What Is Sea Buckthorn? Benefits, Uses, Nutrition & Scientific Research
What Is Sea Buckthorn? Discover the Nutritional Benefits, Traditional Uses and Scientific Research Behind Sea Buckthorn
Sea buckthorn (Hippophae rhamnoides) is a hardy shrub known for producing clusters of brilliant orange berries packed with naturally occurring nutrients and plant compounds. Despite its name, sea buckthorn is not related to common buckthorn and does not necessarily grow near the sea.
For generations, sea buckthorn berries, seeds, leaves and oils have been incorporated into foods and traditional wellness practices throughout parts of Europe and Asia.
Today, sea buckthorn has attracted considerable scientific and cosmetic interest because its berries and oils contain an unusual combination of carotenoids, flavonoids, vitamin C, vitamin E, phytosterols and fatty acids.
Sea buckthorn is particularly interesting because different parts of the fruit produce oils with distinctly different fatty-acid profiles. Its seed oil is rich in polyunsaturated fatty acids, while its fruit-pulp oil is notable for palmitoleic acid, an omega-7 fatty acid.
What Is Sea Buckthorn?
Sea buckthorn is a deciduous, thorny shrub belonging to the Elaeagnaceae family.
The best-known species is Hippophae rhamnoides, commonly called common sea buckthorn.
The plant produces:
Narrow silvery-green leaves
Thorny branches
Small yellowish flowers
Bright yellow-to-orange berries
Extensive root systems
The berries are particularly distinctive because they grow densely along the branches, sometimes appearing to coat them in bright orange fruit.
Sea buckthorn is extremely hardy and can tolerate environmental conditions that would challenge many other fruit-bearing plants.
Its deep and extensive root system also helps stabilize soil, making the plant valuable for erosion control and land restoration in certain environments.
Where Does Sea Buckthorn Come From?
Sea buckthorn is native across a broad region extending through Europe and Asia.
According to botanical records from the Royal Botanic Gardens, Kew, Hippophae rhamnoides has a native distribution extending across substantial portions of Europe and temperate Asia.
The plant is associated with regions including:
Northern and Central Europe
Eastern Europe
The Caucasus
Central Asia
Russia
Mongolia
China
The Himalayan region
Sea buckthorn can thrive in demanding environments, including:
Sandy soils
Rocky terrain
Mountain slopes
Riverbanks
Coastal areas
Cold climates
Dry environments
Poor soils
Its ability to tolerate difficult growing conditions has contributed to its historical importance in regions where other nutrient-rich fruits can be difficult to cultivate.
Why Is It Called Sea Buckthorn?
The name can be somewhat misleading.
Sea buckthorn is not exclusively a coastal plant.
Some populations grow successfully near coastlines, particularly in sandy environments, but the plant can also be found far inland and at high elevations.
The word buckthorn refers partly to its thorny growth, although sea buckthorn belongs to a different botanical family than plants commonly called buckthorns in the Rhamnus genus.
Its scientific genus name, Hippophae, has an interesting historical origin.
The name comes from Greek words associated with horse and shining.
Historical accounts have linked this name to the traditional practice of feeding sea buckthorn leaves or branches to horses, supposedly contributing to a healthy-looking, glossy coat.
This historical association has contributed to one interpretation of Hippophae as meaning approximately "shining horse."
How Is Sea Buckthorn Used?
Few botanical fruits provide as many usable forms as sea buckthorn.
Sea Buckthorn Berries
The orange berries can be consumed or processed into:
Juices
Purees
Jams
Jellies
Syrups
Sauces
Smoothies
Teas
Functional foods
Dietary supplements
Fresh berries are intensely tart and acidic, so they are frequently processed rather than eaten by themselves.
Sea Buckthorn Juice
Sea buckthorn juice is particularly popular in parts of Europe and Asia.
Its naturally tart flavor may be blended with sweeter fruits or incorporated into functional beverages.
Sea Buckthorn Powder
Freeze-dried or dehydrated berries can be ground into powder and incorporated into smoothies, foods and dietary supplements.
Sea Buckthorn Seed Oil
Oil can be extracted from the seeds.
