Astragalus is a plant with “magical” properties that have been attributed to it in traditional medicine, particularly Chinese medicine, including the promotion of longevity and protection from negative influences. These reputed properties are linked to its tonifying, adaptogenic and immune-stimulating effects, which are said to strengthen “Qi” (vital energy) and “Wei Qi” (defensive energy).

Its roots contain polysaccharides, saponins and flavonoids that stimulate immune cells such as macrophages and lymphocytes, strengthen the body’s defences, and help counter infections of the respiratory tract while reducing oxidative stress and lung fatigue.
