Ayurveda rant

For quite some time, I haven't really been in such a position as to worry about Ayurvedic bunkum within my own circle of contacts. Sure, I have a lot of elders in my family who believe in it, but many of them still put more stock in actual medicine, and if the two paths created conflicting outcomes, more often than not, they would trust real doctors first. I had to deal with it very little growing up because as traditional as many people were who surrounded me, I was also directly surrounded by math, engineering, and science books... along with a good amount of material on music as well, though that's a bit unrelated to the topic. Although we didn't have much to count as for medical material, or even very much of anything about biology in particular, there was still enough of a scientific mentality to account for some element of reason even among those who were otherwise die-hard nuts for alternative treatments. Now, I might have been a little bit sheltered from that having parents who stood quite a distance from the lunacy, but that enabled me as a child to study Ayurveda from a third-person perspective.

What I found, more or less, was that it was complete and utter garbage of the highest order. There was nothing in there based on any sort of real substantial basis. Almost all of it is based on tradition and word-of-mouth, and it's organized into this bizarre vitalistic view of health, in much the same way as homeopathy is (though I wouldn't even know the term homeopathy until much later in life). Now it is true that because of my outright absolute disdain for tradition as a vehicle for creating merit, I did take the extreme position that there could be nothing of value in Ayurveda. But then, I was 7 years old at the time I arrived at that conclusion, so it isn't entirely unexpected that I would do something that off-the-mark. I've since at least accepted that Ayurveda has probably amassed enough ideas about remedies that some of them are valid, and at least a few have actually gone through solid testing by real doctors in recent years. Nonetheless, the foundational principles of Ayurvedic medicine are still garbage, and the notions it has about how or why anything works are demonstrably wrong.

A large part of the market for Ayurveda here in the U.S. is not really the practice of what pretends to be medicine, but generally more therapeutic services like massages and spa treatments. While this is still steeped heavily in a large sea of nonsensical babble in the same way that almost all so-called spa "treatments" and concepts are, at least nobody views these practices as vital facets of our continued well-being in the same way that something labeled "medicine" would be. Massages and oil rubs and so on are viewed as luxury services and we tend to treat them as such. So we splurge a little bit on snake oil rubbed into our backs... it's discretionary spending of disposable income, at least. Interest among Westerners in anything with the label Ayurvedic, whether massages or claimant medical treatments, has less to do with any particular merits, but simply the intrigue and allure of something exotic.

The biggest advocates of promoting Ayurveda as a serious form of medicine here in the U.S. all tend to buy into the school of Ayurveda founded by Maharishi Mahesh Yogi in the 1980s. The lord of woo, Deepak Chopra, is one of those wooed by his message. This is where the weirdest things start to come up and it's the kind of mumbo-jumbo that permeates this field. Mahesh Yogi's concept is pretty close to what a large fraction of the "certified ayurvedic institutes" teach in that there are some apparently irreducible influences called "doshas." The concept of a dosha is actually not an exclusively "medical" thing within Hindu culture, just to be clear. It actually has some significance in Vedic astrology and used to be common terminology in music theory (though the latter fell out of fashion in the early 16th century CE, AFAICT). You can think of it like a generic term for an "effect" or "aspect", really. Within astrology, a dosha may refer to some sort of planetary influence (e.g. mangal dosha). Within music, a dosha might refer to a relative dissonance (e.g. vivaadhi dosha). And in Ayurveda, it refers to some particular subset of your body's functions and/or how they may be affected. Although not everybody seems to simplify down to just the 3 dosha that Deepak Chopra and his ilk speak of, the basic principle is still pretty universal. The fundamental thesis of Ayurveda is that vital forces and aspects can be affected by various means and the goal is simply to balance all such aspects.

