Leonurus japonicus, commonly called Chinese motherwort, is a herbaceous flowering plant native to Asia, including Korea and Japan, and China to Cambodia.
Description[edit]
Plants are annual or biennial, growing from taproots. The stems are upright growing to a height of 30 to 120 cm. The flowers are sessile and produced in verticillasters. The calyx is tubular-campanulate shaped and 6-8 mm long with broad triangle shaped teeth. The corolla is white or reddish to purplish red in color. Plants bloom from June to September.[3]
It has escaped cultivation and become naturalized in other parts of the world including South and North America, Europe and Africa.
Uses[edit]
It is one of the 50 fundamental herbs used in traditional Chinese medicine, where it is called yìmǔcǎo (Chinese: 益母草), literally "beneficial herb for mothers".
In China, Leonurus heterophyllus injection has been studied for its potential to prevent postpartum hemorrhage after caesarian section.[4][unreliable source?]
