Regarding plants as medicine, the United States is at this time a country where there is no nationwide profession that specializes in herbal medicine. Naturopathy is still at this point more of a regional phenomenon. My own view is that I don't see herbal medicine per se as a specialty in this way, or as a medical system. The use of plants is common to every alternative system . . . Using plants and natural products is part of it.
Nutrition is a focus.
So is lifestyle. I don't know. That's an open question. I think it's a difficult challenge. When you mention naturopathy, I look back at history.
