Does anyone else use gems?

There is medicine and other stuff that's based on plants. My brother, a biologist, currently does research on plants, and I know they're used for everything but the kitchen sink. I am just saying "herbal healing" as practiced by hippies and charlatans is not equivalent to the real thing. A real doctor might prescribe Valerian Root, but they wouldn't repeat the phony "herb healing" stuff of these phony storefronts.
