Astragalus mongholicus, synonyms including Astragalus propinquus and Astragalus membranaceus,[1] commonly known as Mongolian milkvetch in English;[2] 'Хунчир' in Mongolian; huáng qí (Chinese: 黃芪), běi qí (Chinese: 北芪) or huáng huā huáng qí (Chinese: 黃花黃耆),[3] in Mongolia, is a flowering plant in the family Fabaceae.

[5] A. mongholicus is widespread in temperate Asia, being found in Kazakhstan, from Siberia to the Russian Far East, in Mongolia, and in west and north China.

[6] A. mongholicus is a component in Lectranal, a food supplement used in treatment of seasonal allergic rhinitis,[7] though there is limited evidence of its effectiveness.

[8] 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.

While several other species of Astragalus are known to cause severe poisonings in livestock due to indolizine alkaloids, aliphatic nitro compounds, and accumulated selenium,[11] none of these constituents have been detected in Astragalus mongholicus used in dietary supplements and TCM preparations.