On the surface, the idea of aiming for balance in all aspects of your health seems like sound advice. Problem is that what constitutes an aspect of your health is not really well-defined. Even if I were to use such a generic term as "effect" or "aspect" to a real doctor, you'd get a pretty fuzzy response. After all, what really constitutes an "aspect" can be arbitrarily broad or specific as there is no such medical terminology. The Chopra woo defines "Vata", "Pitta", and "Kapha" doshas, and they're actually quite astonishingly broad. Vata dosha, for example, is said to govern "all functions of bodily movement" and apparently accumulates during cold weather, and is somehow connected to excitement, adaptability to change, mental alertness, blood pressure, arthritis, and restlessness. Just on that alone, we see a clear contradiction between the broad swath cut by this dosha and the notion that the dosha are all "irreducible." Anybody who has even a rudimentary basis of knowledge of medicine would be able to tell you that all these aspects are not mutually correlated. What exactly is "irreducible" about the dosha then? Why exactly is it possible for the dosha balance to change even within the span of a single hour? Why is it that someone who is apparently diagnosed as having more than one dosha "out of balance" is directed to "balance" them individually on seasonal boundaries? In all my efforts to get any clarity out an Ayurvedic practitioner, I have yet to get even a single incidence of clarity. In fact, the most common response I get is simply "just try it and see." For Ayurveds practicing here in the U.S., the response is almost always much worse -- usually, something along the lines of "To those who believe, all things are possible." Call me crazy, but I kind of like a certain aspect of science in that things are true whether you believe it or not.

There are those who argue that this school of thought is quackery, and contend that "real" Ayurveda is very different from the nonsense that Deepak Chopra feeds the public. What is interesting is that there actually is a pretty wide variety in the principles and what people prescribe. Some argue that all medicines should be in liquid form, some argue that all should be in whole food form, some argue that it doesn't matter. Some believe that adding heavy metals like gold and mercury (I wish I was kidding) to the tinctures will improve efficacy, others argue that wax/camphor will be more potent. Some will think the substances they sell alone will do the trick, others will lead you down dietary advice, and others still will prescribe yoga exercises to add onto the treatment. Worst of all is that they rarely agree on what should be offered for any particular condition. Now it's one thing for two different doctors to offer two different prescriptions or even differing diagnoses... it's another thing entirely for two different doctors to base their practice on entirely different principles and standards. Diagnostics is by nature ambiguous because a lot of our body's systems and chemistry is multifunctional. Any one substance, any one hormone, any one chemical serves more than one purpose in our bodies. This means in turn that it is entirely impossible to associate a given symptom with a single cause. Even a very complex mix of several symptoms can be linked to countless other causes. Narrowing down your diagnosis to something specific typically involves gathering more information than the obviously apparent symptoms. While two doctors may come to different conclusions, the idea of how they get there is basically the same. Ayurveda doesn't even have this sort of unified standard, so how on Earth is it trustworthy? Or more accurately, if there are indeed non-quacks among Ayurveds, how would you be able to tell? A real doctor at least has to be licensed to practice, and to work at a reputable hospital, certain standards must be maintained if a doctor is to continue to be able to provide care. Even an otherwise excellent doctor can have that license revoked for a single violation of basic rules and regulations... it seems harsh, but that is an institution in place to ensure that patients get care that meets a minimum bar of quality. Alternative practices have no such regulation. There is simply no concept of Ayurvedic malpractice, and they argue that it isn't even possible in the first place. I have heard countless times the argument that Ayurveda never has any side effects. Patients as well as practitioners say this to me all the time. This of course, is in every way impossible. Even if I were to ignore the people who practice the rasa shastra principle of adding heavy metals to their preparations (treating them as an anomaly), the multi-purpose nature of our body chemistry also means that if you have an effect on any one thing, it's going to also affect the other functions of that thing. There simply can never be a way around this. While this doesn't really cross the mind of a lot of people, people who should know better still spew this sort of tripe because they blindly accept anything Ayurvedic. I have people close to me who categorically reject all science-based medicine due to the influence of Ayurved family members.. some of whom actually make this claim of no side effects as if it is irrefutable fact in spite of the fact that they have knowledge and understanding of biochemistry which puts my own to shame (I am merely an engineer with an interest in math and science, not an actual scientist). Many of them most certainly know better than that, but the attachment to belief and tradition is stronger than fact. The simple truth is that Ayurveda is without a single shred of rigor in its principles, in its survey of facts, or in its testing. It's not that there are no side effects -- it's that there is no effort whatsoever in Ayurveda to even determine what side effects there would be. So as far as they are concerned, they just don't exist. Actual medicine reports side effects for every drug because they've actually gone through the trouble to verify their occurrence.

