Hey Michael...You are definitely asking a question that is outside of my realm of expertise. I have to be honest with you before I go into too much detail. I do have a PhD, and my education is in horticulture and plant biology, but I am not a medical doctor. I can tell you what I do know about the plant. Feverfew is known by its Latin name Tanacetum parthenium. I would be concerned with using it medicinally since handling the leaves can cause dermatitis and eating the leaves have caused mouth ulcers in some people. I'm sorry that I cannot give you more information. I would feel uncomfortable giving medical advice when I am not a medical doctor. :( --Robby
