BRIEF: Is St Johns Wart poisonous to humans?


QUESTION:
I have another question about St. Johns Wort. Is it poisonous to humans? I've been drinking the tea for about 2 weeks now.

ANSWER:
The dose is key. If you were grazing on the stuff and went out to do some sun-bathing, then you would have a problem, but the little bit of hypericin you get in a few sips of tea are unlikely to hurt you.
