Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
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.

Safety, Cautions & Contraindications
Lower urinary tract / prostate symptoms must be medically assessed first to exclude prostate cancer. The evidence is mixed and rests on small, short, methodologically weak trials, so men with moderate or severe BPH should not rely on it instead of proven treatment.
Generally well tolerated, with mild gastrointestinal effects the most common report.
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
Evergreen tree (Rosaceae), 10-30 m tall, with dark, fissured, red-brown bark (the source of the common name 'red stinkwood', from its unpleasant smell when cut). Leaves are glossy dark green, leathery, oblong with finely toothed margins. Small white, five-petalled flowers are borne in axillary racemes, followed by small reddish-brown, two-lobed fruit.
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 montane forests of central and southern Africa (and Madagascar), growing at moderate to high altitude (roughly 900-3400 m). The species is CITES-listed and conservation-threatened owing to over-harvesting of bark for the pharmaceutical trade.
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
Bark is traditionally stripped from mature trees. Unsustainable stripping - especially removing bark all the way round the trunk - kills the tree and has driven population decline, so sustainable, partial and rotational bark harvesting or cultivated sources are recommended.
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
Prunus africana bark has a traditional use in East and Central African ethnomedicine for urinary complaints, and its extract (marketed as Pygeum) became one of the most widely used European phytotherapy remedies for benign prostatic hyperplasia (BPH) symptoms in the 20th century. Clinical evidence for symptom benefit is moderate but drawn from small, methodologically weak trials.[11]
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
The clinically studied commercial form, standardised for phytosterol content.
Dosage
Clinical trials have most often used around 100-200 mg/day of standardised lipophilic bark extract, divided into two doses. Educational reference only, not a prescription; any prostate or urinary symptom should be medically assessed first.
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.
