- Astragalus products are derived from the roots of Astragalus membranaceus or related species, which are native to China. In traditional Chinese medicine, astragalus is commonly found in mixtures with other herbs, and is used in the treatment of numerous ailments, including heart, liver, and kidney diseases, as well as cancer, viral infections, and immune system disorders. Western herbalists began using astragalus in the 1800s as an ingredient in various tonics. The use of astragalus became popular in the 1980s based on theories about anti-cancer properties, although these proposed effects have not been clearly demonstrated in reliable human studies.
- Some medicinal uses of astragalus are based on its proposed immune stimulatory properties, reported in preliminary laboratory and animal experiments, but not conclusively demonstrated in humans. Most astragalus research has been conducted in China, and has not been well designed or reported.
- Gummy sap (tragacanth) from astragalus is used as a thickener in ice cream, an emulsifier, a denture adhesive, and an anti-diarrheal agent.
