Leonurus japonicus, commonly called oriental motherwort[3] or Chinese motherwort, is a herbaceous flowering plant native to Asia, including Korea and Japan, and China to Cambodia.

Description[]

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.[4]

It has escaped cultivation and become naturalized in other parts of the world including South and North America, Europe and Africa.

Uses[]

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". It is used in cases of menstrual and delivery disorders caused by blood stasis, like dysmenorrhea, and amenorrhea.[5]

Leonurus japonicus, contains several compounds with biology activity, such as guanosine (CAS: 118-00-3), rutin (CAS: 153-18-4), syringic acid (CAS: 530-57-4) and stigmasterol (CAS: 83-48-7). Scientists use the purified compound as a standard in drug screening.[6]