Now I happen to have in-laws who are Ayurvedic practitioners, and I am frank in my disapproval. Many would go as far as to blindly reject anything that science-based medicine proposes and only go with the Ayurvedic remedy. Within India, this has a tinge of nationalism to it because so much of scientific medical advancements came at the hands of post-industrial Western civilization, and the idea that this is the work of evil foreign minds creeps in rather than the idea that something should be evaluated based on its actual merits. To be fair, though, the practice of medicine is far more lax within India, so it is also difficult to pin down who to trust. Within the U.S., it happens because people are so terrified by the medical "establishment" that they distrust it implicitly and favor that which is so apparently different. Also, having a mechanism of being an "ancient" tradition as its mode of fake merit makes it easy for someone to hide lies about the process. Because Ayurveda is basically derived from centuries or even millennia-old notions collected about health and medicine and passed down either orally or through sparse and/or religious texts, it is easy to say that it holds a lot of things that it really doesn't. Either you can argue that we haven't fully come to understand the ancient writings in their full profundity (I feel the need to vomit when I hear this)... or you can claim that it had an outright cure for something science hasn't cured, but the corresponding texts have been mysteriously lost (which is basically just a bold-face lie wearing the "unfalsifiable" guise). It never really registers that this is basically no better than not having the knowledge at all, but it gives someone more comfort to believe that the answers are already there and we have to find it than to know that actual scientists are actually doing serious study on the subject to determine the answers. Well, that's what pseudoscience is good at -- claiming to have a "deeper" truth, but never actually demonstrating it.

One of the biggest mistakes people make when they recoil in disgust away from Big Pharma and leap into the arms of Big Placebo is this idea that because the philosophies are fundamentally different, the nature of treatment is not only fundamentally different, but entirely mutually exclusive. Hence, why you might hear the sorts of insane claims about how they can cure things where "Western" medical doctors gave up. Stories of this nature are invariably outright lies. In fact, where Ayurvedic remedies have some demonstrable value, it is also demonstrable that it happens to agree with actual science-based medicine. This may include things like home remedies that involve something of known efficacy to modern science all the way up to procedures like rhinoplasty. The key difference is that Ayurveda has no explanation for why or how anything works which is even remotely grounded in fact. Actual medical science can tell you that home remedy A works because of X, Y, and Z, and if you're really curious enough to find out, you can find answers right down to the molecular level of detail. Pseudoscientific quackery like Ayurveda can at best offer nebulous images of energy states and often times, astrological influences and nonsense about chakras and doshas and built-up stress. There is simply not one whit of hope to get any real answer which actually has some facts. Most Ayurvedic remedies which do work are of the nature of things which people tried at home centuries ago and figured it worked for them, and that's usually the best answer that can be offered -- anecdotal evidence. Now while anecdotal evidence is, by nature, the weakest of all forms of evidence, the fact is that it does mean that compared to far more bizarre alt-med nonsense like homeopathy, Ayurveda probably has a slightly better record of efficacy. That is to be expected since it has a longer history behind it, and along the centuries, someone is bound to stumble upon something which is correct.

So then, who do you trust? Someone who makes mistakes, learns, and corrects their thinking along the way and rigorously tests their ideas, or someone who is right by accident?

All of modern medicine can be said to be based on people who were "right by accident." And then someone came along, tested, occasionally made mistakes and learned from them. Fortunately, the people who are right by accident become quickly irrelevant or join the ranks of those who test and study. People who do not understand this, and essentially commit ancestor worship of the old ways, just make me sad...

I'm not quite sure how you mean that. You can bring up examples like penicillin or the vaccinia virus or some such "accident", but then those are the rarity. The majority of medical treatments, techniques, drugs, etc. are all devised by people who knew what they were doing and tried various methods to solve problems. Moreover, the people who happened upon those accidents are the same ones who did the testing and verification and isolation and/or explanation of the mechanism by which it works. Development in the field since then has largely relied on building upon the knowledge of those before. Yeah, they've always been guesses that were right, but they were never lucky guesses, but educated guesses... pretty much like any scientific hypothesis.

Do you mean that fundamental concepts like antibiotics and vaccines started from those sorts of happy accidents? If so, then I can more or less agree, but like you said, it didn't stop at the "right by accident" point. Ayurveda happens to stop there. Real medicine asks why it was right before doling stuff out.

