Key Constituents
Major bioactive saponin with cardio-, neuro-, hepato- and renoprotective effects.
Give the berries their deep colour and are the principal antioxidant constituents.
The fruit is exceptionally rich in vitamin C, contributing to its traditional cold/flu use.
The seed oil is a well-known plant source of the omega-6 fatty acid GLA.
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).
Supports resistance to colds and respiratory infection (immune)
Adaptogenic tonic for fatigue and low vitality (traditional 'Qi' tonic)

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.
Fruit (berries) • Generally safe as food for most people; adverse effects mainly GI discomfort or allergy in sensitive individuals. • If using high-dose extracts, use extra caution with blood-thinners/anticoagulants (evidence is not definitive, but polyphenol-rich supplements are often treated cautiously in practice). Leaf (folium) • EMA classifies blackcurrant leaf as a traditional herbal medicinal product (not “well-established use”): minor joint pain and urinary-tract flushing. • Typical label cautions (EMA-style): not recommended <18, avoid if you have edema due to impaired heart/kidney function, and seek medical advice if urinary symptoms persist/worsen. • Pregnancy/lactation: food use is fine, but medicinal leaf dosing is generally used cautiously due to limited robust safety data. Seed (seed oil) • Usually well tolerated, but may cause GI upset in some people. • Caution with anticoagulants/antiplatelet drugs (PUFA supplements are often used cautiously here). • Note: some trials explored maternal/infant contexts, but that does not automatically mean “recommended in pregnancy” outside medical supervision.
Duke (2002) rates blackcurrant fruit highly (+++), with evidence for anti-inflammatory, angioprotective, and antioxidant activities. Ribes nigrum extracts showed the richest anthocyanin and polyphenol content in antioxidant studies, outperforming many other common berries. Clinical use is supported for diarrhea, colds, and flu. The high vitamin C and anthocyanin content underpin its vasoprotective effects. The fruit is treated as food-grade medicine and is classified as generally safe (Duke, 2002).

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]
Deciduous shrub (Grossulariaceae), 1-2 m tall, aromatic when the leaves are crushed. Leaves are palmately lobed (3-5 lobes), toothed, with resinous glands on the underside. Small, greenish-white to dull purple, bell-shaped flowers are borne in drooping racemes, followed by clusters of glossy black berries.
Habitat
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]
Native to central and northern Europe and Siberia, growing in damp woodland, fens, riverbanks and hedgerows; widely cultivated commercially as a fruit crop in cool-temperate climates.
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]
Berries are hand- or machine-harvested in mid- to late summer once fully ripe and black. Leaves are gathered in late spring to early summer, before flowering fades, for the medicinal leaf preparation. Seed oil is cold-pressed from the seeds after juicing.
Traditional Uses
Blackcurrant has a long northern-European food-medicine tradition: the vitamin-C- and anthocyanin-rich berries have traditionally been used for colds, flu and general vitality, while the leaf has an official EU traditional-use registration for minor joint pain and as a urinary-tract flush, and the seed oil is valued as a source of gamma-linolenic acid (GLA). Modern research confirms broad antioxidant, anti-inflammatory, immunomodulatory and vasoprotective activity across the fruit, leaf and seed oil.[11, 12, 13]
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.
EMA-style traditional-use guidance for the leaf suggests roughly 2-4 g dried leaf per cup as an infusion, up to three times daily, for short-term joint or urinary support (not recommended under 18, or with fluid retention linked to heart/kidney disease). Berries and juice are food-safe at normal dietary amounts. Educational reference only, not a prescription.
