Medicinal uses(Warning!)

This plant (and other closely related species) is commonly used in Chinese herbalism, where it is considered to be one of the 50 fundamental herbs[1].

The leaves are diuretic and are placed in bath water to relieve itching and painful shingles[1]. The dried flowers are emmenagogue and are also used in pregnancy and to help expel the placenta after giving birth[1]. The juice of the stems is vulnerary[1]. The fruit is antibacterial, diuretic, emmenagogue, hypotensive, ophthalmic and vasodilator[2][1]. It is used in the treatment of abnormal menstruation, nebula and conjunctivitis[2]. The seed is aphrodisiac, diuretic, emmenagogue, ophthalmic and is also used in the treatment of various women's complaints[3][1]. The plant was ranked number one in a survey of 250 potential antifertility plants in China[1]. The seed is used in the treatment of conjunctivitis and night blindness[3]. The aerial parts of the plant are alterative, antibacterial, antifungal, depurative, diuretic, emmenagogue, hypotensive, vasodilator and vulnerary[2][1]. The whole plant is decocted, either on its own or with other herbs, as an ophthalmic[1]. It is used in the treatment of abnormal menstruation, postpartum abdominal pain, tumours, uterine bleeding, oedema, eczema and purulent abscess[2]. It is also used externally as a poultice for bruises[1].

Stimulates blood circulation[3]. (The part of the plant used is not made clear.)

Succeeds in most soils[4]. Prefers a poor soil[5].

There is some doubt over the correct name for this species, a recent work suggested that it should be L. artemisia (Lour.)S.Y.Hu. - at least in as much as it refers to the medicinal plant in China[1].
