Overview
Listerine is an American brand of antiseptic oral care products invented in 1879 by Joseph Lawrence and named after Joseph Lister, a pioneer in antiseptic surgery . Initially developed as a surgical antiseptic, Listerine later became the first over-the-counter mouthwash in the U.S., widely promoted for oral hygiene and fresh breath
