Burns ✪✪✪✪✪
In a randomized, triple-blind clinical study, the effectiveness of sea buckthorn cream for treating second-degree burns was compared with that of dressings containing 1% silver sulfadiazine (SSD). The study included 55 patients with second-degree burns, randomly divided into two groups: one treated with sea buckthorn cream and the other with SSD cream. The dressings were changed until the wounds had completely healed, monitored using the Bates-Jensen Wound Assessment Tool. The results showed that the healing time for second-degree burns was significantly shorter for the group treated with sea buckthorn cream, with an average of 6.7 days, compared with the group treated with SSD, where healing took an average of 11.2 days. This statistically significant difference demonstrates the superior clinical effectiveness of sea buckthorn cream in treating second-degree burns.

Common cold ✪✪✪✪✪
Sea buckthorn is renowned for its high vitamin C content, with about 400 mg per 100 grams of fruit, making it an important source of antioxidants. Traditionally, it is used to strengthen the immune system and fight infections such as the common cold. However, clinical research conducted on healthy volunteers did not demonstrate clear effectiveness of sea buckthorn in preventing or reducing the duration of common cold symptoms. In this study, daily consumption of 28 g of frozen sea buckthorn berry purée for 90 days showed no significant difference compared with a placebo in reducing the risk of developing a cold or the duration of symptoms.

Dermatoses ✪✪✪✪✪
Initial clinical research reveals mixed results regarding the use of sea buckthorn seed and pulp oil to treat dermatoses. One study suggests that daily consumption of 5 g of sea buckthorn seed and pulp oil for four months may improve the severity of atopic dermatitis, although the effectiveness of seed oil alone has not been confirmed, and that of sea buckthorn pulp is not significantly different from placebo. In addition, topical application of 10% or 20% sea buckthorn cream for four weeks did not reduce the severity of atopic dermatitis in mild to moderate cases. However, a small clinical study showed that applying a sea buckthorn fruit extract in corn oil twice daily for eight weeks reduces the severity of psoriatic lesions compared with corn oil alone.

Wrinkles ✪✪✪✪✪
Preliminary clinical research on individuals with photo-induced facial damage and severe fine wrinkles examined the effects of a specific combination product (GliSODin Skin Nutrients Advanced Anti-Aging Formula, Isocell North America Inc.). Taken as a capsule three times daily for 90 days, in addition to the application of 0.1% tazarotene cream, this treatment improved the appearance of wrinkles, hyperpigmentation, and sun damage compared with the use of tazarotene cream alone. Each three-capsule dose contains 200 mg of sea buckthorn berry oil, 600 mg of krill oil, 10 mg of zinc, 400 IU of vitamin D, 100 mg of cocoa bean extract, 30 mg of hyaluronic acid, 30 mg of red clover flower isoflavones, and 500 mg of melon extract (SOD).

Healthy aging ✪✪✪✪✪
The study published in Clinical Interventions in Aging in 2019 examined the effects of a polyphenol-rich extract from sea buckthorn berries on stem cell mobilization in healthy human subjects. The randomized, double-blind trial involved taking 500 mg of the extract and measured the increase in specific types of stem cells in the blood. The results showed rapid and selective mobilization of several types of stem cells, including endothelial and mesenchymal stem cells, which could contribute to tissue regeneration and repair. These observations could explain the traditional use of sea buckthorn for preventive health and slowing the aging process, highlighting its potential in possible applications in regenerative medicine.

Properties
Antioxidant
Numerous laboratory, animal, and human studies have demonstrated the antioxidant activity of sea buckthorn. This property could explain its potential beneficial effect on various diseases, including cancer, cardiovascular disease, diabetes, immune disorders, inflammatory diseases, liver disorders, radiation-induced injuries, eye disorders, and chemotherapy-related toxicity. Sea buckthorn flavonoids, in particular, are recognized for their ability to neutralize free radicals and protect against oxidative stress and radiation.
Usages associés
Anti-aging
Traditionally used to slow the aging process and promote regeneration, sea buckthorn, thanks to an extract rich in proanthocyanidins, mobilizes stem cells involved in regeneration, including certain types of stem cells.
Usages associés
Cardiovascular
Sea buckthorn flavonoids are known to lower cholesterol, reduce inflammation, and decrease platelet aggregation, thereby contributing to a reduced risk of cardiovascular disease. In healthy volunteers, consumption of sea buckthorn berry purée significantly reduced CRP, an indicator of inflammation.
Anti-inflammatory
In healthy subjects and obese patients, sea buckthorn berries and oil have demonstrated their ability to reduce C-reactive protein concentrations.
Dermatological effect
Sea buckthorn promotes wound healing. Animal studies and some human data suggest that its extracts protect cells against lipid peroxidation injuries and improve epithelial tissue regeneration and wound granulation, thereby increasing blood flow to injured areas.
