Description and Uses

Thymol is used as a preservative in halothane. It acts as an anesthetic, antiseptic in mouth wash, stabilizer in pharmaceutical preparations. It inhibits the growth and lactate production as well as reduces the uptake of cellular glucose within the bacteria. It is an active ingredient in toothpastes like euthymol. It is involved to control varroa mites and prevent fermentation and the growth of mold in bee colonies.
