Description
Astragalus is a hardy perennial legume native to northern and eastern China, Mongolia, and Korea. The plant grows approximately 1–4 feet (0.3–1.2 m) in height and bears pinnate leaves, pale yellow flowers, and seed pods characteristic of the pea family. The medicinal root is harvested from mature plants, typically after four to seven years of growth. The dried root is yellowish, fibrous, and slightly sweet.
History & Tradition
Historical Overview
Astragalus has been used in Traditional Chinese Medicine (TCM) for over two thousand years and is considered one of the most important tonic herbs in the Chinese materia medica. The name Huang Qi translates roughly as "Yellow Leader" or "Yellow Chief," referring both to the color of the root and its esteemed position among tonic herbs.
Historically, Astragalus was used to strengthen Wei Qi (Defensive Qi), support vitality, assist recovery from illness, and promote endurance. It appears in numerous classical Chinese formulas and remains one of the most frequently prescribed herbs in modern TCM practice.
Astragalus was introduced to Western herbalism relatively recently compared to many European herbs but has become highly regarded among contemporary clinical herbalists for its tonic and adaptogenic properties.
Mrs. M. Grieve Notes
Astragalus is not discussed in A Modern Herbal, as it was not a commonly used medicinal herb in early twentieth-century Western herbal practice.