Sea buckthorn seed oil contains significant amounts of polyunsaturated fatty acids, particularly linoleic acid (omega-6) and alpha-linolenic acid (omega-3).
Sea Buckthorn Pulp Oil
Oil extracted from the fleshy portion of the berry has a different nutritional profile.
Fruit-pulp oil is particularly notable for containing palmitoleic acid, commonly referred to as omega-7.
It also contains carotenoids responsible for its characteristic orange-to-red color.
Herbal and Botanical Supplements
Sea buckthorn may appear in:
Softgels
Capsules
Powders
Liquid extracts
Oil supplements
Multi-botanical formulas
Natural Skin and Hair Care
Sea buckthorn oil has become increasingly popular in natural cosmetic formulations.
It may appear in:
Facial oils
Body oils
Creams

Lip products
Its combination of fatty acids, carotenoids and vitamin E-related compounds has made it particularly interesting to cosmetic formulators.
What Are the Potential Benefits of Sea Buckthorn?
Sea buckthorn contains a diverse mixture of nutrients and phytochemicals, and researchers have investigated the plant in several areas of human wellness.
Evidence varies substantially depending on the preparation being studied.
Provides Naturally Occurring Antioxidants
Sea buckthorn berries contain numerous antioxidant compounds.
These include:
Vitamin C
Carotenoids
Flavonoids
Phenolic compounds
Tocopherols
Other naturally occurring phytochemicals
Antioxidants help protect cells from oxidative stress produced through normal metabolic activity.
The concentration of individual compounds varies according to species, geographic location, ripeness, processing and storage.
Provides Vitamin C
Sea buckthorn berries can contain substantial amounts of vitamin C.
Vitamin C contributes to:
Normal immune function
Collagen formation
Protection of cells from oxidative stress
Normal energy metabolism
Normal functioning of the nervous system
The actual vitamin C content of a finished sea buckthorn product can vary considerably, particularly because processing and storage may reduce vitamin C levels.
Contains Beneficial Fatty Acids
Sea buckthorn oils contain an interesting range of fatty acids.
Depending on whether seed oil or pulp oil is used, these may include:
Alpha-linolenic acid — omega-3
Linoleic acid — omega-6
Oleic acid — omega-9
Palmitoleic acid — omega-7
Palmitic acid
The proportions differ considerably between the seeds and fruit pulp.
Provides Omega-7 Palmitoleic Acid
One of sea buckthorn's most distinctive nutritional characteristics is its concentration of palmitoleic acid, commonly marketed as omega-7.
Sea buckthorn fruit-pulp oil is one of the better-known botanical sources of this fatty acid.
Omega-7 has attracted scientific interest in areas including lipid metabolism, skin wellness and mucous-membrane health.
However, research remains developing, and omega-7 should not be presented as a treatment for medical conditions.
May Support Skin Wellness
Sea buckthorn oil's fatty-acid and antioxidant composition has made skin health one of its most popular applications.
Fatty acids are important structural components of the skin's natural lipid barrier.
Sea buckthorn oils also contain compounds such as:
Carotenoids
Tocopherols
Phytosterols
Fatty acids
These characteristics help explain why sea buckthorn has become popular in cosmetic products formulated to support soft, moisturized and healthy-looking skin.
May Support Cardiovascular Wellness
Researchers have investigated sea buckthorn berries and oils in relation to cardiovascular measurements such as:
Blood lipids
Cholesterol
Platelet activity
Oxidative stress
Blood pressure
Some clinical studies and systematic reviews have reported potentially favorable changes in certain cardiovascular measurements, while other findings have been inconsistent.
Sea buckthorn should not be used as a substitute for prescribed cardiovascular medications or professional medical care.
Why Is Sea Buckthorn Oil So Popular for Skin Care?
Sea buckthorn oil has become one of the more recognizable botanical oils in modern natural skin care.
Its appeal comes from its unusual combination of fatty acids and antioxidant pigments.
Fatty acids contribute to the skin's natural lipid barrier, which plays an important role in retaining moisture.
Sea buckthorn oil may therefore be incorporated into formulations designed to:
Condition dry-feeling skin
Support the skin's moisture barrier
Improve the feel of rough skin
Provide botanical antioxidants
Maintain soft, supple skin
Support healthy-looking skin
Its bright orange color comes largely from naturally occurring carotenoid pigments.
