Mint is a perennial plant of the Lamiaceae family, which with more than twenty five species (pennyroyal, spearmint, water mint), some of which are ground covers and do not exceed three centimetres (Corsican mint). 


It likes a drained, fertile and cool soil. Its leaves are covered by rounded secretory hairs in which fragrant volatile substances accumulate.

The history of mint goes back to a domestic dispute in Olympus. Hera was furious to see that Zeus, her wayward husband, was holding the nymph Minthe too closely and transformed her rival into a wild plant, however she forgot to deprive her of her fresh and tempting fragrance. Hippocrates and Aristotle mistakenly believed that the plant was an aphrodisiac since it was born from a lascivious nymph. In reality it is only a tonic and a stimulant. Mint leaves have been found in sarcophaguses in Egypt and it is mentioned as a remedy for stomach pains in the Ebers Papyrus, the oldest known medical treatise. Five centuries B.C. it was prescribed in Babylon to relief abdominal pains, and today it plays an important role in the food industry. Romans perfumed their wine with it, in the same manner as tea is flavoured in the Arab world. A friend of clear thoughts and logic, it played a stimulant role for students to whom Pliny recommended to wear and braided mint crown on the head.

The various mints are cultivated throughout the world, especially in India, Morocco (Mentha viridis), Europe and North America. Peppermint needs sixteen hours of daylight to flower. The market of essential oil of mint is one of the biggest in the world and the United States are the first producer. France produces little, however the quality is remarkable.
