History & Folklore

Horsemint’s genus name, Monarda, was bestowed in honor of Nicolas Monardes, a Spanish physician, whose herbal of 1569 detailed the medicinal uses of a number of New World plants. Horsemint was used by the Winnebagos and Dakotas as a stimulant and as a treatment for cholera. Other Native Americans used the herb for a wide variety of problems, including nausea, backache, fluid retention, chills, and headache.

Medicinal Actions & Uses

Having a strong volatile oil, horsemint is primarily used for digestive and upper respiratory problems. It is taken as an infusion to relieve nausea, indigestion, flatulence, and colic. It is also employed to reduce fevers and upper respiratory mucus. The herb has an antiseptic action within the chest. Taken internally or applied externally, horsemint reduces fever by encouraging sweating. It also strongly stimulates menstruation.
