Homeopathy is a holistic treatment which works by boosting the immune system of our body and most of all. It is a medical practice in which extremely dilute amounts of certain natural substances are used to treat various ailments. Although homeopathic medicines are sold in health food stores and at high-end groceries, homeopathy is largely considered quackery. No scientific evidence supports its use; the theory of how homeopathy could work is beyond the realm of known physics, and governments worldwide are increasingly denying insurance payments to cover homeopathic treatment. It is 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.
