Homeopathic medicine is a system of alternative medicine based on the principle of "like cures like." This means that a substance that causes symptoms in a healthy person can be used in very small doses to treat similar symptoms in someone who is ill. Homeopathic remedies are often made from natural substances, including plants and minerals, and are diluted multiple times to enhance their healing properties. Practitioners of homeopathy believe that these highly diluted remedies can stimulate the body's natural healing processes. While some people report positive effects from homeopathic treatments, scientific evidence supporting their effectiveness is limited, and they are often considered controversial within the broader medical community.
