Homeopathy is a medical system based on the belief that the body can cure itself. Those who practice it use tiny amounts of natural substances, like plants and minerals. They believe these stimulate the healing process.
Homeopathic products come from plants (such as red onion, arnica [mountain herb], poison ivy, belladonna [deadly nightshade], and stinging nettle), minerals (such as white arsenic), or animals (such as crushed whole bees). Homeopathic products are often made as sugar pellets to be placed under the tongue; they may also be in other forms, such as ointments, gels, drops, creams, and tablets. Treatments are “individualized” or tailored to each person—it’s common for different people with the same condition to receive different treatments.
