I just want to reinforce what has been said several times above: St John's Wort *may* be very dangerous *in certain circumstances.* Jeri's link is excellent. I would urge anyone who's interested in SJW to read every word, and then go on and read the sites that are referenced there.

This isn't a blanket argument against taking it; but you should be well informed.

I've had bronchitis for two weeks. Because of my own hypersensitivity to medications, I don't take much for it, but I took something to help me sleep on two occasions. The first time it was a combination "cold" pill. One pill. Half the recommended dose. I felt horrible, and had heart palpitations. So the next night I just took one sudafed. Still heart reactions. My doctor said, yes, there have been fatal heart attacks from sudafed. Whoa.

I mention this to demonstrate that a medication that seems pretty harmless and is very commonly used, can cause real problems in certain circumstances. One has to be educated about any drug whatever, and maybe more with the herbal ones because there isn't wide spread knowledge of them.
