Chlorodyne was one of the best known patent medicines sold in the British Isles. It was invented in the 19th century by a Dr. John Collis Browne, a doctor in the British Indian Army; its original purpose was in the treatment of cholera. Browne sold his formula to the pharmacist John Thistlewood Davenport, who advertised it widely, as a treatment for cholera, diarrhea, insomnia, neuralgia, migraines, etc. As its principal ingredients were a mixture of laudanum (an alcoholic solution of opium), tincture of cannabis, and chloroform, it readily lived up to its claims of relieving pain, as a sedative, and for the treatment of diarrhea.
