When I was trecking in Nepal in the late 70's, every time I stopped in the hills people would crowd around with various ghastly infections, wounds, etc., seeking treatment from the westerner. I often did what I could with my meager med kit, but there were many times when treatment was beyond my resources and competence.
I also attended a lecture by a lama on a unique form of treatment similar to acupuncture. A metal template would be laid over an acupuncture point. The point would then be cauterised with a red-hot iron. The metalic template acted as a heat sink and prevented extensive damage to the surrounding tissue. This treatment was said to be quite painful, but I didn't verify that personally. I did see the equipment though.
I picked up body lice staying at a Tibetian buddist monastery. I slept for a number of days on the wooden floor with only a borrowed blanket for cover. When I got back to a pharmacy various aruvedic remedies were suggested to get rid of the lice. I however, asked for the most toxic poison available to kill the little buggers. So much for my wholistic, natural outlook.
