philosophy at any mainstream university is going to come across Thomas Kuhn's 1962 book "the structure of scientific revolutions" which discusses the nature of science as a social construct which reflects assumptions about reality and is subject to change as those assumptions are challenged. Of course most students are more interested in understanding what they have to [know] in order to pass their subjects, they don't want to be taught something and then be told that what they've been taught is not completely clear cut and reliable.

My current phd (An ecological model of medicine) is being supervised by Michael Dix and Arran Gare, neither of whom are linked in any way to homeopathy. Arran is the head of the philosophy department and is an internationally respected philosopher of complex processes and author of several books on the subject. Both he and Michael have several articles published in the ejournal Journal of Cosmos and History which you can freely access.

As for spooky elements like action at a distance etc this is an example of the incoherence and fragmentary nature of the dominant scientific model. Medical doctors have no need for, and generally no great knowledge of, these kinds of concepts. The world described by quantum physics doesn't translate to our experience of reality as we assume it to be. A good argument that our assumptions are fundamentally faulty. Otherwise we would have to conclude that science is inherently incoherent. I suggest Ilya Prigogine and Francisco Varela as the best sources to begin your research.

best regards,
Emma

reply: As a student of philosophy, I did study Kuhn's The Structure of Scientific Revolutions. Whatever merits the book has, it spawned an industry of nonsensical writing about "paradigm changes." Kuhn may have been right about how some areas of some sciences progress, but I think he was dead wrong about the most important idea in the history of science: natural selection and the evolution of species. There was no anomaly that couldn't be explained by traditional biology that natural selection could. There was no puzzle to be solved that Darwin and Alfred Russel Wallace offered the solution to. Natural selection certainly requires a paradigm shift from Biblical creationism, but not according to the structure that Kuhn lays out for all science.

I also don't think Kuhn offered a defense of the notion that science is nothing but a social construct. That idea may be popular in some philosophical circles, but it has little bearing on how actual scientists do science.

Also, everybody doing philosophy of science before and since Kuhn knows that science makes assumptions about reality. That fact doesn't give philosophers or scientists a free ticket to make up anything they want. There's a reason scientific ideas need to be put to the test of experiments, not that experiments prove that the assumptions they're based on are absolute or are reflections of 'the way things truly are,' whatever that might mean.

In short, just because there are difficulties in explaining some things using a mechanistic model rather than a teleological or ecological model doesn't mean the latter two are either more accurate views of how things 'really work' or that they provide more fecund explanations of the world we perceive. Whatever else one might believe about science or philosophy, the freedom to make up facts and call them assumptions on par with the assumptions science makes about the external world and our epistemological relationship with it, is not a belief I would ever subscribe to.

10 April 2015
Dr. Carroll, I'll leave the philosophy to you, but I'd like to spend a moment taking apart the following paragraph by Dr. Aiken:

As for spooky elements like action at a distance etc this is an example of the incoherence and fragmentary nature of the dominant scientific model. Medical doctors have no need for, and generally no great knowledge of, these kinds of concepts. The world described by quantum physics doesn't translate to our experience of reality as we assume it to be. A good argument that our assumptions are fundamentally faulty. Otherwise we would have to conclude that science is inherently incoherent. I suggest Ilya Prigogine and Francisco Varela as the best sources to begin your research.

This paragraph is a great example of how sloppy writing leads to sloppy thinking, which leads to grave misunderstandings about our present state of knowledge and our capacity for acquiring further knowledge. While the following critique may not have anything to do with homeopathy directly, it is precisely Dr. Aiken's sort of confusion that leads people of intellectual competence to lend credence to physical impossibilities (or extraordinary improbabilities). Her reference to "action at a distance" is not, I take it, meant to identify quantum entanglement specifically. Rather, it's meant to illustrate the very real fact that there are observable physical phenomena which cannot be attributed to a classical or intuitive mechanism. What we have come to call quantum entanglement is predicted by applying the concepts of conserved quantities (such as spin) and wave function collapse. It is, indeed, "spooky" (that's an Einstein quote). But it happens (it has an effect, and can be observed). As stated, it is a mathematically predictable phenomenon which occurs just as predictably in the laboratory. The fact that our present understanding of the phenomenon implies certain things which contradict our classical/intuitive sense of the universe does not invalidate that sense; it merely illustrates its limitations. Now, the "dominant scientific model" to which she refers can only be an epistemological entity (that is, the scientific method). The irony is that rather than being "fragmentary" or "incoherent" (is this a subconscious/Freudian reference to quantum coherence?), the fact that this model lead us to the knowledge of and the capacity for modeling mathematically -- to great precision -- such counterintuitive phenomena as quantum entanglement demonstrates its incredible versatility. Think about that: by applying consistently the principles of science and empiricism, we have developed an entire body of knowledge of enormous explanatory power despite its apparent (not to be confused with "actual") incompatibility with our experience of the macroscopic world.

