Information about St. John's Wort for School Project

I'm doing a project for my honor's chemistry class. I think I'm going to do it on how one herb and a medicine (man-made) compare. I was considering using St. John's wort and another antidepressant drug. I need good sources of information and stuff and I found your sight. I was wondering if you could help me. I would like to know the side effects, the chemical properties (if you know them), other benefits, etc. of St. John's Wort.

St. John's wort is a very interesting herb to choose for your project, both because of its effectiveness in treating depression without negative side effects, and because of the recently discovered information that St. John's wort stimulates a liver enzyme that increases the metabolism of certain prescription drugs, resulting in the drugs being available in the body for a shorter time.
