Just some info i picked up. One of the world's authorities on mercury detoxification, Dietrich Klinghardt, doesn't use it anymore because he found it releases aluminium into the body. He's not usually far wrong. But i guess it's different for every user. It can help to realkaline the body. But i'm interested to know if anyone has been helped by it for severe symptoms, particulary mental. I remain an open minded sceptic.