That last sentence brings me to another point, which is her claim that "the world described by quantum physics doesn't translate to our experience of reality as we assume it to be" and that, therefore, "our assumptions are fundamentally faulty." This is absolutely preposterous. Firstly, it is not clear if she is speaking in an epistemological sense or a scientific one -- is she saying that our (scientific) assumption of locality is false, or the (epistemological) assumption that we can obtain knowledge of the universe through empiricism is false? In any case, the fact is that quantum mechanics is the most successful theory of physics ever developed and it predicts, to extraordinary degrees of accuracy, an extremely wide range of phenomena. Furthermore, we understand its limitations -- it cannot make accurate predictions in the presence of strong gravitational effects. But the point here is that the "world described by quantum physics" is exactly the world in which we live, and its predictions about the behavior of macroscopic objects are perfectly consistent with our daily experience. It just also happens to predict certain other things, generally on a microscopic scale, which are not intuitive. Therefore, the strongest indictment I could possibly support against our "assumptions" of the macroscopic world is that they are inadequate for the purpose of predicting quantum phenomena; to call them "fundamentally faulty" is gratuitous epistemic nihilism.

So what does all this have to do with homeopathy? The paragraph I critiqued above is not quite quantum woo; it's actually worse. It's got just enough seriousness in it that it gets the attention of intelligent folks, but its vagueness requires that the reader have a contextual understanding of its meaning. In this case, it serves to undermine science by equating our (scientific but inadequate) assumptions of the physical world with our (epistemological) assumption that knowledge can be obtained via empiricism. It is a veiled "bait and switch." By calling into question our basic epistemic assumptions, she calls into question the body of knowledge from which we conclude that homeopathy has no mechanism (and since we know that it has no effect, the logical conclusion is that it does not exist, rather than that our requirement of a mechanism is misguided).

I do not think Dr. Aiken wrote this disingenuously; I think she believes these things sincerely, to the extent that such poorly defined notions can be believed at all. I hope that this helps illustrate the sort of confusion that causes people of apparent intelligence such as Dr. Aiken to misunderstand the physical world and our role in it, as well as our capacity for understanding it.

Regards,
Joshua Warren

reply (by Bob Carroll): I think Dr. Aiken's point was that quantum physics isn't used in medicine or biology and that that shows that quantum physics doesn't apply to all reality. I think she's wrong in her inference. The fact that we don't use quantum physics to balance our check books doesn't imply that a new paradigm of reality is needed to explain accounting. I might also note that some parapsychologists, such as Dean Radin, believe that quantum physics does apply to biological systems and he cites several people who try to explain apparent paranormal phenomena with concepts from quantum physics.

If in your not so humble opinion homeopathy is a duff protocol can you explain how the veterinary clinics in NZ that use homeopathy have such a high success rate.

reply: I probably can, but you probably wouldn't believe me. Let's start with your claim that veterinary clinics in NZ that use homeopathy have "a high success rate." What does it mean for a vet to have a high success rate? What counts as a success in veterinary medicine and who keeps score? Your request for an explanation of something so unclear is unreasonable.

There is no placebo effect with animals.

reply: Yes there is. The main placebo effect with animals is called classical conditioning. Another is the expectation effect. You remember Pavlov's dogs: he rang the bell when he fed them and he conditioned them to salivate by just ringing the bell, without presenting them with food. Other studies have found that the rituals and practices (like getting jabbed with a needle in a clinical setting) can condition both humans and animals to have physical responses, especially of the opioid system. Humans and other animals can be conditioned to release chemical substances such as endorphins, catecholamines, cortisol, and adrenaline. It is not strictly true that animals have no expectations in treatment. None of us do if it is the first time we are being treated, but dogs, horses, and humans do expect effects from treatments. Shots of morphine will make a dog salivate. Any shots, even of saline solution, after that will make the dog salivate. Of course, the animals may not be aware of their expectation, but conditioning studies show conclusively that the bodies of animals do respond in expectation of results. Also, some animals are misdiagnosed and what looks like a successful cure isn't a cure at all. And, sometimes an animal heals not because of the vet's treatment but because nature is just taking its natural course.

Perhaps you think the placebo effect involves a treatment working only because the patient believes the treatment will work. If so, you have a naive understanding of the placebo effect. I'd suggest you read my not-so-humble entry on the placebo effect, but you'd probably ignore me.

I note that your site that posts so many rebarbative negative comments which never start with “ I have carried out test and research on @@@@@ and the results of this testing and research show that etc etc etc “ Surely to be fair one has to do one’s own research rather than repeat comments by people who have an agenda. I must point out that I am not a registered homeopath so no agenda here.
Alastair

reply: You're right. I am not a scientific researcher, but I learned how to read in school and have found that there is more than one way to gain knowledge of a subject. You are wrong in assuming one must do one's own research in order to be fair. Your comment implies that some researchers have an agenda, which is true. Our job as seekers of knowledge is to evaluate the quality of other's research and try to avoid as much as possible accepting only research that is biased in our favor.

I have addressed the belief that animals are not susceptible to the placebo effect before. Click here for my comments on horses treated with reiki (a type of energy medicine).

By the way, Alastair, do you think one must jump out of an airplane without a parachute before one can speak intelligently about the likely consequences of doing so? Must I shoot up with heroin before ?... well you get the point ... anyway, not all research involves first-hand lab work. Some research involves reading and analyzing what others have done.

