百合科黄精属多年生草本，根状茎呈不规则的连珠状或圆柱状。高30－90cm。叶3－6枚轮生，狭线形至线状披针形，先端弯曲成钩状。花序腋生，常有2花；花被淡紫色。浆果红色或紫红色，直径约9mm。花期5－6月，果期8－9月。　　喜凉润，极耐寒，耐干燥瘠薄。产西藏南部、中部至东南部的广大地区，多生于海拔2400－4800m的林缘或林中、山坡草地或荒地上。西南、西北以及沿喜马拉雅诸国也产。西藏还产轮叶黄精与前者相近，区别为叶先端不卷曲；分布较之更广。这两种黄精的根茎均能入药，有补牌润肺、益气养阴的功效。

Perennial herb of the genus *Polygonatum* (family Liliaceae), with rhizomes irregularly moniliform or cylindrical. Height 30–90 cm. Leaves in whorls of 3–6, narrowly linear to linear-lanceolate, apex curved into a hook. Inflorescences axillary, usually bearing 2 flowers; perianth pale purple. Berries red or purplish red, approximately 9 mm in diameter. Flowering period: May–June; fruiting period: August–September. It prefers cool and moist habitats, is extremely cold-tolerant, and tolerates dry and barren soils. It is widely distributed in southern, central to southeastern Tibet, mostly growing in forest margins, forests, slope grasslands or wastelands at elevations of 2400–4800 m. It also occurs in southwest and northwest China, as well as countries along the Himalayas. In Tibet, *Polygonatum verticillatum* is also distributed, which is similar to the aforementioned species, differing in that its leaf apices are not curved and has a wider distribution range. The rhizomes of both Polygonatum species are used in traditional Chinese medicine, with the effects of invigorating the spleen, moistening the lung, replenishing qi and nourishing yin.
