"i have found this herb to be an invaluable part of self-maintenance.  though i do not always take it, months will go by when i do not feel the need, i have relied on it for over a decade.  i come from a family with a history of depression and am one of the few that has never needed an anti-depressant drug.
one word of caution:  once a bottle of st. john&#039;s wort is open, i find that it loses potency with in a month or so.  i&#039;d stay away from large bottles, be careful how it&#039;s stored and there are other herbs that compliment it nicely: dmae (not to be confused with the hormone dhea!), valerian and such.
good luck!"
