Interesting. Reminds me of some medieval medicine when they talked about bad odors versus good odors and had "humors" in different colors, etc. But, you know what? For all the mumbo-jumbo medieval doctors talked, they actually did some good. Leeches have been rediscovered recently as a very good thing for improving blood flow, especially in the case of re-attached severed digits and limbs. Maggots and even blood-letting have also been found to have their uses medically.
I wonder if where I live now is more damp than where I lived before? While my bowel problems are no better or worse, my overall health is much affected; I catch every little thing that's going around and then some. Still, I only moved from one part of TN to another; I would have thought it just as humid in my old location. I still say the lack of trees and/or too much grass makes the difference.
We have someone on here a long while back who was half Chinese and he finally told his dad about his D problem and his dad did got him some traditional Chinese herbs and things (including a thing you burned and inhaled) and it fixed him right up. He said it floored him that it had worked. He was especially skeptical about the part you had to breathe in (how does that help the colon?), but that made him into a believer.
