I would be cautious in the extreme about any treatment, either mainstream or complementary, that involves ingesting a substance, either synthetic or natural. Lots of 'natural' things can kill you naturally. And I'm very wary of chelation therapies. But practices such as qigong, tai chi, yoga, meditation are very safe indeed. They are also relatively cheap and effective. The problem lies in learning to develop the self discipline to stick with them when benefits are slow to accrue, ESP if your physiology and biochemistry is compromised by meds. Because these methods are slow to work your life circumstances need to be stable to make the most of them. Many people are pressurised into taking meds because everyone around them wants them to function now. But there is a big price to be paid for functioning now, without due regard that you might have to pass 20 or 30 yrs from point of dx.
