As we start to see a return to our roots, foods long gone from our modern diets are being rediscovered and making a remarkable comeback thanks to an increased interest in health-conscious eating. Sea-buckthorn berries are one such lost food made popular once again due to their incredible therapeutic potential. The bright colored orange berries are a rich source of carotenoid antioxidants, but also vitamin C and flavonol antioxidants. Both the fruit pulp and seeds are high in vitamin E and a source of vitamin K, potassium, manganese, molybdenum, copper, chromium, iron, selenium and zinc. Sea-buckthorn berry and seed oils are rich in unsaturated fatty acids, vitamin E and carotenoid antioxidants, hence their orange to yellow color. Uses of sea-buckthorn berries and preparations range from cosmetic to therapeutic, with emphasis on their regenerative, anti-inflammatory and immuno-stimulating properties and their antioxidant action.
What is sea buckthorn?
Sea-buckthorn is a genus of thorny, extensively ramified, hardy shrubs with edible, bright orange fruits with good nutritional value and therapeutic properties. Sea-buckthorns are present throughout the Northern hemisphere, from Canada to all of Europe to Russia, Mongolia and China. They can be found growing naturally in a variety of habitats ranging from mountain slopes down to the sea coast, with large populations thriving in sunny river banks, but also salty, sandy and semi-arid areas. The presence of sea-buckthorn in some rather inhospitable areas such as the sea coast or semi-desert areas has led to popular alternative names such as seaberry and sandthorn. Species include Hippophae rhamnoides, also known as the common sea-buckthorn, Hippophae goniocarpa, H tibetana, H. gyantsensis, H. salicifolia and H. neurocarpa, and subspecies.
What is sea buckthorn used for?
- Berries medicinal uses: fruit and seed oil (sea-buckthorn berry oil, seed oil), fruit juice, tea and syrup, macerates, tinctures, extracts and nutritional supplements are used for nutritional supplementation, reducing excess stomach acid (in GERD), dry eyes and skin (xerosis), arthritis pain management, skin ulcers, canker sores, acne, even for radiation damage therapy and more.
- Berries cosmetic uses: sea-buckthorn berry and seed oil are common active ingredients in eye creams, face creams, reparative, regenerative or anti-aging face, neck and hand creams, body lotions, face toners, shampoos, reparative conditioners etc.
- Berries culinary uses (skin and pulp): tart and sweetened sauces, jam, jelly, puree, tea, juice, syrup, pie and pastry fillings, or non-toxic dye for at-home use.
- Berry seeds uses: production of oil for cosmetic and therapeutic use (arthritis, rheumatism, dry skin, wrinkles, acne, mouth sores or canker sores, skin ulcerations etc.). The seed cake left over from oil production can be used as animal fodder.
- Whole plant: soil stabilization, combating soil erosion, restoring vegetation density, improving soil quality through nitrogen fixation and moisture retention, landscaping and various ornamental uses (e.g. flower arrangements), crop sheltering (e.g. protection from strong winds), use as animal food etc.
What do sea buckthorn berries look like?
Sea-buckthorn berries are the fruits of the plant with the same name. Despite the name, they are not true berries, but rather drupes like sweet and sour cherries, peaches, nectarines and olives. Most species of the plant produce small, bright orange-colored berry-like fruits, sometimes also pale yellow. The fruits are roundish or egg-shaped and have a thin peel with a meaty, somewhat juicy, pulp and one hard seed each. At the end opposite to the stem, there are remnants of sepals visible on each fruit. Sea-buckthorn berries grow in such a closely-knit richness they severely weight down branches. The plant is a shrub or tree-sized plant growing anywhere from 1 to 6 meters in height, and is extensively ramified and typically thorny. Sea-buckthorn is a hardy species, tolerating and thriving in alpine and sub-alpine regions down to salty, sandy sea coast areas and dry semi-desert conditions.
What does sea buckthorn taste like?
Sea-buckthorn does not taste like the type of fruit we are used to eating nowadays. This is probably the main reason for its lack of popularity among the general population. Sea-buckthorn berries taste tart and astringent as a result of the organic acids such as malic acid, ascorbic acid, quinic acid and other acids in the fruit pulp, but also oily due to the high content of oil in both the seeds and pulp. To improve their taste, sea-buckthorn berries are best left on the plant until the first frosts – freezing temperatures blet the fruit, that is, soften and somewhat decay them, achieving a reduced astringency that makes the berries taste more palatable. They are otherwise not flavorful. The fruits are as hardy as the plant itself and can stay on the branch all winter.