Because concentrated sea buckthorn pulp oil can be intensely colored, cosmetic formulators often use controlled amounts or combine it with other botanical oils.
Sea Buckthorn for Hair and Scalp Care
Sea buckthorn oil is also incorporated into hair and scalp products.
Its fatty-acid composition makes it useful as an emollient ingredient capable of conditioning the hair and skin.
It may be included in products designed to support:
Soft-feeling hair
Hair conditioning
Dry scalp care
Moisture retention
Healthy-looking hair
Sea buckthorn should not be represented as clinically proven to regrow hair or treat scalp diseases without appropriate evidence.
Its most supportable cosmetic role is as a nutrient-rich conditioning botanical oil.
What Plant Compounds Are Found in Sea Buckthorn?
Sea buckthorn is chemically complex.
Researchers have identified numerous naturally occurring constituents, including:
Flavonoids
Phenolic acids
Carotenoids
Tocopherols
Tocotrienols
Phytosterols
Organic acids
Fatty acids
Vitamin C
Polysaccharides
Other bioactive plant compounds
Common carotenoids may include:
Beta-carotene
Lycopene
Zeaxanthin
Other xanthophylls and carotenes
Flavonoids identified in sea buckthorn include compounds derived from:
Quercetin
Isorhamnetin
Kaempferol
The exact composition varies significantly among different sea buckthorn varieties and preparations.
Sea Buckthorn Seed Oil vs. Sea Buckthorn Berry Oil
This is an important distinction when shopping for sea buckthorn products.
Sea Buckthorn Seed Oil
Extracted primarily from the seeds.
It typically contains substantial amounts of:
Linoleic acid — omega-6
Alpha-linolenic acid — omega-3
Oleic acid — omega-9
It is generally lighter in color than pulp oil.
Sea Buckthorn Pulp Oil
Extracted from the fleshy portion surrounding the seed.
It generally contains more:
Palmitoleic acid — omega-7
Palmitic acid
Carotenoids
It usually has a much deeper orange-to-red color.
Whole-Berry Oil
Some products use oils produced from larger portions of the fruit rather than exclusively the seed or pulp.
These can have yet another fatty-acid and phytochemical profile.
Therefore, the terms sea buckthorn oil, seed oil and pulp oil should not automatically be treated as interchangeable.
Scientific Research on Sea Buckthorn
Sea buckthorn has become the subject of extensive laboratory research and a growing amount of human clinical investigation.
However, evidence differs substantially among areas of use.
Research on Cardiovascular and Metabolic Health
Researchers have conducted randomized controlled trials evaluating sea buckthorn products and cardiovascular risk factors.
Systematic reviews and meta-analyses have examined measurements including cholesterol, triglycerides, blood glucose and blood pressure.
Some analyses suggest potentially favorable effects on certain measurements, particularly among specific populations.
However, results are not uniform across studies.
Differences in sea buckthorn preparations, study duration, participant health and dosage make direct comparisons difficult.
Research on Skin Wellness
Sea buckthorn seed and pulp oils have been studied in relation to skin characteristics.
Human research has investigated oral sea buckthorn oil and measurements related to skin hydration, elasticity and barrier function.
Sea buckthorn's fatty acids and carotenoids have also generated substantial interest in topical cosmetic research.
These findings support continued investigation but should not be interpreted as evidence that sea buckthorn treats dermatological diseases.
Research on Dryness and Mucosal Wellness
One particularly interesting area of clinical research involves mucous-membrane dryness.
Sea buckthorn oil has been investigated in randomized clinical studies involving individuals experiencing certain forms of dryness.
Researchers have proposed that the fatty acids in sea buckthorn oil may contribute to maintaining epithelial and mucosal tissues.
Results from individual studies are promising enough to justify further research, but sea buckthorn should not be considered a replacement for medical evaluation or treatment of persistent dryness.
Antioxidant Research
Sea buckthorn berries contain abundant antioxidant phytochemicals, making oxidative stress another major research area.