Alastair replied and said he was too busy doing research in his lab to continue the conversation. He's in his 80s, he says. Maybe he'll discover a homeopathic cure for AIDS.

I am an expert on homeopathy.  Your article has some correct information but the conclusions are based entirely on emotional feelings.  One needs to look at real data.  I offered to one of the quack busters a few years ago to debate a good study openly online, but he disappeared.  This tells me his whole campaign was deceptive.  I offer the same to you.

This is my experience w/ “Dr” Barrett: http://bookonhealing.com/education/quack-busters.html

If you are open to a proper scientific discourse while putting emotional conclusions aside, let me know.

Jacob Mirman, MD

reply: You make me sound like some southern governor who tried to help a woman keep her marriage together only to fall in love with her. Do my conclusions really seem to you to be "based entirely on emotional feelings"? I'm ready to engage in discourse, but I suspect anything I say will appear "emotional" to you because you may be one of those bright fellows who thinks a conclusion is based either on evidence or emotion. Those conclusions that you agree with are based on evidence and the ones you reject are therefore based on emotions.

Anyway, if you promise to provide specific criticisms of my arguments in our discourse and refrain from simply accusing me of being emotional, I'm willing to accept your proposal....with one condition: you can choose the scientific study we discuss, but it must be a large-scale, randomized, controlled study done within the last 10 years. I don't want to deal with small studies, studies that aren't randomized, or those that don't use control groups. Nor do I want to deal with some study done 50 years ago, where the documentation might be too scanty to allow for proper evaluation of the study's methodology and protocols.

To help you understand what kind of control group I require, I have posted a chapter from a book I am writing for you to read. I try to explain where I went wrong in my critiques of acupuncture, homeopathy, and other so-called "alternative" medical treatments.

I assume you have read enough of my work to know that I agree that homeopathy works as well as any other placebo treatment. Any meaningful controlled study will have to be able to tease out effects from the homeopathic medicine from those due to (a short list of) placebo and non-placebo effects.

I hope you have read Bausell's book Snake Oil Science or my review of the book. I think he has done a great service in clarifying how medical treatment is much more than the pill we take for specific problems. We still have a long way to go toward understanding how inert substances or magical rituals can affect healing.

I look forward to an intellectually challenging and fruitful discourse.

Dr. Mirman replies:

I like it.

Take a look at this study: http://www.flusolution.net/bjcp.pdf

Read the Lancet editorial about it: http://bookonhealing.com/appendix.html

Jacob

reply: For those who are following this discussion, the study Dr. Mirman cites was published in the British Journal of Clinical Pharmacology in 1989:  "A Controlled Evaluation of Homeopathic Preparation in the Treatment of Influenza-like Syndromes" by J. P. Ferley et al. Even though I made a condition of engaging in this discourse that the study be no more than ten years old, I'll let this requirement pass for reasons that will become apparent.

Below is Bob Carroll's evaluation of Ferley's paper:

In the introduction to the study, the authors note that there are two schools of thought about testing homeopathic potions. One school thinks that homeopathy can't be tested by randomized, double-blind, control group studies because each treatment is adapted to the specific conditions of the patient and no two patients are alike. Obviously, the authors belong to the other school, which holds that some homeopathic medicines treat symptoms, and they can be tested just like any other medicine that treats symptoms.

I thank Dr. Mirman for selecting a short article to discuss (only 7 pages long).

I was impressed that the article was published in the British Journal of Clinical Pharmacology, even though I had never heard of that journal before now. Anything with "British Journal" in it sounds authoritative to me. I realize that my being impressed by this is rather childish. Anyway, I discovered that the BJCP is the sister journal of the British Journal of Pharmacology. Both journals are published by the British Pharmacological Society. So far, so good.

I must admit that the title of the article did not go down well, however, because it specifies that the focus of the research was on treating "influenza-like syndromes." Such a focus could be an open door to vagueness in evaluation criteria. However, I was pleased to discover that the study would focus on at least one objectively measurable symptom: rectal temperature. A reading of 39 °C (101 °F) was required to be admitted into the study and 37.5 °C (99.5 °F) was required to be labeled "recovered."

Except for the first measurement of rectal temperature, which was done in a clinical setting, the researchers allowed the subjects to do their own testing and recording. They were instructed to do so each morning and evening. Likewise for the five doses of "medicine" each was given. The "active drug" and the placebo were similar in appearance and were administered sublingually. Again, the first dose was taken in the clinic, while the rest were self-administered each morning and evening. The reliability of the compliance and measurements could be called into question. I understand, however, that having a subject come in twice a day to have someone put a thermometer up his butt is likely to discourage all but the most devoted advocates of scientific testing of hypotheses from participating, unless they were paid handsomely to do so. Most researchers don't have vast sums of money to give to volunteers, so relying on the subjects to do as instructed is somewhat of a necessity in these kinds of trials. I also understand that no study is perfect and that being overly demanding regarding measurements and the collection of data would be unfair. Even so, these problems shouldn't be ignored, especially if the results indicate a very non-robust conclusion. In such cases, just a few participants in either group going the other way might evaporate any statistical significance measured.

