Herb latin name: Astragalus complanatus
Medicinal use of Astragalus complanatus:This species has been used for almost 2,000 years in China as a liver and kidney tonic. The seed is hepatic and ophthalmic. It is used in the treatment of kidney diseases, lumbago, spontaneous seminal emissions, frequent micturation, vertigo and decreased sight.
Description of the plant:
Habitat of the herb:Found at elevations of 1,000 - 2,400 metres in Anhui, Gansu, Henan, Jiangsu, Liaoning, Ningxia, Shaanxi and Sichuan provinces.
Propagation of Astragalus complanatus:Seed - best sown as soon as it is ripe in a cold frame. A period of cold stratification may help stored seed to germinate. Stored seed, and perhaps also fresh seed, should be pre-soaked for 24 hours in hot water before sowing - but make sure that you do not cook the seed. Any seed that does not swell should be carefully pricked with a needle, taking care not to damage the embryo, and re-soaked for a further 24 hours. Germination can be slow and erratic but is usually within 4 - 9 weeks or more at 13°C if the seed is treated or sown fresh. As soon as it is large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter, planting them out into their permanent positions in late spring or early summer, after the last expected frosts.
Cultivation of the herb:Found at elevations of 1,000 - 2,400 metres in Anhui, Gansu, Henan, Jiangsu, Liaoning, Ningxia, Shaanxi and Sichuan provinces.
Known hazards of Astragalus complanatus:Many members of this genus contain toxic glycosides. All species with edible seedpods can be distinguished by their fleshy round or oval seedpod that looks somewhat like a greengage. A number of species can also accumulate toxic levels of selenium when grown in soils that are relatively rich in that element.
