Homeopathy pills in a patient's hand. Homeopathy is a form of alternative medicine in which chemicals that cause the same symptoms as the condition to be treated are taken in tiny doses. Practitioners believe that the more dilute a homeopathic solution, the more powerful it is. Conventional medicine in general does not support the claims of homeopathy.
