It mainly refers to the basis of Achyranthes bidentata Blume., a bulb in
the ancestors Amaranthaceae. Hence, its accepted names cover Achyranthis
bidentatae radix, basis achyranthis bidentatae, achyranthes bidentata root,
basis achyranthis, and so on. Medicinally it primarily comes from cultivation.
The agriculture time is in winter if the bulb is withered. Afterwards that,
apple-pie it with water, dry it in the sun, and use it raw or stir-fried with
wine. It’s important to agenda that the basis of Cyathula officinalis Kuan
(Chuan Niu Xi) and Achyranthes aspera (Tu Niu Xi) is agnate medicinally. But
these three herbs are altered and it needs to analyze a allotment of them
clinically.

20cm (including axis on the lower part). Utricle is ellipsoidal and smooth.
Brown berry is 1 alone in number. And its beginning aeon is from July to
September and fruiting aeon is from September to October.
Main actinic capacity are triterpenoid saponins (including oleanolic
acerbic and amoroso afterwards hydrolysis), steroid compositions (ecdysterone,
inokosterone, and rubrosterone), a array of polysaccharides, 12 kinds of amino
acids like glycine, alkaloids, coumarins compounds, and trace elements like
iron, copper, and more.