I am assuming that the authors are using 'syndromes' synonymously with 'symptoms.' In the U.S., we use 'syndrome' to mean a set of symptoms.

Many people don't know whether they have the flu, a cold, a sinus infection, or hay fever because some of the symptoms are the same. The researchers followed reasonable protocols to ensure that their subjects had the flu and not something else. The other evaluative criteria used to determine eligibility for the study were subjective. One list of symptoms was designated "the five cardinal symptoms": headache, stiffness, lumbar pain [backache], articular pain [aching joints], and shivers. They also collected data on cough, fatigue, and coryza. (I have to admit, I had to look up the last symptom. According to Wikipedia, coryza refers to "the inflammation of the mucus membranes lining the nasal cavity which usually gives rise to the symptoms of nasal congestion and loss of smell, among other symptoms." Stuffy nose is how we describe it in California.) In any case, the researchers focused on fever (as measured by rectal temperature) and the five cardinal symptoms, which, in my experience are more likely to be found with flu than with, say, a cold. To be eligible, a patient had to have two of the five cardinal symptoms at the time of visiting the clinic for the first time. To be declared "recovered," none of the five cardinal symptoms could be present.

We know from experience, of course, that in the case of a mild flu most patients should recover on their own in about a week no matter what drugs they take or even if they don't take any medicine. Of course, some people recover more quickly than others. Generally speaking, young healthy folks will recover more quickly than old feeble folks. Thus, for such a study where it is known both that the illness usually resolves itself in a week to ten days and its duration is likely to be significantly affected by age, general health, and severity of the illness, special care must be taken in the randomization process that determines which group each subject is assigned to.

The researchers addressed the problem of studying something that naturally resolves itself rather quickly by requiring that to be admitted a patient had to have manifested his symptoms within 24 hours of coming to the clinic for the first time and "recovery" would be measured 48 hours after admission.

The researchers addressed the problems of age, general health, and severity of illness at admission in several ways. For example, anyone who had had a flu shot or was under treatment for an immune disorder was ineligible. The researchers used 30-years-old as the dividing line between young and old. (A minimum age of 12 was used as an eligibility requirement.) An initial rectal temperature greater than 39 °C and having at least three of the cardinal symptoms meant one had a "severe" case of the flu; otherwise, one had a mild to moderate case.

Part of their data analysis included looking at how those in each group were divided up during the randomization process according to age, sex, temperature at admission, and severity of illness at admission. (Two other items were included in this analysis, but I'm not sure I understand them. One involved when the participants were included during the flu season and the other involved a delay of less than 12 hours before inclusion.)

The number of eligible cases in the "active drug" group is listed at 237, but the number of males in that group is listed at 93 and the number of females at 127 (total=220, not 237). The number of males and females in the placebo group adds up to 226, but 241 is given as the number in the group. The average temperature (in °C) at intake for the "active drug" group was 38.9, while it was 38.8 for the placebo group, so the groups were nearly identical in terms of degree of fever. The groups were also nearly identical in terms of severity of illness. Average age was 33.7 in the "active drug" group and 35.1 in the placebo group.

General practitioners in the Rhône-Alpes region in France, most of whom were not homeopaths, recruited patients who presented themselves with flu-like symptoms during the 1986-1987 flu season. The participants were assigned to the "active drug" or placebo group by a randomized, double-blind method. Each participating physician was given enough coded boxes of "medicine" to treat four to six patients. Only after the data was collected were the codes unblinded.

No mention is made of what instructions the physicians were given regarding how to go about recruiting patients to enroll in the study or what to say when they administered the dose. We don't even know if the subjects knew they might be getting a homeopathic treatment. What they were told could have affected how they reacted. Were they all given the same information? We don't know.

As noted above, no study is perfect, but if I were to do a follow-up study I would instruct the physicians who do the recruiting to try to recruit an equal number of men and women. I would have coded one of the substances with even numbers and one with odd numbers, and asked the physicians to try to give half of each type to those under 30 and half to those over thirty. Before analyzing the data and before unblinding all the data, I would determine that there was not an overload of old or young people in either group. If there were, I would disqualify some of them from the study to make sure that I wasn't measuring the effect of age on the outcome. After I was confident that age was not going to be an artifact I would be measuring, I would unblind all the data. (I would make every effort to make sure I was not biased in my selection of those to be disqualified because of age.)

In the study, 237 received Oscillococcinum (oscillo), a homeopathic product from Boiron Laboratories in France. (Yes, this is the same company that supported Jacques Benveniste.) The product is made from a combination of wild duck heart and duck liver. It sells for about the price of a flu shot and is a $15 million-a-year business in the U.S., but is much more popular in Europe.* The active ingredients listed on the packaging of oscillo are written in Latin and mean extract of the liver and heart of a Barbary duck: Anas Barbariae Hepatis et Cordis Extractum. It is diluted one part in a hundred 200 times, which means there are no duck molecules left in the final product. Bob Park calculates that the last duck molecule is vanquished after about 12 dilutions. If  the entire universe consisted of nothing but oscillo, there would be no molecules of the stuff left after about 40C.* Or something like that. You get the picture. One duck could produce enough oscillo to supply everyone on earth and all their offspring for millions of years with a lifetime supply. Please, no quack jokes, but now you understand why I put "active drug" in scare quotes.

