Alfredo Bowman, born November 26, 1933, was a herbalist and self-proclaimed healer whose client list included a number of celebrities. Lisa 'Left Eye' Lopes, John Travolta and Michael Jackson are all reported to have been clients. Bowman claimed to have developed a miraculous herbal cure for a host of "pathologies", including "arthritis, asthma, cancer, AIDS, diabetes", and placed adverts to that effect. He never studied medicine and did not have a medical licence. Who is Dr Sebi?
