What pharmaceutical companies buy medical plants/herbs such as sage, lavender etc as raw materials?

A lot of the herbal plant products that are sold in the US are owned by big pharma. The big corporations smell money, the herbal biz is a multi-billion dollar industry. A buck is a buck. If you hate the Rx pill industry, and so big pharma, you can buy the herbs they sell you. They really don't mind if you don't like the pill company and turn to herbs instead.
