Peppermint is an herbaceous rhizomatous perennial that can grow to 80-90 cm tall and smooth-stemmed with a square shape. Peppermint is also a fast-growing plant, once it grows, it can spread very quickly.

Peppermint plants usually grow wild in damp, shady areas, such as on the edges of streams or ditches. The hybrid usually does not produce seeds and reproduces only asexually.

Peppermint was once grown for its oil use and is considered invasive in Australia, the Galapagos Islands, New Zealand, and the United States, dating back to 1843.


Peppermint plants can be extracted and produce oil. The oil is used in traditional medicine to treat minor ailments.

The extracted peppermint oil has a cooling effect when used topically for muscle pain, nerve pain, itching, or as a fragrance.

Fresh or dried peppermint leaves are often used to make peppermint tea or herbal teas.

Peppermint is known to be used to flavor ice cream, candy, fruit preservatives, alcoholic beverages, toothpaste, shampoo, soap, and skincare products.

The use of drugs produced from peppermint plant extracts has not been legally or safely approved by the Food and Drug Administration (FDA). However, it is considered safe by the European Medicines Evaluation Agency, if used for adults.
