Radix Astragali
The great Qi builder and Wei (defensive) energy fortifier — Astragalus membranaceus strengthens the Spleen, secures the body's surface, and raises the energy of life.

What Is Radix Astragali?
Radix Astragali (黄芪, Huáng Qí) is the dried root of Astragalus membranaceus, one of the most important tonic herbs in the entire Chinese materia medica and one of the most extensively researched traditional medicinal plants in modern science. Sweet and slightly warm, it acts primarily on the Spleen and Lung channels to tonify the Middle Qi, raise Spleen-Stomach energy, and fortify the Wei Qi (defensive Qi) that circulates at the body's surface to protect against external pathogenic invasion. It is considered the foremost herb for consolidating the Exterior and is indispensable in conditions of Qi deficiency with spontaneous sweating.
Astragalus has a remarkable range of clinical applications extending from simple fatigue and poor digestion to prolapse, non-healing wounds, oedema, and deficiency fevers. In modern integrative medicine, it has become one of the most popular immune-supporting botanical adaptogens, with clinical research demonstrating immunomodulatory, anti-inflammatory, antioxidant, antiviral, cardioprotective, and anti-ageing effects. Astragalosides — particularly astragaloside IV — have attracted significant interest for their telomerase-activating activity, suggesting potential applications in cellular longevity.
History & Origin
Astragalus root has been elevated to the highest rank of tonic herbs throughout Chinese medical history, consistently praised across dynasties for its ability to strengthen the life force, secure the exterior, and restore depleted energy in the young and old alike.