I know that most skeptics stop right here and say that homeopathic potions can't work because there's nothing in them. (Bob Park, for example, simply asserts that no homeopathic remedy has ever passed the test of a randomized, placebo-controlled, double-blind trial. Park doesn't examine any studies, though he did try for five years to get Jacques Benveniste to collaborate with him on a simple test.*) I'm not going to stop here, however. I'm going to look at the study and examine the methods, protocols, size of samples, use of controls, randomization, clear and specific starting points and ending points, justification of conclusions, and the like. I'm not going to worry about the fact that there's no active ingredient in the homeopathic potion we are testing.

But first, a little history.

The word Oscillococcinum was coined in 1925 by the French physician Joseph Roy (1891-1978) who said he had observed an oscillating bacterium in the blood of flu victims. He searched for the bacterium in several animals until he found it on the liver of a duckling.*  (Dr. Mirman supplies more information below as to why the innards of ducks might be a good place to develop an anti-flu potion: migrating ducks are natural reservoirs of influenza viruses.) Okay. That's enough history.

Bob Park has a chapter in Superstition: Belief in the Age of Science called "The Barbary Duck," in which he discusses this very popular potion sold worldwide as something that will relieve influenza-like symptoms. (For those who are into diluted details, consider the following: "In some regions the name Barbary Duck is used for domesticated and "Muscovy Duck" for wild birds; in other places "Barbary Duck" refers specifically to the dressed carcass, while "Muscovy Duck" applies to living C. moschata, regardless of whether they are wild or domesticated. In general, "Barbary Duck" is the usual term for C. moschata in a culinary context.) You can buy this product  in America off the shelf. It is not regulated by the FDA. In fact, no homeopathic remedy is regulated by the FDA because the 1938 Food, Drug, and Cosmetics Act specifically excludes most homeopathic potions from FDA oversight. note

In the Ferley study, there were 478 participants, this study is certainly large enough. Nine participants were excluded because they did not meet the eligibility criteria: 5 from the homeopathic group and 4 from the placebo group. Why they were admitted in the first place isn't discussed.

As noted above, the study used a rectal temperature of 39 °C (101 °F) to be eligible and 37.5 °C (99.5 °F) as an objective measurement of recovery. According to Wikipedia:

Although the value 37.0 °C (98.6 °F) is the commonly accepted average core body temperature, the value of 36.8 °C ±0.7 °C, or 98.2 °F ±1.3 °F is an average oral (mouth under the tongue) measurement. Rectal measurements ... are typically slightly higher....

Body temperature normally fluctuates over the day, with the lowest levels around 4 a.m. and the highest in the late afternoon, between 4:00 and 6:00 p.m. (assuming the person sleeps at night and stays awake during the day). Therefore, an oral temperature of 37.2 °C (99.0 °F) would, strictly speaking, be normal in the afternoon but not in the morning. An individual's body temperature typically changes by about 0.5 °C (0.9 °F) between its highest and lowest points each day.

Thus, some might quibble about the use of temperature to determine eligibility and recovery. The participants would have visited the clinic for the first time at various times during the day, but ideally they should all have had their readings at the same time of day. Likewise for the readings they did at home in the morning and evening. Depending on what time of the morning or evening, temperatures could fluctuate and skew the outcome. It seems that if temperature typically changes by about 0.5 °C between its high and low points each day, some participants might be designated as recovered and some as not recovered because of the time of day they took their temperatures. It might be more appropriate to use a range of temperatures as indicating recovered: for example, say, 37.25 °C to 37.75 °C (99.05 °F to 99.95 °F). In my view, however, I think that with the size of these samples, it is likely that any bias in the groups due to variations in temperatures during the day would cancel each other out.

So, what did the research show?

The data show that the vast majority of participants (86.4%) did not recover in 48 hours. In the oscillo group, there were 39 (17.1%) recoveries and in the placebo group there were 24 (10.3%).

Not surprisingly, the researchers found that younger people and those with less severe symptoms recovered more quickly than older people or those with severe symptoms. Two unusual stats stand out, however. The number of recoveries among those under 30 was three times higher in the oscillo group (21 to 6) and the number of recoveries in the mild-to-moderate severity group was twice as high in the oscillo group (31 to 16). Such differences are not likely due to chance. There was no significant difference in the two over-30 groups.

There was almost no difference in the numbers in each of the 12-29 age groups that had not recovered within 48 hours. Sixty-three of the oscillo group were still sick after 48 hours, while 68 of the placebo group hadn't recovered yet. For some reason, the numbers don't add up in the chart provided by the authors for recovery according to age and treatment group. The number in the oscillo group has dropped to 207 and the number in the placebo group has dropped to 205. The authors note that there was a mild flu that season and don't indicate that anyone in the study died, but the data for 21 in the oscillo group and 29 in the placebo group are missing.

The researchers established to their satisfaction that even though the participants weren't supervised during the study, neither group was taking more antibiotics or cold medicines. They did find that the control group took more drugs for pain and fever (50.2% to 40.7%).

