No, that's not my definition. A very large number of Western-used herbal medicines have an established evidence-base and work through identified pharmacological mechanisms. I can supply the scientific references if needed.

And if you're trying engage in a meaningful discourse on this subject rather than rubbishing herbal medicine I hope you know what you're talking about. I've been working full-time as a biologist in the "conventional medicine" area for more than 15 years with specializations in the safety and efficacy of therapies. Your post of 12:12 above suggests to me you don't know a great deal about herbal medicine.
