PATIENTS who believe herbal remedies and alternative therapies will cure cancer are putting their health at further risk.Researchers in Britain studied 32 of the most popular health websites that promote alternative therapies. They found there was no evidence to support claims any of the popular therapies, including shark cartilage, mistletoe and laetrile, could cure or prevent cancer. The University of Exeter’s Professor of Complementary Medicine, Edzard Ernst, said cancer patients were being misled. “We found that between these 30-odd sites, 118 different cancer ‘cures’ were recommended - complementary treatment that claimed to be able to cure cancer,” Professor Ernst told The Times of London.