Finally, 61.1% of the oscillo group thought the treatment worked, while 49.3% of those taking a placebo thought it was effective. It is not specified by the authors, but it seems reasonable to assume that the participants gave this assessment after the study had concluded. The patients were asked to keep records for one week. Most flu symptoms during a mild flu will last about a week, so the felt recovery may have had nothing to do with actual effectiveness. Anyway, finding out that more than 60% of a group felt a medicine was effective sounds impressive until you find out that 50% who are given a placebo agree with them. Subjective measurements are interesting, of course, but they don't tell us anything about the effectiveness of the medicine. At least in my book, patient satisfaction is not equivalent to drug efficacy.

A statistical formula shows that the odds of the 6.8% difference in recovery being due to chance are 3 in 100. However, if about 1.7 percent of those given oscillo went the other way and didn't recover, and about 1.7 percent more of those given the placebo had recovered, we wouldn't be evaluating this study. All it would take would be a different outcome for 3 or 4 in each group to make it obvious that nothing unusual is going on here. For example, if the number of recoveries in the oscillo group had been 35 instead of 39, and the number of recoveries in the placebo group had been 28 instead of 24, the percentage difference between the two groups would drop to 3.4% (15.4% and 12%, respectively), a difference you might expect between any two groups of several hundred people with flu symptoms, both of which were given placebos.

The authors conclude their summary of the study by commenting: "The result cannot be explained given our present state of knowledge, but it calls for further rigorously designed clinical studies." I'm surprised that a peer-reviewed journal would allow such a statement to preface a published study. (The statement is repeated near the end of the paper.) Since this is a study on a homeopathic potion, it is likely that this claim will be understood to mean that we found the potion works significantly better than a placebo, but we have no way of explaining how any homeopathic remedy works. The claim is ambiguous enough, however, to mean (if one is generous in interpretation) that the study found that the homeopathic potion got better results than a placebo and the authors can't come up with an explanation for the data in terms of our present state of knowledge regarding causal mechanisms and studies. But they don't have to. All they have to say is that this difference could be a statistical fluke and more studies should resolve the issue.

Making sure everybody takes their rectal readings at the same times each day and night might yield slightly different results. Controlling for age before final analysis of the data might yield slightly different results.

So, the next question is: have all the studies done in the twenty years since this one was published helped to resolve the issue?

Not really.

Why?

Because there haven't been any follow-up studies. Twenty years have gone by and not a single attempt at replication of this study has been published. The authors admit that the difference they found between the two groups was "modest." They certainly did not find evidence of a robust effect from the homeopathic brew. What they found, they said, was "interesting." Maybe so, but why has nobody done a follow-up? One would think that at least one study would have been done on young people with mild flu symptoms, since the differences in those groups were the greatest of those measured in the study.

The authors recognize that the differences measured, while statistically significant, are not sufficient to establish a causal relationship between oscillo and recovering from the flu. They note that "it would be unwise to claim that the study has demonstrated a cause and effect relationship between the drug and the recoveries." Yet, in the very next sentence they write: "The positive effect of the homeopathic preparation cannot be explained in our present state of knowledge...." As they themselves note, they didn't establish a causal relationship between oscillo and recovery from the flu. They didn't prove effectiveness. They found a statistically significant difference between two groups. More studies might provide strong scientific evidence that oscillo causes some reduction of some flu-like symptoms in some people.  Even so, if more studies replicate this one, the effect of the oscillo is so small as to be of little medical value. Would you buy a remedy that brags about being 10% more effective than a placebo or helps some people some of the time or helps with flu symptoms in 2 out of 10 cases?

It has been over 20 years since this study was published and nobody replicated it.

Why?

Note: This claim needs some clarification. As Dr. Steven Novella writes: "Homeopathic remedies are classified as “drugs” by the FDA, which means they fall under FDA oversight, but at the same time they are granted automatic approval as long as they appear in the Homeopathic Pharmacopeia. What this means is that the Homeopathic Pharmacopoeia Convention of the United States, the non-governmental agency that writes the homeopathic pharmacopoeia, only has to add an agent to their list and it is granted automatic FDA approval....But because homeopathic remedies do fall under FDA regulation the FDA has the power to decide that a product poses a safety risk to the public and therefore can demand evidence for safety."

If you followed the link from the picture of the oscillo box above, you will find that the ad on Amazon states that the product is  "Regulated as a drug by the FDA." This is very misleading because the only way a homeopathic drug can be banned by the FDA is if it shown to be harmful in itself, which is impossible since there are no active ingredients in the products. (This is also misleading and confusing because of complex homeopathy and the fact that there are products on the market with active ingredients that are labeled homeopathic.)

If you gave five unlabeled homeopathic drugs in look-alike vials of liquid to a team of homeopaths and asked them to identify what each vial contains, they couldn't do it because they have nothing to look for to distinguish one drug from another. I venture that you could mislabel every drug in a homeopath's pharmacy and get the same level of satisfaction from both homeopath and patient.

One of the most hilarious press releases I've ever read came from the French equivalent of the FDA announcing a recall of two homeopathic drugs because they had been mislabeled. The agency said: "...this mix-up does not pose any particular risk . . .” No kidding.

