Botanical Description

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]

Height: 1-6 m (occasionally to 10 m)
Habit: Thorny, deciduous, dioecious shrub or small tree
Leaves: Narrow, silvery-grey, willow-like
Flowers: Small, inconspicuous, wind-pollinated, on separate male and female plants
Stem: Thorny, much-branched
Root: Extensive, nitrogen-fixing root system with suckering growth
Fruit: Small, bright orange-yellow berry, densely clustered along the branches (female plants only)
Flowering Period: Early spring, before leaf-out

Habitat & Distribution

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

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]

Parts: Fruit, Leaf, Seed
Season: Fruit in late summer to autumn; leaf through the growing season

Key Constituents

Vitamin C and carotenoids[4]

Sea buckthorn berries are among the richest natural sources of vitamin C, along with beta-carotene and other carotenoids.

Carotenoids
Omega-7 fatty acids (palmitoleic acid)[4]

A distinctive fatty-acid profile, particularly rich in palmitoleic acid (omega-7), the basis of the oil's skin- and mucous-membrane-healing reputation.

Flavonoids[1]

Antioxidant flavonoids contributing to the plant's anti-inflammatory activity.

Traditional Use & History

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

Fruit/seed oil[4]

Cold-pressed oil from the berry pulp or seed, applied topically for skin healing or taken orally as a nutritional/antioxidant supplement.

Safety, Cautions & Contraindications

Safety note[16, 17, 18]Caution

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.

Safety note[16, 17, 18, 19]Info

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).

Harvest Readiness

[15]

Part: fruit
Signals: Harvest the berries when ripe from autumn (late September on), before frost degrades them - the fruit hangs on through winter but frosted berries deteriorate quickly.
Basis: traditional
Source Quote: The fruit is ripe from late September and usually hangs on the plants all winter if not eaten by the birds.
Species Confirmed: 1
Notes: PFAF (REF-3268); the berries ripen from late September and persist over winter, but are best gathered before frost ('the taste and quality of frosted berries quickly deteriorates'). Single lineage -> provisional.

[15]

Part: seed
Signals: Collect the seeds when the fruit ripens in autumn.
Basis: traditional
Source Quote: The seeds ripen from September to October.
Species Confirmed: 1
Notes: PFAF (REF-3268); the seeds ripen in autumn (September-October). Single lineage -> provisional. (The leaf, also a listed part, was not separately timing-sourced this pass.)
