Women's complaints

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[218]. The leaves are diuretic and are placed in bath water to relieve itching and painful shingles[218]. The dried flowers are emmenagogue and are also used in pregnancy and to help expel the placenta after giving birth[218]. The juice of the stems is vulnerary[218]. The fruit is antibacterial, diuretic, emmenagogue, hypotensive, ophthalmic and vasodilator[176, 218]. It is used in the treatment of abnormal menstruation, nebula and conjunctivitis[176]. The seed is aphrodisiac, diuretic, emmenagogue, ophthalmic and is also used in the treatment of various women's complaints[147, 218]. The plant was ranked number one in a survey of 250 potential antifertility plants in China[218]. The seed is used in the treatment of conjunctivitis and night blindness[147]. The aerial parts of the plant are alterative, antibacterial, antifungal, depurative, diuretic, emmenagogue, hypotensive, vasodilator and vulnerary[176, 218]. The whole plant is decocted, either on its own or with other herbs, as an ophthalmic[218]. It is used in the treatment of abnormal menstruation, postpartum abdominal pain, tumours, uterine bleeding, oedema, eczema and purulent abscess[176]. It is also used externally as a poultice for bruises[218]. Stimulates blood circulation[147]. (The part of the plant used is not made clear.)

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cultivation details

We have almost no information on this species and do not know if it will be hardy in this country. The following notes are based on the general needs of the genus. Succeeds in most soils[200]. Prefers a poor soil[108]. 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[218].
