Dr Henry Miller of California's Stanford University led the effort and he was the first person to sign the letter, the New York Daily News reported. Columbia's Medical and Health Sciences Center . Miller said: 'He's a quack and a fake and a charlatan. 'I think I know the motivation at Columbia. 'They're star-struck, and like having on their faculty the best-known doctor in the country. 'But the fact is that his advice endangers patients, and this doesn't seem to faze them.' The nine other doctors from across the country included Dr Joel Tepper, a cancer researcher from the University of North Carolina School of Medicine, and Dr Gilbert Ross of the American Council on Science and Health in New York City. The physicians accused Dr Oz of pushing 'miracle' weight-loss supplements with no scientific proof that they work. The doctors wrote that Oz, for years a world-class Columbia cardiothoracic surgeon, has 'misled and endangered' the public.

'Thus, Dr Oz is guilty of either outrageous conflicts of interest or flawed judgments about what constitutes appropriate medical treatments, or both.

Dr Oz first came to public attention as a frequent television guest of Oprah Winfrey. For the past five years, he's been the host of The Dr Oz Show. Last year, he appeared before a US Senate panel that accused him of endorsing products that were medically unsound.
