I missed the first part of this quote in my previous response: Although acupuncture can be used with lymph disorders, lymph and chi are two completely different entities, and the treatments for them are different is well. From my experience, the movement of chi feels like some sort of energy, and is much more rapid than the flow of lymph could possibly be. Some people may say, "Wait a second. Energy is a very clearly defined entity in physics." It certainly is, as defined by the formula E = (mv(squared)/2), or in the famous formula E = mc(squared). But that just tells you how to calculate the amount of energy; it doesn't tell you what energy is. From the great quantum physicist Richard Feynman (also quoted in my signature): (This and many other perceptive quotes of his can be found on the Wiki Quote page for Richard Feynman.) Meanwhile, as for the use of acupuncture in lymph disorders, here is an excerpt from Study Shows Acupuncture May Relieve Chronic Lymphedema after Breast Cancer Treatment, done at the world-famous Memorial Sloan Kettering Cancer Center: As for the efficacy of acupuncture in general: I can't say "always" (people do make mistakes), but I can state from my personal experience and those of many people I know that acupuncturists tend to be as unanimous in their diagnoses as medical doctors are in theirs. Simply from a logical perspective, this makes sense. Without consistent diagnoses, there would not be consistent treatment for the same condition, and acupuncture would be useless as a treatment modality. Your own quotes from published papers support the assumption of consistent diagnoses. The study I quoted above is one. I'm sure you can find others easily. You have given no evidence for what you suspect. And as I pointed out, if it were true, acupuncture would be useless. In just the example that I quoted, the researchers at Sloan Kettering obviously disagree with you. In the example of my friend that I mentioned in a previous post, she had diagnoses from a number of acupuncturists and TCM practitioners, many from different countries. She even had diagnoses from Tibetan medicine, which shares some basic principles with Chinese medicine. All the diagnoses were the same. To you it is. To me and millions of other people, mostly in Asia, it is something tangible that can be felt, and that is different from anything described in Western medicine. I have experienced something that is described by TCM as chi. There is no cognate for this in Western medicine. This doesn't mean that I know exactly what chi is, any more than Richard Feynman knows exactly what energy is. And if we're talking about lack of objective proof of something that we all know is real, why don't we take a look at the elephant in the room and talk about consciousness? We all know it exists, due to our direct perception of it. But what objective proof is there? Physics attempts to explain the entire universe. But so far, it has made no inroads on the nature of consciousness. Some neuroscientists claim that consciousness is an epiphenomenon of the brain, but there is no evidence for this. There is certainly evidence that consciousness and the brain are linked, but what the nature of that link is is completely unknown at this point. I'll conclude here with a famous example of how Western medicine differs from Asian medicine. In Western medicine, a pulse is a pulse. It has a frequency and a strength, and that's it. In a given place in the body (e.g., the wrist), you have exactly one pulse. The following is taken from a radio interview with Diane Toomey: Note also that by simply examining the pulses, the doctor was not only able to detect the heart defect, but also to determine that it was congenital. I used to know more of the details of this particular incident, but although I have forgotten them, I'm sure you can find them in the book referenced in the quote.
