My ND firmly believes that OCD is treatable with diet and supplements.

I agree with you about looking at psychological and environmental factors. Where we get into treating things with herbs and "natural" things like 5-HTP, though, is more of a grey area. For example, if mercury poisoning is your problem but you don't know it and you are looking for ways to boost your serotonin, you're pretty well going to be sunk. I think there is too much made out of the idea of boosting neurotransmitters. Originally it was big pharma propaganda to sell Prozac because they discovered it acted on serotonin (it was originally developed as a drug to lower blood pressure). Lilly then started to sell the idea that depression is caused by low serotonin, though this has never been proved, and it is currently impossible to measure the neurotransmitter levels of a living human being.

I tried 5-HTP myself. It made me very groggy. I tried St. John's wort. It gave me severe stomach cramps. Diet, supplements, amalgam removal and chelation have worked for me where nothing else did; and in a way I'm lucky, because if all the sticking-plasters I tried did work to mask my symptoms, I never would have gone beyond them.

There's great advice about herbs, vitamins, etc on the Mercury forum. One of the best places for that on the internet, I would guess. It's nice to be someplace where people aren't pushing their psych meds. Many people here have already been down that route and have not been helped.
