Hi, Further information about thymol: Many chemical companys sell Thymol (Merck, ICN, SIGMA); the price varies between $15 and 25$ for 100 gram, for The Netherlands, maybe for the USA cheaper. Ask first your local chemist's or druggist's shop, they will order it for you if not in stock. Moth's balls (from your wardrobe) contain Thymol and Campher, so it is a very common substance. From two publications: 1. honey contained 0.04 mg Thymol/kg after (but how long?) application. 2. honey containing 50 mg Thymol is undangerous to human. 3. waxsamples contained in March 45 mg/kg, but decreased to 0.15 mg/kg in May source: Deutsches Bienen Journal: (1993)8, 430-433: Stefanie Schultz Apidologie (1991)22, 135-145: F.Chiesa LD50 orally in mice is 1.8 g/kg, for Nicotine LD50 is0.06 g/kg.
