Why would one want to take herbs instead of drugs to treat illness.
Drugs play a particular role in healthcare, one that is well recognized.
They are lifesaving, relieve symptoms, prevent serious complications of incurable diseases, etc. Herbs also have a role to play, one that is still not completely understood at this point, I believe. In vogue right now are herbs that can used in lieu of drugs, but essentially for the same rationale. This is the case with saw palmetto which is prescribed for prostatic hypertrophy instead of the drug proscar or st. In the former case, the herb often works better and in the latter, at least as well.
