Today carvacrol and thymol are often used in dentistry and against mycotic infections of the oral cavity.
Prof. Günther from Göttingen analyzed the potential effectiveness of the ingredients thymol and carvacrol in oregano-oil if peroral applied. A group of piglets were feeded with an additive of essential oils and gained their weight about 7,2 %. They also increased their ingestion about 9,1%.
