Mint is a plant in the Lamiaceae family of plants. Other plants in this family include basil, chia seeds, marjoram, oregano, rosemary, sage and thyme.
Mint contains lots of essential oils, the most allergenic are considered to be Menthol and L-carvone. These are both linked with allergic contact dermatitis.
Menthol is added to a lot of medicinal products as well as toothpaste. It is sometimes artificially derived, but both artificial and natural menthol can cause contact allergic reactions.
Mint is high in salicylates
. Salicylates have the potential to cause worsening of asthma, swelling, itching and hives as well as food intolerance symptoms in people who are sensitive to salicylates.
