Leonurus

a genus of plants of the family Labiatae. The plants are perennial or biennial herbs with four-angled stems. The leaves are usually three-parted, five-parted, or lobed. The flowers are in dense false whorls, forming spicate inflorescences at the tip of the stem and its branches. The calyx has prickly teeth.

There are about 15 species of Leonurus, distributed in the temperate belt of Eurasia. The USSR has 13 species, including the valuable medicinal plants L. quinquelobatus and L. cardiaca. The former grows throughout almost the entire European USSR, in the Caucasus, and in Western Siberia. L. cardiaca, which is commonly known as motherwort, is found mainly in the western USSR. Both species contain essential oils, tannins, bitter substances, and alkaloids. An infusion or tincture can be used as a sedative. Plants of the genus Leonurus are nectar bearers.
