As a homeopathic physician, Lee discouraged the use of drugs, especially coal tar based drugs such as aspirin, phenacetin, and acetanalid. The underlying principle of homeopathy was “like is cured by like.” The homeopathic method of treatment is based on the practice of administering minute doses of a remedy that in healthy persons would produce symptoms similar to those of the disease being treated. The human body’s natural systems of disease defense would combat the disease or ailment, providing a natural curative reaction. The homeopathic physician believed that therapeutic drugs, such as pain relievers, did little good and the best remedy was the body’s natural ability to repair itself.
