Chinese motherwort is unusual amongst Chinese herbs in that it is often prescribed for use on its own and not in a mixture with other plants[238]. The whole plant is antibacterial, antispasmodic, astringent, cardiac, depurative, diaphoretic, diuretic, emmenagogue, hypnotic, nervine, oxytocic, stomachic, tonic, uterine stimulant[4, 9, 21, 46, 165, 174, 178, 192, 279]. The seeds have a similar action to the plant, but are a less effective diuretic and depurative[238]. The plant is used in the treatment of painful and excessive menstruation, post-partum bleeding, oedema, kidney complaints, kidney stones, eczema and abscesses[238, 240]. A tincture is used in the treatment of rheumatic fever[192]. The plant stimulates uterine contractions and should not therefore be used when in the earlier stages of pregnancy[240]. The plant is harvested when in flower but before the seeds have set, and is dried for later use[238]. The plant contains about 0.05% of an alkaloid called leonurine[240]. This has a curare-like effect on the motor-endings of the nervous system, acting in small doses as a stimulant to the respiratory system but in large doses causing respiratory paralysis[240].
Other Uses
Essential.

Yields an essential oil[46]. No more details are given.
Cultivation details
Prefers a well-drained moist soil in sun or partial shade[238]. Prefers a poor soil[108]. Plants are hardy to at least -15°c[238]. There is some confusion over the correct name for this species, it should quite probably be called L. japonicus.
Propagation
Seed - sow late spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
