boric acid

 [bor´ik]
a mild acid used as a buffer. It was formerly used as a household antiseptic for treating minor irritations of the skin and eyes. Because the powder is highly poisonous when taken internally, and since other antiseptics are more effective, boric acid is no longer recommended. Boric acid ointment (for external use only) occasionally helps in cases of mild skin irritations and keeps gauze dressing from sticking to a wound. It is also used as a pesticide to kill ants and cockroaches.
