Botanical Description
Erect perennial herb with a long, fibrous, pale yellow taproot. The leaves are pinnately compound with numerous small, oval leaflets, giving a soft, ferny appearance. Small, pale yellow, pea-like flowers are borne in loose axillary clusters (racemes), followed by membranous, inflated seed pods that give the species its name.[5]
Habitat & Distribution
Native to the grasslands, sunny slopes and forest margins of northern and north-eastern China, Mongolia and parts of Korea; widely cultivated as a medicinal crop across East Asia.[5]
Harvesting
The root is dug from plants at least four years old, typically in spring or autumn, then cleaned and dried, often sliced into the characteristic pale, fibrous 'coin' slices used in traditional decoctions.[5]
Key Constituents
Pharmacological Actions
Astragalus membranaceus and its constituents (astragaloside IV, cycloastragenol, Astragalus polysaccharide) inhibit tumour growth, invasion and metastasis and enhance antitumour immunity across lung, colorectal and gastrointestinal cancers (preclinical, incl. in vivo).
Immune support / immunomodulation (activates macrophages, NK cells, T and B lymphocytes)
Traditional & Indicated Uses
inferred from anti-inflammatory action
Astragalus membranaceus protects against gastrointestinal cancers; astragaloside IV inhibits lung cancer metastasis via macrophage repolarization, cycloastragenol boosts CD8+ T-cell antitumour immunity (with anti-PD-1 synergy), and Astragalus polysaccharide suppresses inflammation-induced colorectal cancer (preclinical).

Traditional Use & History
Preparations
Dosage
The WHO monograph on Radix Astragali gives doses of 3-9 g per day. Traditional Chinese medicine references often cite a considerably higher 9-30 g of dried root per day; WHO's figure is the conservative regulatory-tier one and is stated here in preference. Educational reference only, not a prescription.
Clinical studies commonly use extracts providing the equivalent of several grams of dried root daily, in divided doses. Educational reference only, not a prescription.
Safety, Cautions & Contraindications
Astragalus stimulates immune activity; on theoretical grounds it should be used cautiously in autoimmune disease and with immunosuppressant medicines (for example after organ transplant) - discuss with a clinician.
Generally well tolerated; high-quality long-term human safety and toxicity data remain limited.
Safety in pregnancy and breastfeeding has not been established; avoid medicinal doses.
