Sea buckthorn
CautionSanddorn · (Hippophae rhamnoides)
Oleaster family (Elaeagnaceae)
Description
Dense, thorny shrubs studded with bright orange-red berries line coastal dunes and riverbanks in autumn — sea buckthorn takes its German name (Sanddorn) from this fondness for sandy, exposed ground. The oleaster family delivers, in its ripe autumn fruit, one of the most vitamin-C-rich native berries, backed by carotenoids, tocopherols (vitamin E) and unusually high shares of omega-7, omega-3 and omega-6 fatty acids. Fresh juice and berry tea are traditionally drunk as an immune-supporting winter tonic across Northern and Eastern Europe, while cold-pressed seed and pulp oil are used folk-medicinally on dry, cracked skin and to support wound healing. The berries also find their way into jams, liqueurs and leaf teas throughout the region. Eaten as food, sea buckthorn is considered safe; for medicinal use on stomach complaints or wounds, professional advice is recommended, and pulp oil should be applied with gloves since it stains skin intensely orange.
Fresh berries and pressed juice as an exceptionally vitamin-C-rich food source — traditional immune support in Northern/Central Europe and Central Asia.
Preparation & dosage
RAW / JUICE: Fully ripe orange-red to deep-red berries (Sept–Oct) contain 200–900 mg vitamin C per 100 g depending on variety — among the richest native fruits in vitamin C. Raw, they are intensely sour and astringent; mix with honey, sugar or sweet fruits for direct consumption. More common: pressed juice, undiluted mother juice (10–30 ml daily), or diluted with water and honey as a vitamin-rich cold drink. Do not heat above 60 °C as heat-sensitive vitamins (C, B vitamins) are destroyed. The exceptionally high vitamin C concentration makes sea buckthorn the traditional immune-supporting autumn/winter remedy in Siberia, Central Asia and Northern Europe.
Cold-pressed sea buckthorn seed oil for skin regeneration and wound care — rich in essential fatty acids and vitamin E, folk-medicinally for dry, cracked skin and mucous-membrane irritation.
Preparation & dosage
SEA BUCKTHORN SEED OIL (external): Cold-pressed from seeds, rich in mono- and polyunsaturated fatty acids (linoleic acid ~36 %, oleic acid ~15 %, alpha-linolenic acid ~32 %) and tocopherols (vitamin E). Apply undiluted or incorporated in cream/ointment (2–5 %) to clean skin. Traditionally for wound care, dry, brittle and cracked skin, scar regeneration and mucous-membrane irritation (e.g. minor burns, radiation dermatitis — folk medicine). Distinguish deep-yellow to reddish seed oil from pulp oil (even richer in carotenoids, orange): seed oil has a milder odour and less carotene-colouring effect.
Sea buckthorn pulp oil in salve base for inflamed skin, mucous-membrane inflammation and folk-medicinally for stomach ulcers — high carotenoid profile with regenerative activity.
Preparation & dosage
SEA BUCKTHORN PULP OIL / SALVE: The deep-orange, carotenoid-rich pulp oil (extracted from fruit flesh after de-seeding, C40-carotenoids 30–40 mg/100 g) intensely stains skin orange — apply diluted (3–10 % in neutral base such as shea butter, jojoba oil or beeswax salve). Apply thinly to clean skin, massage briefly. Traditional use for scaly, inflamed skin (dermatitis, psoriasis support), oral and pharyngeal mucous-membrane inflammation, and folk-medicinally for stomach ulcers (oral pulp oil — scientifically insufficiently documented). Stretch-mark prevention in folk medicine of Northern and Eastern Europe.
Folk sea buckthorn berry tea as an immune-supporting winter drink in Northern and Eastern Europe — rich in vitamin C and carotenoids.
Preparation & dosage
SEA BUCKTHORN TEA (berries): 2–4 tsp dried, lightly crushed sea buckthorn berries in 250 ml cold water, bring to boil, simmer 8–10 min (decoction), strain and sweeten with honey to taste. 2 cups daily. Folk use as an immune-supporting winter drink in Russia, the Baltic states and Northern Europe — particularly for cold prevention and influenza-like illness. Vitamin C is heat-sensitive: some is lost during boiling but a significant portion remains (better: cold or warm infusion below 60 °C). For warm infusion, crush berries, pour 70–80 °C water over them, steep 15 min.

Folk sea buckthorn liqueur as a vitamin boost in the cold season — macerated berries in grain spirit or vodka, traditional household recipe of Northern and Eastern Europe.
Preparation & dosage
SEA BUCKTHORN LIQUEUR / MACERATION (folk): 250 g fresh or frozen sea buckthorn berries with 500 ml grain spirit (38 %) or vodka and 3–4 tbsp honey in a sealed jar, macerate cool and dark for 4–6 weeks, shake daily, filter and bottle. 1–2 tablespoons (10–15 ml) 1–2× daily as a traditional vitamin boost during the cold season. Note: This is a folk household recipe (not a standardised tincture) — moderate ethanol content; not for alcohol dependence, pregnancy, lactation or children.

