Key Constituents
The principal bioactive triterpene saponins of the root, considered responsible for most of ginseng's adaptogenic, neuroprotective and immunomodulatory activity; the ratio of protopanaxadiol- to protopanaxatriol-type ginsenosides differs between fresh, white and red ginseng.
Contribute to the immunomodulatory activity of the root.
Minor constituents contributing to the aroma and antioxidant activity.
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
Generally well tolerated in short-term use (up to 3 months). May cause insomnia, headache, or gastrointestinal upset at high doses. Avoid during pregnancy and breastfeeding. May interact with warfarin, MAOIs, and diabetic medications. Not recommended for continuous use without breaks.
Duke (2002) rates Korean/Oriental ginseng (Panax ginseng) as highly active with clinical support for adaptogenic, immunostimulant, and performance-enhancing effects. Commission E approves standardized ginseng root extract (4–7% ginsenosides) as a tonic for fatigue and during convalescence. Dose: 200–600 mg standardized extract daily. Duke cautions about 'Ginseng Abuse Syndrome' (GAS) with overdose — symptoms include hypertension, insomnia, edema, and nervousness. Drug interactions are notable: ginseng potentiates MAOIs and may interact with warfarin, digoxin, and stimulants. Cycle use (2–3 weeks on, 2 weeks off) is recommended (Duke, 2002).
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
Slow-growing perennial herb (Araliaceae), 30-60 cm tall, harvested at 4 years of age or older. A single erect stem bears a whorl of palmately compound leaves, each with 3-5 toothed leaflets, at its top. Small greenish-white flowers are borne in a single terminal umbel, followed by small red berries. The fleshy, often forked or human-shaped taproot - the origin of the name 'ginseng' ('renshen', man-root) - is the medicinal part.[3]
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 cool-temperate deciduous mountain forests of Manchuria, Korea and the Russian Far East. Historically wild-harvested, it is now predominantly cultivated, mainly in Korea and China, under artificial shade for several years before harvest.[1]
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 harvested after at least 4-6 years of growth, once its ginsenoside content is fully developed. Roots are either air-dried as 'white ginseng' or steamed and then dried as 'red ginseng', a processing step that alters the ginsenoside profile.[3]
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
Ginseng is one of the most celebrated tonic herbs of East Asian traditional medicine, used for millennia as a general adaptogen to restore vitality, support recovery from illness and improve stamina and cognitive performance. Modern clinical research supports adaptogenic, immunomodulatory, antioxidant, neuroprotective and mild antidiabetic effects consistent with this traditional use.[1, 7]
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
Commission E-recognised standardised extract (4-7% ginsenosides), the most clinically studied preparation.
Traditional processed form (steamed then dried), which alters and concentrates the ginsenoside profile compared with white (unprocessed) ginseng.
Dosage
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.

Pairings
Ginseng and feverfew both reduce blood clotting/platelet stickiness, so taking them together may add up and raise the risk of bruising or bleeding — use caution, especially before surgery or alongside blood-thinning drugs.[19, 20]
