Research & Evidence
p-Cymene is an aromatic monoterpene hydrocarbon found in the essential oils of many herbs, including thyme, oregano and cumin. It is closely related biochemically to carvacrol and thymol, being a precursor to and breakdown product of those phenols, and it contributes to the aroma of the herbs that contain it. It is used as a flavour and fragrance component and as a solvent.
Toxicity & Safety
p-Cymene is present in common culinary herbs and is consumed in small amounts as a flavouring without notable concern. Like other essential-oil hydrocarbons, the concentrated compound can be irritating. A detailed isolated-compound toxicology in humans is limited.
