Homeopathy is a practice that has been around since before western medicine was documented. Homeopathy is the pseudoscientific system of alternative medicine. It is centered around the belief that a substance that causes. symptoms in sick people; this belief is called similia similibus curentur, or “like cures like.” The selected substance is repeatedly diluted in this process until the final product is chemically indistinguishable from the diluent. Those that practice homeopathy and believe in its benefit think that these remedies. usually taken orally, can both treat, and possibly cure disease.
