Key Constituents
Borage seed oil has one of the highest known GLA contents of any plant oil (typically 20-26%), the basis of its anti-inflammatory reputation.
Unsaturated pyrrolizidine alkaloids present in the whole herb are hepatotoxic and genotoxic on cumulative exposure, limiting internal whole-herb use; the refined seed oil is largely free of them.
Contribute to the plant's traditional demulcent and astringent properties.
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
Pyrrolizidine alkaloids (PAs): Many Boraginaceae can produce PAs; unsaturated PAs are hepatotoxic and genotoxic (risk increases with cumulative exposure). Borage as food/tea: PA presence in borage consumed as herb/tea has been specifically studied; EU has set PA maximum levels for certain foods including borage (context for why sourcing/limits matter). Pregnancy/breastfeeding: avoid internal use of borage herb products due to PA-related concerns and risk uncertainty. Liver disease / long-term use: avoid (PA risk + cumulative exposure logic). Seed oil vs herb: refined/quality-controlled seed oil is generally the preferred form when borage is used medicinally, because the main target compound is GLA; however, product quality and contamination control still matter. Drug interactions (caution): GLA oils have been discussed with anticoagulants (bleeding risk caution is better established for evening primrose oil; borage oil is often grouped in the same “GLA oil” category). Use caution if on anticoagulants/antiplatelets.
Duke (2002) rates borage as a single-plus herb (+) with predominantly folklore-level evidence. Borage seed oil is rich in gamma-linolenic acid (GLA) and has been used for inflammatory conditions such as arthritis and PMS, and for cardiovascular support; typical dose is one 300 mg softgel containing 24% GLA or 2-4 ml liquid leaf extract. Commission E does not approve borage for any indication, and the herb contains hepatotoxic and carcinogenic pyrrolizidine alkaloids, making long-term use inadvisable (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).
External Ids
Botanical Description
Robust, bristly annual herb with hollow, branching stems covered in coarse, stiff hairs. The leaves are large, oval and wrinkled, also coarsely hairy, and smell of cucumber when crushed. The flowers are strikingly bright blue, star-shaped with five pointed petals and a prominent black central cone of anthers, borne in nodding clusters.[1]
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
Grows readily on disturbed, nutrient-rich ground, gardens, waste places and field margins; native to the Mediterranean region and widely naturalised and cultivated across Europe and elsewhere as a culinary and oil-seed crop.[1]
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
Leaves and flowers are picked fresh through the growing season, at their best just as the flowers open; the seed is collected in late summer once the seed heads have dried, pressed for its gamma-linolenic-acid-rich oil.[1]
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
Borage has a long folk reputation, reflected in the old saying 'borage for courage', as a mood-lifting, cooling herb for feverish colds and respiratory complaints, and as a digestive and anti-inflammatory remedy; the fresh leaves and flowers have also been used culinarily. Modern use is centred on the seed oil, rich in gamma-linolenic acid (GLA), for inflammatory and skin conditions.[1]
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
Cold-pressed oil from the berry pulp or seed, applied topically for skin healing or taken orally as a nutritional/antioxidant supplement.
Dosage
A phase-two randomised placebo-controlled trial in moderate persistent asthma used Borago officinalis extract at 5 mL three times daily for one month. Because of pyrrolizidine alkaloid content, whole-herb (leaf/flower) preparations should only be used short-term and from PA-controlled sources; avoid in pregnancy, breastfeeding and liver disease. Educational reference only, not a prescription.
