Synopsis of astragalus

Astragalus (Astragalus membranaceus) is a perennial herb in the Fabaceae (legume) family, native to northern and eastern China, Mongolia, and Korea. Known as Huang Qi in Traditional Chinese Medicine (TCM), the root is the primary medicinal part and is widely used for its immune-boosting, adaptogenic, and qi-tonifying properties. It is considered one of the top herbs for strengthening the body’s defenses, especially when dealing with chronic weakness, fatigue, or immune compromise.

Astragalus contains polysaccharides (especially astragalans), saponins (astragalosides), flavonoids, and trace minerals that contribute to its wide-ranging effects. It is best known for its ability to:

  • Enhance immune function (by stimulating macrophages, T-cells, and natural killer cells)
  • Increase resistance to stress and fatigue
  • Support cardiovascular health
  • Improve kidney function
  • Promote wound healing and tissue regeneration
  • Balance inflammation and oxidative stress

In integrative and functional medicine, astragalus is often included in protocols for immune support during chronic illness, adrenal resilience, post-viral fatigue, or preventive care during cold and flu season. It is most effective when taken consistently over time as a tonic, and is available in capsules, teas, tinctures, extracts, or sliced root for decoctions.

Historical Use:

Astragalus has been used for over 2,000 years in Traditional Chinese Medicine, where it is categorized as a superior tonic herb. It is traditionally used to tonify the Spleen and Lung qi, raise yang energy, and strengthen the exterior to protect against invasion by external pathogens (such as wind-cold or wind-heat). It is also believed to promote the discharge of pus and generate flesh, making it useful in both internal and topical wound-healing applications.

In classic formulas like Yu Ping Feng San (Jade Windscreen Powder), astragalus is combined with fang feng and bai zhu to fortify the body's surface and protect against seasonal illness. It is also included in convalescent formulas to help restore vitality after long illness or surgery.

Though less known in Western herbal traditions, astragalus has gained popularity in recent decades for its adaptogenic and immune-modulating properties, making it a mainstay in modern herbal protocols aimed at building resilience, balancing immune response, and supporting long-term vitality.

Today, astragalus remains one of the most versatile and respected herbs for strengthening immunity, increasing energy, and protecting the body against chronic stress, environmental insults, and age-related decline.
