The term homeopathy is formed from the combination of two Greek words: omio meaning “same” and pathosmeaning suffering.1 This etymology reflects the homeopathic belief that a substance that causes certain symptoms in a healthy person can cure an ailing person of similar symptoms. Although this theory sounds superficially similar to the principle behind vaccines, homeopathy actually functions in a distinctly different manner. The homeopathic theory has some relationship to ancient healing traditions, but in many ways stands uniquely on its own ground, unrelated to other approaches.
