I have read some of his writings, and I think he has some very good ideas about holistic healing, I saw how effective some Ayurvedic medicine is when I lived in India. I also really like the chinese aproach to holistic healing and have used many chinese herbal remedies.
I don't think it is wise to look at all forms of 'old medicine' as being good, some of the practices were useless or even dangerous. The same as ignoring all new knowledge as being allopathic. It goes back to the same old thing, do your research and make up your own mind.
