Carvacrol in oregano: the key compound and the role of thymol in the plant
In brief: Research indicates that carvacrol and thymol help us understand the chemistry and biology of oregano. Their levels vary between species, chemotypes, and products. Therefore, these products do not have the same profile. The most robust data come from laboratory tests and composition analyses. The key takeaway requires caution. These substances help us better understand oregano, but the spice, essential oil, and concentrated extracts are not equivalent.
