Very interesting, every culture has their own little things. For good or for worst a lot of non Chinese do believe in some of the Chinese remedies. When i went to China, I was very ill; I ended up going to the hospital and the first thing they gave me was hot water. I was told it would help me stabilize my body. I sat in the waiting room just drinking water, the hotter the better. So, I asked my Chinese colleagues, yes, in fact, they do believe it is curative. Actually, one of them told me that she has never had iced water in her life.
