In 1879, two scientists-Dr. Joseph Lawrence and Pharmacist Jordan Lambert—joined forces to create LISTERINE®, a powerful formula made from four essential oils. More than 100 years later, those same four essential oils combine to pack a powerful punch against hard-to-reach plaque and germs that can cause bad breath and gum problems. No other branded mouthwash offers this unique, four-ingredient formula that penetrates to reduce plaque in depth and help keep your mouth clean and healthy. Our fixed combination of eucalyptol, menthol, methyl salicylate, and thymol continues to deliver results.
Derived from trees usually found in Australia, this essential oil acts as an antibacterial agent.
Identical to the thymol in natural thyme and ajowan herb, research continues to demonstrate this essential oil's effectiveness against bacteria.
Oil of Wintergreen
Identical to the oil found in natural wintergreen, this essential oil is also often found in chewing gum due to its fresh-flavoring properties.
Identical to menthol found in natural corn mint, this essential oil is known for its germ-killing properties.
