There are more than 6,000 unregistered and untrained practitioners of homeopathy in and around Calcutta and their number is growing, thanks to the immense popularity of this branch of medicine among Bengalis. These untrained homeopaths treat, between themselves, more than 1.5 lakh patients a day. The 3,500 registered ones—graduates from the state's five homeopathy colleges—do better business, treating about 2.5 lakh patients a day.
