I don't know what Paxil does, but I can tell you that St Johns Wart has been
very effective in relieving depression and anxiety. I remember one study, I
think it was out of Sweden but I'm not sure, that showed it as effective as
Prozac and more effective than a placebo.
You need to take it for 3 weeks or more. It tends to slightly reduce the
amount of sleep you need. There are some reported problems when taken with
certain other drugs or foodstuffs as it is essentially a powerful herbal
drug.
