Astragalus

Also called: Huang qi, Astragalus membranaceus

A root from traditional Chinese medicine used to strengthen the immune system and support energy. It is usually taken to prevent illness rather than during an acute infection.

Supplements can interact with medications and aren't right for everyone, especially during pregnancy or breastfeeding, or with a chronic condition. Ask your provider before you start.

Blood & immune system

Blood carries oxygen and nutrients, and white blood cells defend you from infection. In autoimmune disease, that defense system targets your own tissues.
