Well, for starters, there's Jenny's improvement/remission, don't you think?
And while we are on this subject, are there any published studies that show the TCM concepts of dampness, dryness, heat, cold and wind have practical healing utility?
I'm sure there are studies on various TCM patent medicines (which are often a blend of heating and cooling herbs), but it might be easier to explain the heat-cold-etc. theory by using this example:
Capsicum (from red chili peppers) is a very hot spice. It's used by some to improve circulation and I believe also for arthritis and other joint problems. Or instead of capsicum, let's use garlic or onion. If one takes or eats any of these for an extended period of time by themselves, one could become very hot and uncomfortable overall, or one's stomach or gut could become inflamed from those herbs/foods. So, the logical thing to do would be to stop them, or add something cooling or cold that balances them out.
The same could be said about lemons, limes, or say even drinking cold water or milk, without balancing them with warming foods/drinks/herbs.
From my personal experience I had the best years of my illness when I was seeing acupuncturists at a low-income clinic. I'd go in feeling stiff, sore, agitated and with a variety of other neuromuscular complaints -- especially chronic fasiculations in my feet. And very often my treatment would include a 'presciption' of a combination of various herbs.
After the treatments -- on every single occasion with perhaps two or three -- I'd walk out feeling almost normal. It wouldn't last for more than 8 hours or so, but it suggested to me that there were indeed energy blockages that were part of the problem.
At one point, I started developing strong, strong cramps in my legs, especially at night. When I mentioned this to the (best) acupuncturist there, she asked me what spices I was adding to my meals. "Capsicum", I replied.
She shook her head in dismay and told me to stop it immediately. According to TCM, the spices were heating me up so much that it was depleting my yin (fluids).
So I stopped the capsicum, and sure enough, the strong cramps stopped.