Very well written article. I had to take a few breaks in reading it though :)

I for one cannot understand how some people can believe in anything that's thrown at them under the guise of "ancient wisdom," "what the elders say," etc.. and even "common sense."

Something else crossed my mind that I realized I forgot to mention in my original rant, and this is something that adds to the lack of trustworthiness of Ayurveda and alternative "medicine" in general. Basically, it's the point of medical liability.

It is in the nature of practicing medicine, whether you're a real doctor or a fake one, that you will inevitably screw up at some point and your patient will die. There's simply nothing that can be done to avoid this reality. One of the most psychologically taxing things that doctors have to deal with is the loss of a patient, especially when you're dealing with doctors who necessarily deal directly with their patients on treatment and/or procedure. But there's a fundamental difference I notice in the way alt-med quacks handle this as opposed to actual medical doctors.

When I talk to Ayurveds, homeopaths, acupuncturists, new-age crystal healers, etc... if any of them lose a patient, the first assumption they make is that the patient did something wrong. "[Patient] didn't follow my advice properly" or "[Patient] needed to come in more often for more treatment" or "Something else happened or changed about [Patient] after the treatment." Closest thing I've heard to admitting their own error is to say "[Patient] didn't provide me with enough information," which at least implies some error on the practitioner's part, but still puts the cause of that error on the patient's hands. Whatever it is, they seem to always shirk their own responsibility.

With real medical doctors, whenever they make such failures, their first assumption is "I missed something" or "I screwed up on the procedure/diagnosis" or "I didn't do enough tests." Closest thing they do to not admitting their mistake is to say they got the correct diagnosis+treatment, but caught it too late. Even cases where an insufficient medical history was the source of the problem, they do not put it entirely on the patient to provide all the necessary info -- partly because detailed records are accessible through the right channels, and also because they understand that getting the right information is a matter of asking the right questions.

That by itself is a huge difference. Yeah, I'm sure someone somewhere might be exceptions to these rules, but these are generalizations, after all. When you think about it, it also makes sense that there would be this sort of gap because alt-med practices are very faith-based, whereas real medicine is science-based. The objectivity of science includes and largely necessitates the admission of error. Faith and tradition are the sorts of things where you begin with the position that the principles are indisputably true and without error, so of course nothing is ever the "doctor's" fault.

Acupuncture, as far as I know, does indeed help. Not to be thought of as a healing procedure, it does in fact help a bit. This is explained by the simple fact that many of these alternative medicines and procedures are based on experimentation. Basically, over many years people have perfected these methods so that what they do finally correspond to actual influence on muscles, nerves, etc.

So they start with something of little value or influence and then see what works and what doesn't. From the start, they're thinking that it has to do with energy flow and whatnot. So when they reach a point in which everything sort of works, they say it's proof that what they're saying about energy flow is true, when they're missing the actual physical influence that the practices have on the patient's body.

I do, however, wonder about spa treatments. They're widely regarded as a fine expensive luxury, but I'm skeptical regarding their real effects.

Do special creams help with issues one may have? Special oils? Mineral waters? Hot stones?

I'm guessing all of these must have some physical effect, even temporarily, such as relaxation. But I remain skeptical.

Well, acupuncture proves to be effective for temporary relief of certain types of pain... It's not a healing or curative procedure at all, but it is shown to be effective in actual clinical trials.

That said, acupuncture has been compared to "fake acupuncture" where people stick needles in just about any safe location without any sort of connection to the hypothetical "chi network" that the belief system posits... as well as to "genuine" and "fake" acupuncture performed with toothpicks instead of proper needles, and the effect is basically the same whether you're doing acupuncture in accordance with the "ancient wisdom" or you just poke people at random. Also, using toothpicks showed typically better effect than the "real" acupuncture whether you placed the picks in accordance with rules of chi networks or not.

What that means is that acupuncture is still a placebo. Its effects are non-specific in that you cannot tie the effects to the procedure. Yes, it is a more effective placebo than others, but it is known that certain types of placebos are more effective than others. For instance, we've already known that pill placebos are less effective than intravenous/injected placebos, and those are still generally less effective than lengthy procedural placebos. Acupuncture being an apparently elaborate procedure carries with it a stronger expectation of effect, and is indeed more effective than a lot of other placebos.