Laboratory studies have demonstrated antioxidant activity associated with sea buckthorn extracts, flavonoids and carotenoids.
Human studies have also evaluated biomarkers associated with antioxidant status.
Laboratory antioxidant activity alone, however, does not demonstrate that a botanical prevents or treats disease in humans.
Sea Buckthorn and Traditional Asian Herbal Practices
Sea buckthorn has a particularly rich history across parts of Asia.
The berries and other portions of the plant have appeared in traditional wellness systems in regions including:
Tibet
Mongolia
China
Russia
Central Asia
Traditional applications have varied substantially among cultures and preparations.
Modern scientific research sometimes investigates these historical applications, but traditional use and scientifically established clinical effectiveness should always be distinguished.
A plant can have meaningful historical importance without every traditional claim being proven by modern medicine.
Sea Buckthorn and Natural Skin Care
Sea buckthorn provides an excellent example of the overlap between nutritional botanicals and natural personal care.
Its berries are consumed as foods and supplements, while its oils are incorporated into topical preparations.
This versatility comes from its diverse nutritional composition.
In cosmetic products, sea buckthorn can contribute:
Emollient fatty acids
Botanical antioxidants
Carotenoid pigments
Vitamin E-related compounds
Phytosterols
These properties make it particularly suitable for formulas intended to maintain moisturized, conditioned and healthy-looking skin.
Is Sea Buckthorn Safe?
Sea buckthorn berries have a history of use as food, and sea buckthorn products are generally well tolerated by many people when used appropriately.
However, concentrated supplements and extracts require additional consideration.
Possible gastrointestinal effects may occur in some individuals.
Consult an appropriate healthcare professional before using concentrated sea buckthorn supplements if you:
Are pregnant or breastfeeding
Take prescription medications
Use anticoagulant or antiplatelet medications
Take medications for blood pressure
Take medications affecting blood glucose
Have a bleeding disorder
Are preparing for surgery
Have an existing medical condition
Research regarding significant drug interactions remains limited, so appropriate caution is advisable when combining concentrated botanical supplements with prescription medications.
Topical sea buckthorn products should be discontinued if irritation or sensitivity occurs.
Choosing High-Quality Sea Buckthorn
Because different portions of the fruit produce substantially different oils, product labeling is particularly important.
Look for products that clearly identify whether they contain:
Sea buckthorn berry
Sea buckthorn powder
Sea buckthorn seed oil
Sea buckthorn pulp oil
Sea buckthorn fruit oil
Sea buckthorn extract
Reputable manufacturers should also use appropriate sourcing, processing and contaminant-testing practices.
For oils, extraction and storage methods matter because unsaturated fatty acids can be susceptible to oxidation.
Protection from excessive heat, oxygen and light can help maintain product quality.
Sea Buckthorn as Part of an Herbal Wellness Lifestyle
Sea buckthorn demonstrates how one plant can bridge the worlds of traditional herbalism, modern nutrition and natural personal care.
Its vibrant berries provide numerous naturally occurring phytochemicals, while its seeds and fruit pulp produce oils with distinctly different fatty-acid profiles.

Final Thoughts on Sea Buckthorn
Sea buckthorn (Hippophae rhamnoides) is a remarkable fruit-bearing shrub with a history extending from traditional Asian wellness practices to modern nutrition and cosmetic science.
Its bright orange berries contain vitamin C, carotenoids, flavonoids and other naturally occurring antioxidant compounds, while its seeds and fruit pulp produce nutrient-rich oils.
One of the plant's most interesting characteristics is the difference between these oils. Sea buckthorn seed oil is particularly rich in omega-3 and omega-6 fatty acids, while the fruit-pulp oil is an unusually rich botanical source of palmitoleic acid, commonly known as omega-7.
Modern research has investigated sea buckthorn in relation to cardiovascular measurements, skin wellness, mucosal health, oxidative stress and metabolism. Although some findings are promising, clinical evidence varies according to the preparation and intended use, and additional high-quality human research is necessary.
Sea buckthorn is therefore best understood not as a miracle treatment, but as an unusually nutrient-dense botanical whose berries, seeds and oils provide a fascinating combination of traditional use, nutritional value and emerging scientific research.
