Carvacrol and thymol
Carvacrol and thymol are isomers and derivatives of phenol, if viewed chemical. They are important ingredients of the essential oil in oregano.
The Egyps used carvacrol and thymol because of the antifungal and antibacterial effects for the conservation of mummys.
Carvacrol and thymol are recovered as oregano oil from oregano and were known for a long time as an antibiotic for poor.
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%.
Prof. Günther resulted that the essantial oils in oregano are digestives. Because of the appetizing effect carvacrol and thymol are highly recommended for using them in conventional husbandry.
