Uses
Astragalus may help support the immune system, according to RxList. In Chinese medicine, the tonic form is used to treat conditions such as diabetes -- by lowering blood sugar levels -- and kidney infections. The root may help boost the immune systems of individuals with compromised immune systems from a virus, such as HIV, or during recovery from chemotherapy, according to the National Center for Complementary and Alternative Medicine. The herb may also help treat heart disease and upper airway infections, such as the common cold. Astragalus may help treat constipation, thanks to its laxative effect.
Availability and Dosage
The root is available as a single, long piece; shredded; in powdered form; as a tincture; or as a capsule. Although there are no set dosage guidelines, a typical dose of astragalus is two to six doses each day, according to Drugs.com. You can add the root to tea or soup. Drink plenty of fluids when taking astragalus because of the risk of dehydration related to increased urine output.
Safety Concerns
If you have a medical condition involving the immune system, do not take Astragalus membranacus without speaking to your doctor first. Those with autoimmune conditions such as lupus, rheumatoid arthritis or multiple sclerosis, and organ transplant recipients may experience an increase in activity involving the immune system that can worsen their conditions. Women who are pregnant or breastfeeding should not take Astragalus.
Medication Interactions
Astragalus may affect other medications used to suppress the immune system, such as prednisone or cyclosporine. Astragalus may decrease the effectiveness of these immunosuppressants, according to Drugs.com. Astragalus may increase urine output and may decrease the ability to excrete lithium. Individuals taking lithium should speak with a physician before taking Astragalus.