Versatile kitchen ingredient: juice, jam, jelly, sauces, smoothies — highly nutritious, intensely sour; in Mongolian and Tibetan folk medicine also used as a digestive.
Preparation & dosage
KITCHEN: Sea buckthorn berries (fresh, frozen, as mother juice or puree) are used diversely: juice and undiluted mother juice as vitamin-rich drink; cooked into jam, jelly and marmalade (very pectin-rich — gels without added pectin); as fruit sauce with game and cheese; sea buckthorn butter (puree with butter and honey); in smoothies with banana or mango to temper the flavour. In Mongolian and Tibetan folk medicine traditionally as a digestive (berries and leaves) and energy food in high-altitude regions. Intensely sour-astringent — always needs a sweetener (honey, sugar, sweet fruit) in the kitchen.
Folk leaf tea as a mild antioxidant and tonic — used in Russia and Central Asia for joint complaints and general strengthening.
Preparation & dosage
LEAF TEA: 1–2 tsp dried sea buckthorn leaves in 200 ml boiling water, covered, steep 7–8 min, strain. 2 cups daily. Sea buckthorn leaves contain flavonoids (isorhamnetin, quercetin, kaempferol) and tannins. Folk use in Russia and Central Asia as a general tonic and antioxidant, for joint complaints (rheumatism, gout — folk) and skin support from within. Leaf tea is mild in flavour (slightly astringent), not a potent remedy — use leaves harvested in early summer (May–June), before berry ripening. No EMA or Kommission E monograph.

Sea buckthorn is safe in food amounts and nutritionally rich. For sea buckthorn oils (seed and pulp oil) choose quality products from reputable manufacturers — adulteration is known in the market. Pulp oil intensely stains skin and clothing orange — wear gloves during application. For medicinal uses (wound treatment, mucous-membrane inflammation) medical or pharmacist consultation is recommended. For suspected stomach ulcer always seek medical diagnosis — no self-treatment with sea buckthorn oil. With a history of allergies (pollen allergy, cross-reactions in the Elaeagnaceae family) perform a patch test before first use.
Culinary use of berries (juice, jam, smoothies) is considered safe — very high vitamin C content is unproblematic in normal food amounts. Medicinal doses of sea buckthorn oils (seed oil, pulp oil) should be avoided in pregnancy due to lack of safety data. No EMA monograph available.
Culinary use of berries and juice is considered safe during breastfeeding and can contribute to adequate vitamin C intake. Therapeutic oil doses should be avoided as a precaution due to lack of data.
Sea buckthorn juice and berries in household amounts are safe and nutritious for children. Highly concentrated supplements (extracts, capsules) and medicinal oil doses are not recommended for children under 12 due to lack of data. Sea buckthorn liqueur/tincture not for children due to ethanol content.
Drug interactions
Antikoagulanzien (Warfarin, Phenprocoumon, Heparin, direkte orale Antikoagulanzien)
Very high vitamin E content in sea buckthorn oil (seed and pulp oil, up to 160 mg/100 g tocopherols) may inhibit platelet aggregation at medicinal oil doses and potentially enhance anticoagulant effect. Clinically relevant with regular medicinal oil doses; normal food amounts of juice/berries unproblematic. INR monitoring recommended with concurrent therapeutic oil use.
Antidiabetika (Insulin, Metformin, Sulfonylharnstoffe)
Sea buckthorn berries and juice contain fructose and natural sugars; concentrated juices can affect blood glucose. Additionally, antidiabetic properties of the berry (improved insulin sensitivity) are discussed in studies — clinical relevance unclear. Diabetic patients should include sugar-containing sea buckthorn products in dietary planning and monitor blood glucose.
Contraindications
- Hypersensitivity to sea buckthorn or other Elaeagnaceae.
- Sea buckthorn liqueur and ethanol-containing preparations: not for alcohol dependence, liver disease or epilepsy.
Harvested part: ripe berries (autumn)
- Time of day:
- Dry cool morning hours (8–11) in September through October when berries are fully ripe orange-red. Berries remain on the shrub until frost; after the first light frost (October) they become sweeter and easier to harvest as grip on the stem weakens. Important: do not harvest too early — underripe, yellowish berries contain significantly less vitamin C and carotenoids.
