Botanical Description

A perennial member of the pea family with compound pinnate leaves of small oval leaflets, loose racemes of small pale yellow pea-like flowers, and a long fibrous taproot with a pale yellow interior used medicinally.

Also known as: Huang Qi, Milk Vetch, Yellow Leader

Historical Background

Astragalus (huang qi, 'yellow leader') has been one of the most important Qi-tonifying herbs of Traditional Chinese Medicine for over 2,000 years, prized for vitality, defense, and stamina. Its sliced root is simmered long into nourishing soups and teas, often with jujube, goji, and ginger, to support convalescence and seasonal resilience.

Earliest recorded uses: Recorded in the Shennong Ben Cao Jing (~2000 years ago) as a superior Qi tonic; a pillar of TCM.

Modern Evidence

Astragalus is a pillar of TCM as a Qi and immune tonic. Clinical evidence is limited; some trials (often combined with other herbs) suggest possible immune and fatigue benefits, but it is not a treatment for cancer, infection, or any disease, and interacts with immune-suppressive therapy.
