Medicinal use of White Peppermint:White peppermint is a very important and commonly used remedy, being employed by allopathic doctors as well as herbalists.

A tea made from the leaves has traditionally been used in the treatment of fevers, headaches, digestive disorders (especially flatulence) and various minor ailments. The herb is abortifacient, anodyne, antiseptic, antispasmodic, carminative, cholagogue, diaphoretic, refrigerant, stomachic, tonic and vasodilator. An infusion is used in the treatment of irritable bowel syndrome, digestive problems, spastic colon etc. Externally a lotion is applied to the skin to relieve pain and reduce sensitivity. The leaves and stems can be used fresh or dried, they are harvested for drying in August as the flowers start to open. The essential oil in the leaves is antiseptic and strongly antibacterial, though it is toxic in large doses. When diluted it can be used as an inhalant and chest rub for respiratory infections. The essential oil is used in aromatherapy. Its keyword is "Cooling".

The plant was therefore used in homes as a strewing herb and has also been spread in granaries to keep the rodents off the grain.
Propagation of White Peppermint:Seed - sow spring in a cold frame. Germination is usually fairly quick. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in the summer. Mentha species are very prone to hybridisation and so the seed cannot be relied on to breed true. Even without hybridisation, seedlings will not be uniform and so the content of medicinal oils etc will vary. When growing plants with a particular aroma it is best to propagate them by division. Division can be easily carried out at almost any time of the year, though it is probably best done in the spring or autumn to allow the plant to establish more quickly. Virtually any part of the root is capable of growing into a new plant. Larger divisions can be planted out direct into their permanent positions. However, for maximum increase it is possible to divide the roots up into sections no more than 3cm long and pot these up in light shade in a cold frame. They will quickly become established and can be planted out in the summer.
Cultivation of the herb:A natural hybrid, M. aquatica x M. spicata found in moist soils.
