Prince Charles is a vocal advocate of complementary medicine, including homeopathy. In 2019 he became patron of the Faculty of Homeopathy, which trains practitioners around the world. "For the past 24 years, I have argued that patients should be able to gain the benefit of the 'best of both worlds' – complementary and orthodox – as part of an integrated approach to healing," he said in a 2006 speech.
His mother's longtime personal physician, Dr. Peter Fisher, was also a champion of homeopathic medicine. Dr. Fisher served as physician to Queen Elizabeth II for nearly two decades, until he was killed in a cycling accident in 2018.
