Homeopathic medicine is a form of alternative medicine that uses natural substances to treat illnesses and promote health. It is based on the principle of “like cures like,” meaning that a substance that causes certain symptoms in a healthy person can be used to treat similar symptoms in an ill person. Homeopathic remedies are prepared by diluting the active ingredient in water or alcohol and then shaking it vigorously. Homeopathic medicine is used to treat a wide range of conditions, including allergies, asthma, headaches, and skin problems.
