Allergic Reaction - Which Herb?

[Guest guest]

I had an allergic reaction this morning while eating a mixture of

cat's claw, sarsaparilla and knotweed powders. Severe rash head to

toe, swelling in ears enough to cause pain and temporary hearing loss,

puffy face, eyes, throat, etc. Shaking chills. It settled down very

quickly with Benadryl, and all was well.

I wondered if anyone else has had this happen, and which herb it was.

I'll try taking very small amounts of one herb at a time, but it

would be nice to guess right. (Wish I had an epi pen.)

Thanks,

D.
