It is also used as a preservative in halothane, an anaesthetic, and as an antiseptic in mouthwash. When used to reduce plaque and gingivitis, thymol has been found to be more effective when used in combination with chlorhexidine than when used purely by itself.

Thymol crystals is used in pharmaceutical preparation as it has antibacterial, antifungal and antiseptic quality. No Preservative or No Chemical is used. It is pure vegetarian product. Thyme oil is used as a germ-killer in mouthwashes and liniments.
