Well, there are a lot of "weeds" that are both food and medicine. I guess by categorizing something as a weed that would infer that it took little maintenance to grow, lol.
It was not my business that I was working for, I was just managing a section of the company. I could write a book on what I see wrong with herbal medicine being brought into mainstream commerce. As a more traditional herbalist it really does trouble me. I'm old school....I think one should have a connection and knowledge of the plant. One of the main reasons I left the company. But there are some pretty good gigs out there working with smaller companies that would want to source" weeds" or herbs from smaller farms.
