- Motherwort (Leonurus species) is a plant that is native to Asia but grows all around the world. The leaves look like the tail of a lion, giving motherwort the nicknames "lion's tail" and "lion's ear."
- Motherwort has a long history of use in Chinese medicine. Motherwort has been used most widely for women's health, including childbirth, afterbirth care, irregular menstrual cycles, and premenstrual anxiety, as well as to treat heart disorders.
- Motherwort has been studied for use in a variety of conditions, including prostate disorders, arthritis, kidney disease, and stomach problems. However, there is little information on the effects of motherwort alone, and more high-quality trials are needed before conclusions can be made.