Dr. Mirman's reply:

I just reviewed your review of the Ferley study. I definitely agree that the study should be replicated. In fact, I am aware of two similar studies. Both are published in homeopathic press, therefore by your standard they are not admissible here. One of them is actually in French, so I can’t even read it. It is very hard to get a conventional journal to publish a homeopathic study.

BC's reply: Two attempts at replication in twenty years? It may be hard to get a homeopathic study published, but it shouldn't be that hard to do the studies.

Nonetheless, we are discussing a specific study, so let’s stick to that. As you mentioned, some aspects of its design could be improved, as the authors themselves mentioned in the study. However, the study overall is good quality, and was even praised by an editorial in Lancet (http://bookonhealing.com/appendix.html).

BC's reply: As you know, I didn't reject the study because of design flaws. (And you know that it doesn't matter who else has praised it or criticized it. This is our review.)

First we need to set the goal for this discussion.

BC's reply: I took your challenge to discuss "a good [homeopathic] study" to be the goal.

In my understanding, we are working with a hypothesis that submolecular (dilution beyond Avogadro’s number) homeopathic preparations are not different from placebo. This is your assertion. Mine is the opposite: I believe they are different from placebo in biological systems (humans and animals) when properly applied. By the latter I mean the said system must in theory be susceptible to the effect of the particular preparation we are studying (i.e. if we are studying flu, the preparation must have something to do with the flu). We are in absolute agreement that these preparations contain no active molecules. There is no point in belaboring this point any further. My assertion is that there is something else in the preparation, something other than molecules, that exerts the effect, and we have no understanding of what it is. You, of course, believe that there is nothing there and we can’t expect to see any effect. Therefore, there is only one question: is there effect or not? Is the effect statistically significant as accepted by the research community, that is p<0.05. It is entirely immaterial how we feel about it. I agree that expecting any effect when looking at the issue from the confines of the science of today is completely ridiculous. Yet, first we need to look and see what is, whether it makes sense or not, then and only then attempt to explain what we see.

BC's reply: I think I stated it very clearly in my response that I would evaluate the study on the basis of the data, i.e., any statistically significant differences between the experimental and control groups.

Now back to the study at hand. The remedy being studied is Oscilococcinum 200C, a submolecular preparation of gizzards of migrating ducks.

It is well known that migrating ducks are natural reservoirs of influenza viruses. They are the main cause of spread of new strains of influenza throughout the world every year. Oscilococcinum is a homeopathic remedy made from duck tissues, presumably containing a multitude of influenza viruses. Therefore it could in theory be used as a treatment for disease these viruses are able to produce. This remedy should have the capacity to trigger in the Vital Force some form of recognition of the energetic essence of the disease causing agent and help it deal with it more effectively. (I know you laugh at this “energy talk”, but, unfortunately, I don’t know a better language to express these concepts). This remedy should in theory be most effective for those people, who are suffering from some virus they have not previously been exposed to, because for them this “energetic” information is most useful. People who have been already exposed to all the viruses, whose signatures are contained in the remedy, would not derive much benefit from the remedy, if we follow this theory.

BC's reply: The above paragraph has nothing to do with the study. As you say, let's stick to the study.

In my opinion, this is the reason why Oscilococcinum worked so much better for the young people than for those older. The older people have already been exposed to the viral signatures in the remedy sometime during their longer life, so the remedy did not provide their Vital Force with any useful information. As you noticed in the study, the difference of response of younger people to the active preparation vs. placebo was 25% vs. 8.1%, p<0.01. There was no statistical significance in the response of older people. This accounts for the overall smaller difference, even though still statistically significant. This pattern of response fits with the explanation given above, although, of course, does not prove it. Regardless of whether you accept the explanation, the fact of this statistical significant response is evident. The bottom line is, this puts the hypothesis of equality of Oscilococcinum 200c (a submolecular preparation) and placebo in doubt.

BC's reply: Your opinion is not in line with the data. The data show that the number of recoveries among those under 30 was three times higher in the oscillo group (21 to 6) and the number of recoveries in the mild-to-moderate severity group was twice as high in the oscillo group (31 to 16). Such differences are not likely due to chance. But this is insufficient data from which to conclude that Oscilococcinum was the cause of these differences. It is because there could be a variety of factors that might account for the data that further studies are absolutely necessary before any talk of having established causality is considered. An interesting correlation was found, but you are jumping the gun by offering an explanation for a causal event that might not even be happening.

So now the ball is back in your court. Do you agree that this particular study, even given its minimal shortcomings,

1. is good enough 2. puts your point of view in doubt?

If yes, we can go further. I would agree that one study does not prove anything. I would be happy to discuss other studies in this manner. If not, please explain point by point.

BC's reply: The authors of the study write: "it would be unwise to claim that the study has demonstrated a cause and effect relationship between the drug and the recoveries." The study is certainly not good enough to assert that Oscilococcinum is a significant causal factor in the reduction of flu symptoms. The study has not changed my view about there not being compelling evidence of the causal efficacy of any homeopathic remedy.

