Ethnobotany

Haiershen is a relatively recent addition to the Chung Yao Chi New Chinese Materia Medica (Chinese: 中藥劑大辭典), having been officially added in 1959, based upon local and ethnic use.[1][2] It is weaker than Panax ginseng. The herb is a mild adaptogen, demulcent, an immune tonic, nutritive, and a pectoral herb. In Chinese terms it tonifies the yin. Accordingly, the herb is restorative for lung damage due to excess heat or dryness including hot or dry asthma, pleurisy, bronchitis, bacterial pneumonia, wheezing, dry cough, and emphysema. Scientific research shows that this Pseudostellaria aids in protecting the mucin layer that lines the respiratory tract and functions as an immune defense system. In the form Li Gan Zi Shen Tang (Chinese: 理肝滋腎湯, "Regulate the Liver & Enrich the Kidneys Decoction") it is used to treat yin deficiency associated with diabetes mellitus.[3] The polysaccharide fractions have in vitro anti-tumor properties.[4] A lectin in the roots is being studied for anti HIV purposes.[5]

This is a perennial herb with tubers and solitary erect stems up to 20 centimeters tall.

The flower has 5 white petals, but some flowers are cleistogamous and lack petals.[6]

gollark: <@!221827050892296192> They used to actually be represent size of the transistors involved, but they no longer do, so the names are basically just, er, "generations" of process technology.
gollark: Don't think so.
gollark: (apart from some 1st gen ones apparently produced on 12nm for some reason? There are apparently a bunch of weird ones in the wild)
gollark: No, 1st gen is 14nm and 2nd gen is 12nm.
gollark: The chipsets are still not 7nm, right? As well as the 1st/2nd gen ones they still seem to sell (they're available very cheaply, at least) and some mobile CPUs.
