Homeopathy is a medical system that treats a disease or symptoms with minute doses of a substance or drug that would induce similar symptoms in a healthy person. A "homeopath" is the person or doctor who provides these types of remedies. A homeopath believes that the body produces symptoms as one way it fights disease. Thus, those small doses help produce the symptoms that will treat the disease.
Homeopathic medicine is controversial and is considered a form of alternative medicine.
