Classical homeopathy is a form of alternative medicine that follows the principle of "like cures like," which suggests that a substance that causes symptoms in a healthy person can be used in diluted form to treat similar symptoms in a sick person. This practice is based on the teachings of Samuel Hahnemann, a German physician who founded homeopathy in the late 18th century. The term "classical" distinguishes this approach from other forms of homeopathy that may use different methods or combinations of remedies. In Hebrew, classical homeopathy is known as הומיאופתיה קלאסית. Key aspects of classical homeopathy include the use of highly diluted substances, often to the point where no molecules of the original substance remain, and the individualized treatment of patients based on their specific symptoms and overall health profile. Despite its popularity in some circles, classical homeopathy is not widely accepted by the scientific and medical communities, which cite a lack of empirical evidence supporting its efficacy beyond the placebo effect. Translations of "classical homeopathy" in other relevant languages include Homéopathie classique in French, Homéopatia clásica in Spanish, and Klassische Homöopathie in German.
