Alternative medicines 'potentially unsafe'

Edzard Ernst, the country's only professor of complementary medicine, said trials into treatments like chiropractic manipulation, acupuncture and herbal remedies too often failed to record incidents when patients suffered adverse effects.
Studies were frequently run by "enthusiastic amateurs" more concerned about promoting alternative medicine than accurately reporting the science, he said.
While his research indicated there were conditions for which alternative medicine could be useful, he believed in most cases people should steer clear because the balance of risks and benefits was not positive.
Chiropractic manipulation could even be "lethal", said Prof Ernst, of the Peninsula Medical School in Exeter.
"Most people believe that alternative treatments are safe. But how sure are we that this is true?" he asked.