I assume you selected this study because it was the best one you could come up with or you think it is typical of very good studies. This surprises me because the study is so old and insignificant. I have tried to provide you with a thorough evaluation of the study, indicating why the statistical significance found does not prove even a small effect from Oscilococcinum.

I read on your website how two experiences convinced you of homeopathy's powers despite the obvious absurdity of its fundamental claims. You write in "My Conversion": "I was certain that anyone who practices something so ridiculous must be a complete idiot or a crook.... The whole concept sounded so improbable, it fired up my curiosity. I knew I’d have to investigate it further, if only to disprove it." Then you provide two anecdotes involving your grandmother and your father. Rather than seek alternative explanations for these experiences, you sought further confirmation of homeopathy. You have done this for many years, you say. I doubt there is anything I could say that will change your mind at this point. I don't expect to change your mind and I hope you don't expect to change mine. I engaged in this discussion because I want to keep an open mind that maybe there is compelling evidence for a belief I reject. I must say that the evidence you provided is very weak and indicative of your low standards of evidence. I think you are deluded and are deceiving yourself about homeopathy. Belief in vitalism is magical thinking and a throwback to nineteenth century superstitions.

By the way, as an aside. Your use of the word POTION is intriguing. While the quack buster community dislikes homeopaths because they feel that we are basically using placebo and deceiving people, there is a different community that dislikes us for completely opposite reasons. Super-fundamentalist Christians have seen how much we can accomplish with our remedies, they understand that this can’t be explained by science of today, so they are afraid that we are practicing some kind of witchcraft and are in league with the devil. So to them our remedies are real magical POTIONS! I’d love to have a three-way discussion between you, me and them!

BC's reply: Not gonna happen.

Another aside and a correction: Homeopathic remedies are in fact regulated by the FDA and are classified as FDA-approved drugs. This allows me, as an MD, to prescribe them and expect the nurses in the hospital to administer them. I have done it! Funny, isn’t it?

BC's reply: I don't think it's funny at all. I think it's pathetic.

As I note above, the FDA must approve any drug listed in the Homeopathic Pharmacopeia. Nobody needs to prescribe such things as Oscilococcinum. You can buy it off the shelf in most drug stores where it is probably placed next to a dozen other ineffective potions (as it is in my local Rite Aid).

Jacob Mirman, M.D. replies:

It is true, we won’t change each other’s minds.

However, it is interesting, how you are presented with a study with high p value and just discount it as unimportant, just because you can’t explain the mechanism of action. Of course, there are other studies we could discuss, but they will have the same problem: high p value but no explanation for mechanism of action, so you are likely to discount those as well, without any explanation. P value defines significance, by definition, yet you say it is insignificant. There is nothing else that would prove significance to you, if you don’t accept the definitions universally accepted in scientific community. Anyway, I make my attempts at showing people what is, but they see what they choose, each according to their own preexisting convictions and/or “party affiliations”. To some, my work is so effective it must be from the devil. To others, it is not effective at all. Both are quite religious in their convictions.

"...a scientist must ...be absolutely like a child. If he sees a thing, he must say that he sees it, whether it was what he thought he was going to see or not. See first, think later, then test. But always see first, otherwise you will only see what you are expecting. Most scientists forget that." (Douglas Adams So Long and Thanks for All the Fish)

Are you a scientist?

Jacob

reply: I'm not a scientist, but I know how to read a scientific study. I don't discount high p values, but I recognize that statistical significance does not mean "important" and "unimportant" does not mean "statistically insignificant." You are willing to assign a causal factor that needs an explanation for a mechanism of action on the basis of the p value found in one study. You even speculate as to what that mechanism is, even though it involves introducing the concept of "vital energy," something the scientific community rejected long ago.

You are both misleading and wrong when you say "P value defines significance, by definition, yet you say it is insignificant. There is nothing else that would prove significance to you, if you don’t accept the definitions universally accepted in scientific community."

I don't say that P value is insignificant. You seem to think that statistical significance implies importance and causality. Statistical significance means that the statistic is not likely due to chance. It doesn't mean that a causal event has been demonstrated, much less that anything significant or important has been discovered. Shall I repeat that? Statistical significance does not mean causal efficacy. If you don't know that, then you should not be trying to pass yourself off as a scientist. Your ignorance is appalling. You have the gall to claim that I "don’t accept the definitions universally accepted in scientific community," when you don't even understand what statistical significance means in science. If you understood what statistical significance means you would have understood the significance of my noting that "All it would take would be a different outcome for 3 or 4 in each group to make it obvious that nothing unusual is going on here." Statistical significance in conjunction with a very large study and a very large effect size backed by several replications can usually be taken to indicate that a causal connection has been established. But statistical significance by itself should never be taken to prove causality. Correlation does not prove causation. Even if a causal connection is probable, statistics can never tell you what mechanism is at work. If you took the time to read the book chapter I recommended, you would know that in addition to your speculative cause of some mystical effect involving a vital force, there are many other possible explanations for the effect (if it is an effect). I've reproduced the list of possible causes in a recent newsletter. You can look at by clicking here.

Finally, you're wrong when you claim that nothing would prove significance, in the sense of causal efficacy, of a homeopathic drug. All I require are some follow-up studies that meet the conditions I've already stated.