I'm fairly sure that most any oil, cream, bath salts, whatever, has roughly similar effects to one another in the same category. Granted, there may be certain ones that have comparatively different molecular structures that make them easier to absorb through the skin, but the level of effect doesn't run very deep, and you get a lot more effect deep down through proper diet and health maintenance than through spa treatments any day of the week. Applying some exotic "body butter" apparently increases skin translucency, but that's really because you're seeing either a film of the "butter" itself or a slightly saturated outer layer of skin which is just naturally far more translucent than human skin normally is. It's pretty much an illusion.

Bath salts and mineral waters and so on have no real well-defined mechanism for their effects, if there are any. They just have these chemically interesting sounding names that give the impression that they do something. Honestly, these minerals and salts would not have much effect on your body unless you eat them. Try and do it from a soak in the tub, and the strongest effect is really coming from just having a nice warm bath. Hot stones and what not... please. Applying continuous heat to an area exhibiting muscle pain or soreness is one thing, but that's a far cry from expecting it to have any real effect on your health. About the only thing that stones have that other things may not is an amorphous structure that allows it to hold temperature for a very long time. But then, you could do just as well with ceramic materials. There's no special procedure to it.

It's largely a placebo once again from what I can tell. There's a strong expectation that it has some effect, and you might see some short term effect. Indeed, rubbing a special $100 lotion on your face will have some moisturizing effect, but any sense that it has a more significant effect than some $7 lotion is purely subjective. That also makes it easy to just slap any old claim on some new product and say that it has some exotic vital oil that will "melt" the stress away like magic.

Things like aromatherapy and other such garbage relax you 1) because you're expecting them to relax you and 2) because the scents are aesthetically pleasing to you, and that releases endorphines. It has been shown, IIIRC, that you can get a stronger effect from the scent of home-cooked food like mom used to make (or more accurately, anything familiar to you that reflects positive memories). Another aspect of spa treatments is the personal attention and pampering you get as a client. That's as opposed to the level you get when when you just apply a lotion on yourself or take a shower during the daily grind. It is also very integral in why alt-med practices are believable in that they give a lot more personal attention as compared to the seemingly rapid-fire approach that a lot of real physicians apply when seeing a patient. While this is a valid service worth paying for, it is very easy to forget about this when the very same person providing the service is giving you so much shpiel about the special capacities of various substances and procedures, when there is really a lot more effect coming from a hot masseuse than hot stones.

I obviously can't trust unfundamented claims, even in these forums. So, any sources, my friend? I'm intrigued :)

Adverse effects of acupuncture.

-----------------------------------------------

The part about spa treatments, I mentioned in the post (or at least, I tried to word it that way) was a lot of educated guesses. The main exception was the part about body butters being a translucent film and/or saturating a few layers of skin is something that has been tested, albeit in the context of computer graphics (which is my field) and being able to simulate the visual effects of light scattering in human skin. I personally took part in some BRDF measurements (I had to borrow a goniometer from another university) to test the effects of several variables on the visuals... that included things like wetness/dryness, clean/dirty, moisturized/unmoisturized.

One of the things that made me suspect that body butters may merely create a film of butter on top is the fact that some surface reflection energy was reduced (this could be seen in that the skin looked slightly darker under head-on lighting like the flash from a camera), but this wasn't always the case. Since the illumination from backlighting was increased, it was clear that translucency had improved. The variance in the effect is largely attributable to a lack of control and precision in exactly how to apply a given modifier.

Speaking of which, I wouldn't be entirely surprised, that spas might give you better results than you'd otherwise get on your own because of the difference in the method and the degree of attention. When you rub lotion on yourself, you may only spend a minute or so doing it and you'll apply a small handful, while a masseuse will probably use much more cream/lotion and massage it in for several minutes while you relax. That's got to account for a difference. In order to be really scientific about it, we need to consider the effects of those variables as well as for the actual substances.

The aromatherapy point about home-cooked food and all, my only reference for that was from Scientific American, which is technically a mainstream magazine, but the point they raised was simply about endorphine levels, which is something which has several well-established links. I think there's also a video of V.S. Ramachandran on youtube alluding to some examples.
