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.
Sea buckthorn berries are among the richest natural sources of vitamin C, along with beta-carotene and other carotenoids.
A distinctive fatty-acid profile, particularly rich in palmitoleic acid (omega-7), the basis of the oil's skin- and mucous-membrane-healing reputation.
Antioxidant flavonoids contributing to the plant's anti-inflammatory activity.

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).
Berries and juice are safe as food. Seed oil is safe topically and orally in moderate amounts. May have mild anticoagulant effects. May lower blood pressure and blood sugar — use caution with medications. Allergic reactions are rare.
Duke (2002) rates sea buckthorn as +++ and notes antioxidant, hepatoprotective, antiulcer, and vulnerary activities at the experimental level (score 1). The berries are exceptionally rich in vitamins C (one of the highest natural sources) and E, carotenoids, flavonoids, and omega-7 fatty acids (palmitoleic acid). Duke recommends sea buckthorn as a 'food farmacy' — consumed as part of the regular diet for its nutritional-medicinal benefits. Its radioprotective properties have been studied, though without strong clinical validation. No significant safety concerns at food doses (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]
Thorny, deciduous shrub or small tree with narrow, silvery-grey, willow-like leaves. The plant is dioecious (separate male and female plants); female plants bear dense clusters of small, bright orange-yellow berries tightly packed along the branches, giving a striking display in autumn.[4]
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.
Grows on coastal dunes, riverbanks and disturbed, nutrient-poor or sandy soils; native across temperate Europe and Asia, tolerant of harsh, exposed conditions and cold climates, notably widespread in the Himalayan and Tibetan plateau region.[4]
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-picked (often by cutting whole fruiting branches, given the thorns and fragile fruit) in late summer to autumn once ripe; leaves are picked through the growing season, and seeds are separated from pressed fruit for seed oil.[4]
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]
Sea buckthorn has a long Tibetan, Mongolian and traditional Chinese medicine history as a nutritive and healing tonic for respiratory, digestive and skin complaints, and the berries are exceptionally rich in vitamin C and carotenoids; the oil, from both fruit and seed, has a particular traditional and modern reputation for soothing and healing irritated or damaged skin and mucous membranes.[1, 4]
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.
Cold-pressed oil from the berry pulp or seed, applied topically for skin healing or taken orally as a nutritional/antioxidant supplement.
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.
