Homeopathy is based on the principle that substances, which are poisonous in large doses, can be very beneficial in small doses. Homeopathy is a form of medicine that treats the body as a whole and helps it to heal itself. It can be used for acute and chronic illnesses. The objective is to prevent the patient from getting the illnesses again. Homeopathy looks at each patient and develops an individualized remedy or treatment plan. Homeopathic remedies are made from naturally occurring plant, animal, or mineral substances.
