Where do you get blood wart?!
Question:
Where do you get blood wart?
Answers:
Could you mean bloodroot? If so, it's Sanguinaria canadensis and it's considered a toxic herb so it won't be readily available.
On the other hand, maybe you DO mean bloodwort and, if so, it's just yarrow. (Achillea millefolium) Again, not an herb used much because of safety issues but check w/ any large health food store.
