Spearmint

Spearmint is a perennial mint, 30 to 100 centimetres tall with a square stem and pink or white flowers, native to Europe and southern temperate Asia and naturalised elsewhere. Wikipedia also calls it garden mint, common mint, lamb mint and mackerel mint, and says it is used as a flavouring and in herbal teas. Cunningham calls it feminine, with Venus and water, and lists healing, love and mental powers. He says it is used in all healing applications, especially for lung diseases, and is sometimes used to provoke lust. Smelling it is said to sharpen the mental powers, and stuffing a pillow or mattress with it gives protection while asleep. Kynes heads peppermint, spearmint and water mint together under one mint entry, so this file does not cite it. The American Herbal Products Association lists the leaf as the part it covers and records hazards, set out in the safety notes.
