Astragalus appears to work by stimulating the immune system. It has antioxidant effects that inhibit free radical production. In the body, free radicals damage cells and are linked to many health problems associated with aging.

Astragalus contains three components that allow the plant to have such a positive impact on human health: saponins, flavonoids and polysaccharides, which are all active compounds contained in certain plants, including some fruits and vegetables. Saponins are known for their ability to lower cholesterol, improve the immune system and prevent cancer. Flavanoids, also found in astragalus, provide health benefits through cell signaling. They show antioxidative qualities, control and scavenge of free radicals, and can help prevent heart disease, cancer and immunodeficiency viruses. Polysaccharides are known to have antimicrobial, antiviral and anti-inflammatory capabilities, among other health benefits.

Astragalus root should only be given to a child under your healthcare provider's direct supervision, and it should never be given to a child with a fever. The University of Maryland Medical Center states that the pediatric dosage is calculated using the standard adult dosage based on a 150-lb. individual. For example, a child weighing 50 lbs. would take 1/3 the adult dosage, and a child weighing 35 lbs. would take about 1/4 the adult dose.
