Often confused and referred to as a monoterpene, para-Cymene has a chemical formula of C10H14 and thus does not adhere to the C10H16 requirement to be a true monoterpene. Para-Cymene is found in many essential oils in small amounts but is a primary component in the essential oils of thyme, oregano, ajowan, savory and cumin.
