There's some specific information here, this atleast provides the basis for some meaningful discussion.
It's interesting that even among those who used SJW for depression, it was never indicated for severe depression. (which, of course still leaves the category of moderate depression) I also remember talking to one very knowledgeable herbalist who said he didn't understand what the big deal was, or how it was used for depression, so even someone who did not practice with the scientific method shared this view.
It's certainly helpful to have well designed studies, but I've heard many people who've tried SJW say that it does nothing for them. This may be (and is probably) true, indicating that people who are willing to try herbal remedies do not necessarily delude themselves, (which I would think is self evident) but then again there's always the question of dosage and stardardization with herbal products. You can interpret it either way.
The popularity of herbal remedies has boomed in North America in recent years, proof that the number of people who eschew conventional medical treatments and believe natural products are healthier is on the rise.Now I'm not sure if this is "proof" of anything other than the fact that people want to try other things. Yes some people will go after the "natural" label without even really understand what that really means, but obviously there are many choices out there, even when it comes to supplements or herbal supplements in particular. I think the key word there is popular, and despite the common tendancy for people to polarize this against that, conventional against non-conventional, (whatever that is) there are people who make truly informed choices rather than what's hot these days.
