Thank you for great response -- it gives me something to think about.
1. According to Patricia Tsang, an UCSF MD specializing in TCM, Qi is simply a term for blood circulation. So increasing Qi is a fancy way of saying improving circulation. And if improved blood flow were one of acupuncture's mode of action, comparing acupuncture and sham acupuncture just doesn't make sense, really. Increased blood flow will always help remove cytokines and stimulate healing.
So the placebo effect in testing acupuncture will always be an issue. But acupuncture is often used on animals to great success. Pet owners deluge the local vet during the allergy season to seek acupuncture -- with great results. So the effectiveness in animals seems to argue against the placebo effect. (Pet-lovers, however, might disagree).
2. I'm not too familiar with the FDA approval process, I admit. So thanks for telling me about it. I'll try to learn more in this regard.
But another question of mine is this. Is it even more unethical to withhold therapies with very low risk and some evidence of efficacy, than it is to not offer them the option at all, especially if they are willing to pay? For example:
[Survival time of advanced gastric cancer patients treated with integrated traditional Chinese and Western medicine therapy]
CONCLUSION: Integrated traditional Chinese and Western medicine can prolong the survival time and improve the quality of life of advanced gastric cancer patients, and enhance the comprehensive effects.
Many similar studies have come out from China. I will admit that Chinese studies are bound to have a regional bias, since TCM is so ingrained in their culture.
3. I agree with you. A promise is hollow if the therapy doesn't work. But I haven't seen any practitioners at the holistic clinic promise anything of that sort, like a cure for cancer for dying patients. Good holistic practitioners, despite their bad rep, have scruples also, and are not as unethical as you set them out to be. And they often employ the sliding scale of evidence. The greater potential risk of a treatment, the greater evidence that is required. So you need lots of evidence about chemotherapy, but not so much with yoga. The MD I work with uses this model of thinking.
4. Perhaps you are right about the money thing. That disenchants my idealistic self a bit.
Okay, I typed too much for now.
I've seen several who don't, but for the sake of argument I'll spot you this point.
1) There's not reputable evidence that these therapies work. They don't make sense theoretically (you can't realign your chi's flow along meridians with metal needles because there is no such thing as chi or meridians) and they don't hold up to scientific testing (sham acupuncture has the same effects real acupuncture).
2) When you are charging for a treatment, it is unethical try a therapy merely because it 'might' help. This is why we have such a long FDA approval process: two of the three phases of FDA drug approval are concerned entirely with determining whether a drug works, not just whether or not it harmful. We consider it unethical to take a patients money in exchange for a drug that mere 'might' work. A con artist is every bit as much a thief as the guy who puts a gun in your face and takes your wallet.
A promise is hollow if the therapy doesn't work, no matter how little they're actually promising. I'm aware that the promises are usually vague and noncommital. That's how they can keep doing it year after year. If they promised cancer patients that they could cure cancer they would be out of business (and in jail) pretty quickly. However if they promise a canceer patienthat they can maybe improve some of their chemotherapy pain, well that's hard to measure, isn't it? They're still relying on the desperation of miserable people.
The reason that they're adding integrative branches into their cirriculum (and into their hosptials) is that they're profitable. They're cash businesses with no overhead, all it costs is your integrity. That's what's disappointed me so much about the push for doctors to do CAM: it is the most blatant conformation I've ever seen that Doctors care more about money than their patients.
