Homeopathic natural care, also known as homeopathy, is a system of alternative medicine that treats patients with heavily diluted preparations, which are believed to cause effects similar to the symptoms of the disease being treated. The term "homeopathic" is derived from the Greek words homoios (similar) and pathos (suffering), reflecting the principle of "like cures like." In Hebrew, homeopathy is referred to as רפואה הומיאופתית (R'fuah homeopati't). Other relevant translations include homöopathie in German, homéopathie in French, and omeopatia in Italian. Homeopathic practitioners believe that the dilutions, often to the point where no molecules of the original substance remain, retain a "memory" of the original substance and can stimulate the body's natural healing processes. This practice is highly controversial within the scientific and medical communities, as numerous studies and systematic reviews have found that homeopathic remedies are not effective beyond the placebo effect. Despite this, homeopathic natural care remains popular in some countries, often as a complementary or alternative therapy.
