Astragalus propinquus (syn. Astragalus membranaceus,[2] commonly known as Mongolian milkvetch[3] in English and as huáng qí (Chinese: ), běi qí (Chinese: ) or huáng huā huáng qí (Chinese: 黄花黄耆),[4] in Chinese, is a flowering plant in the family Fabaceae. It is one of the 50 fundamental herbs used in traditional Chinese medicine.[5] It is a perennial plant and it is not listed as being threatened.[1]

Herbalism[edit]

A. propinquus is used in traditional Chinese medicine (TCM).[6] A. propinquus is an component in Lectranal, a food supplement used in treatment of seasonal allergic rhinitis,[7] though there is limited evidence of its effectiveness.[8]

Chemistry[edit]

Chemical constituents of the roots (Radix Astragali) include polysaccharides and triterpenoids (such as astragalosides),[9] as well as isoflavones (including kumatakenin, calycosin, and formononetin) and their glycosides and malonates.[10] An extract of A. propinquus called TA-65 may activate telomerase, extending the lengths of the shortest telomeres which protect the terminal DNA at the ends of all chromosomes.[11] It contains the saponin cycloastragenol.

Toxicology[edit]

While several other species of Astragalus are known to cause severe poisonings in livestock due to indolizine alkaloids, aliphatic nitro compounds, and accumulated selenium,[12] none of these constituents have been detected in Astragalus propinquus used in dietary supplements and TCM preparations.[13]

Compendial status[edit]

A. propinquus is listed in the following official Pharmacopeia:

  • Japanese Pharmacopoeia[14]