- Drying:
- HARVEST: Sea buckthorn berries adhere very firmly to thorny branches — gloves and eye protection essential. Proven methods: (a) cut branches and freeze — after freezing, berries shake or strip off easily; (b) special sea buckthorn rakes (tine combs) for faster hand-picking; (c) for juice: harvest branches directly into container and press immediately. DRYING: 35–45 °C in dehydrator for 12–18 hours to leathery consistency; berry colour deepens to dark orange to brownish. Risk of mould above 15 % residual moisture. STORAGE: Dried berries airtight, dark, cool up to 12 months. Fresh berries: process immediately into juice, oil, jam or freeze (shelf life up to 2 years).
- Time of day:
- Dry mornings (9–12) in May through June — before full berry development, when leaves are freshly unfolded and rich in flavonoids. Collect only at sites/varieties free of pesticide burden. Prefer young shoot leaves (2nd–5th leaf from shoot tip).
- Drying:
- Dry leaves individually or in thin layers on cloth or screens at max. 35 °C in shade, well-ventilated — 2–4 days depending on humidity. Do not dry in sun (loss of chlorophyll and flavonoids). Correctly dried: dry-crackling to the touch, greyish-green colour. Store in dark, airtight jars cool, use within 12 months.
- Ascorbinsäure (Vitamin C)VitaminContent: 0.2-0.9 %Fruit
Lead compound of the sea buckthorn berry: 200–900 mg vitamin C per 100 g fresh weight depending on variety and location — 4- to 15-fold higher than in oranges. Thermolabile (rapidly degraded above 60 °C). Antioxidant, immunomodulating, collagen biosynthesis (wound healing), non-oxidative protection of vitamin E and beta-carotene in tissue.
- Carotinoide (Beta-Carotin, Zeaxanthin, Lycopin, Lutein)OtherContent: 0.03-0.04 %Fruit
C40-carotenoids with beta-carotene as the dominant provitamin A (50–1000 µg/100 g depending on variety); zeaxanthin and lycopene as further representatives. Mainly responsible for the intense orange to red berry colour and the strongly pigmenting effect of pulp oil. Antioxidant, cytoprotective, precursor of vitamin A (important for vision, skin, immune system).
- Tocopherole (alpha-, beta-, gamma-, delta-Tocopherol; Vitamin E)VitaminContent: 0.08-0.16 %Seed
Sea buckthorn seed oil and pulp oil are particularly rich in tocopherols (alpha- and gamma-tocopherol dominant). Alpha-tocopherol (vitamin E) as a fat-soluble antioxidant protects membrane lipids from oxidative damage. Synergistic with vitamin C and carotenoids. Relevant for the skin-regenerating effect of the oil.
- Fettsäuren: Palmitoleinsäure (Omega-7), Alpha-Linolensäure (Omega-3), Linolsäure (Omega-6)OtherContent: 7-14 %Fruit
Sea buckthorn contains the rare omega-7 fatty acid (palmitoleic acid, 16:1 Δ9), mainly in pulp oil (15–35 %), unusual among plant oils. In seed oil, omega-3 (alpha-linolenic acid, ~32 %) and omega-6 (linoleic acid, ~36 %) predominate. This rare fatty acid profile (omega-3/6/7/9 balance) explains the skin-regenerating and mucous-membrane-caring properties of the oil — omega-7 is under investigation in clinical studies for mucous-membrane dryness (vaginal atrophy).
- Flavonoide (Isorhamnetin, Quercetin, Kaempferol, Rutin)FlavonoidContent: 0.1-0.5 %Leaf
Leaves are the most flavonoid-rich plant parts. Isorhamnetin is the characteristic lead flavonoid of the genus Hippophae. Antioxidant, capillary-protective, mildly anti-inflammatory. Detectable in leaf tea preparations. Berries also contain flavonoids (mainly quercetin glycosides), but at lower concentrations than leaves.
- Organische Säuren (Äpfelsäure, Zitronensäure, Quinasäure, Bernsteinsäure)OtherContent: 1.5-3.5 %Fruit
Mainly responsible for the intense sourness of the fresh berry. Malic acid and citric acid dominate. Promote mineral absorption (calcium citrate, iron citrate) and have mild preserving effect. Citric acid stabilises vitamin C (antioxidative synergy).
- Phytosterole (Beta-Sitosterol, Stigmasterol, Campesterol)OtherContent: 0.1-0.8 %Seed
Present at notable concentration in sea buckthorn seed oil. Beta-sitosterol as the main representative — considered cholesterol-lowering with regular intake (phytosterol effect). Support the skin-regenerating effect of the oil by influencing skin barrier function. Sterol-like structure, but no hormonal effect.
- Gerbstoffe / Tannine (Proanthocyanidine, Gallotannine)TanninContent: 0.2-1.0 %Fruit
Partly responsible for the astringent quality of raw berries. Proanthocyanidins (oligomeric procyanidins, OPCs) as a subgroup with antioxidant and capillary-protective activity. Lower tannin content than hawthorn, but still relevant for the astringent organoleptic properties and mild anti-inflammatory effect of berry decoctions.
