Edible Uses

Edible Parts: Leaves Edible Uses: Condiment Tea Leaves - raw or cooked as a potherb[50]. Used as a flavouring in salads or cooked foods[183]. The leaves have a similar flavour to spearmint, and are considered to be superior in flavour to that species but are also hairy, which makes them less suitable for garnishing[238]. A herb tea is made from the leaves[183].

Medicinal Uses

Antiseptic Carminative Febrifuge Round leafed mint, like many other members of this genus, is often used as a domestic herbal remedy, being valued especially for its antiseptic properties and its beneficial effect on the digestion. Like other members of the genus, it is best not used by pregnant women because large doses can cause an abortion. A tea made from the leaves of most mint species has traditionally been used in the treatment of fevers, headaches, digestive disorders and various minor ailments[222]. The leaves are harvested as the plant comes into flower and can be dried for later use[238]. The essential oil in the leaves is antiseptic, though it is toxic in large doses[222].

Known Hazards

Although no records of toxicity have been seen for this species, large quantities of some members of this genus, especially when taken in the form of the extracted essential oil, can cause abortions so some caution is advised.
