ABSTRACT
Boric acid was formerly used as an antiseptic and to make talcum powder flow freely. Boric acid and borates are toxic to all cells. The effect on an organ is dependent on the concentration reached in that organ. Iodine acts directly on cells by precipitating proteins. The affected cell may be killed. The effects of iodine are thus similar to those produced by acid corrosives. Iodoform in large doses depresses the central nervous system. A large number of phenol derivatives have been used in the past as antiseptics, disinfectants, caustics, germicides, surface anesthetics, antioxidants, and preservatives. Phenol and derivatives must be stored safely. Phenolic ointments or solutions of derivatives such as hexachlorophene should not be used over large areas of the body. Silver nitrate sticks should be stored safely. Silver proteinates should not be used repeatedly for the treatment of mucous membrane or skin diseases.
