The "immune powerhouse" of TCM, this extract hails from Gansu and Inner Mongolia’s arid lands—where harsh conditions forge astragalus with high astragaloside IV content. Revered for "strengthening the body’s resistance," modern research validates its role in boosting immunity and protecting cardiovascular health. It is used in pharmaceuticals, supplements, and functional foods worldwide, with global demand exceeding 120,000 tons annually. 

China’s dominance in production ensures stability, and its role in immune health will remain critical post-pandemic.
