Astragalus propinquus (syn. Astragalus membranaceus[2] also known as huáng qí (Chinese: 黄芪), běi qí (Chinese: 北芪) or huáng huā huáng qí (Chinese: 黄花黄耆),[3] is a flowering plant in the family Fabaceae.

Herbalism

A. propinquus is used in traditional Chinese medicine for healing and for diabetes.[5]

Related species

The natural gum tragacanth, which is used in pharmaceuticals and textiles, is obtained from Astragalus tragacanthus.[6]

Medical

A. propinquus is an component in Lectranal, a food supplement used in treatment of seasonal allergic rhinitis.[7][8]

Chemistry

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.[9] It contains the saponin cycloastragenol. Constituents of the roots (Radix Astragali) include polysaccharides, triterpenoids (astragalosides)[10] as well as isoflavones (including kumatakenin, calycosin and formononetin) along with their glycosides and malonates.[11]

Toxicology

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 the medicinal species Astragalus membranaceus used in dietary supplements and TCM preparations.[13]

Compendial status

A. propinquus is listed in the following official Pharmacopeia:
