Key Constituents
Leaf essential oil dominated by 1,8-cineole (eucalyptol, typically 70%+), the principal compound responsible for the plant's antimicrobial, anti-inflammatory and expectorant/decongestant 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
Eucalyptus globulus essential oil is highly concentrated and rich in the monoterpene 1,8-cineole; it should never be applied undiluted to the skin or ingested outside of standardized pharmaceutical preparations. Improper use can cause irritation, nausea, dizziness, or neurological symptoms, and inhalation at high concentrations may provoke respiratory distress, particularly in infants, young children, or individuals with asthma or other airway sensitivities. For this reason, essential oil use is generally discouraged in children and during pregnancy unless under professional guidance. Preparations such as leaf-infused oils or external applications using whole plant material are considerably milder, but they should still be used with care and an understanding that different preparation methods carry different levels of risk.
Duke (2002) provides clinical evidence (score 2) for eucalyptus as an expectorant and topical hyperemic (rubefacient), consistent with Commission E approval. Clinical evidence also supports its use in asthma, bronchitis, and catarrh. The essential oil (primarily 1,8-cineole) is the active constituent. Therapeutic use as steam inhalation is well-established. Internal use of the essential oil at high doses is contraindicated due to toxicity; even small amounts (3.5 ml) can be fatal in children. Contraindicated for inflammatory diseases of the gastrointestinal tract or bile ducts (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
Large, fast-growing evergreen tree with distinctive two-stage leaves: rounded, silvery-blue juvenile leaves borne in opposite pairs, giving way to narrow, sickle-shaped, aromatic, dark green mature leaves as the tree ages. Small, cream-white, fluffy flowers with numerous stamens are borne singly or in small clusters, followed by a woody, cup-shaped seed capsule ('gum nut').[12]
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 south-eastern Australia and Tasmania; widely planted worldwide in warm-temperate and Mediterranean climates for timber, essential oil production and as an ornamental/windbreak tree.
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
Mature leaves are picked or pruned year-round and used fresh, dried, or steam-distilled for essential oil, which is the main commercial and medicinal form.
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
Eucalyptus leaf has a long Australian Aboriginal and, after global spread, worldwide tradition as a respiratory remedy - inhaled as steam or applied as chest rubs for colds, coughs, bronchitis and catarrh - and as a topical antiseptic and rubefacient for minor wounds and muscular aches.[12]
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
A few drops of essential oil, or fresh/dried leaf, added to hot water and the vapour inhaled for respiratory congestion; the classic and best-established use.
Diluted essential oil in a carrier oil or standardised ointment applied to the chest and back for coughs and colds.
Comminuted dried leaf infused in 150 ml boiling water, 1.5-3 g up to four times daily (daily dose 4.5-12 g) for oral use per the EU herbal monograph. Educational reference only, not a prescription.
Dosage
The EU herbal monograph on eucalyptus LEAF gives, for inhalation, 3 g of the comminuted leaf in boiling water up to 3 times daily (daily dose 3-9 g), and for oral use 1.5-3 g in 150 mL as an infusion up to 4 times daily (daily dose 4.5-12 g), in adolescents, adults and elderly. Use is CONTRAINDICATED in children under 30 months, and not recommended under 12 years. The essential oil is a separate herbal substance with its own monograph and its own posology - it is never taken internally or applied undiluted to skin on the strength of these leaf figures. 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.
