What are your thoughts and experiences with/about St. John's Wort?

I’ve been suffering from moderate depression (undiagnosed, no insurance) lately and I’ve heard for a long time that St. John’s Wort is an herbal supplement that aids that ailment. And apparently, science agrees.

But I’m curious about people’s opinions. What are yours on the supplement?

And I know similar questions have been asked, but from what I’ve seen, none of them answered what I’m asking.
