Hippophae rhamnoides extract, more commonly known as Sea Buckthorn extract, is a concentrated substance derived from the berries, leaves, and seeds of the shrub. This plant is native to the temperate regions of Europe and Asia, where it has been used for centuries in traditional medicine practices. The extract is created to isolate the beneficial compounds found throughout the plant, resulting in a potent oil or powder.
Key Bioactive Components
Sea Buckthorn extract’s benefits are attributed to its dense concentration of bioactive compounds. It is rich in vitamins, including a high level of Vitamin C and various forms of Vitamin E, such as tocopherols and tocotrienols. The extract also contains carotenoids, which are pigments like beta-carotene and lycopene that the body can convert into Vitamin A. These components are antioxidants.
A defining feature is its comprehensive fatty acid profile, as it is one of the few plant sources to contain all four omega fatty acids:
- Omega-3 (alpha-linolenic acid)
- Omega-6 (linoleic acid)
- Omega-9 (oleic acid)
- Omega-7 (palmitoleic acid)
The inclusion of omega-7, a less common monounsaturated fat, is a notable aspect of its composition. This combination of fatty acids contributes to its wide range of applications.
Topical Use for Skin Health
When applied to the skin, Hippophae rhamnoides extract delivers its components directly to the epidermis. The antioxidants, including vitamins C and E and carotenoids, help protect the skin from damage caused by environmental stressors like UV radiation and pollution. By neutralizing free radicals, these compounds can help maintain the skin’s overall appearance and health.
The fatty acid content is beneficial for skin barrier function. Omega-7, in particular, is a component of the skin’s own lipids, and its presence in the extract helps to hydrate and improve elasticity. This aids in skin regeneration and maintaining a smooth, supple texture, as the combination of fatty acids works to lock in moisture and fortify the skin’s natural defenses.
The extract possesses properties that can soothe the skin. This makes it a useful ingredient in products formulated for sensitive or reactive skin types. Its application may help calm redness and irritation associated with conditions like eczema, rosacea, and acne. These effects are linked to the synergy between its fatty acids and antioxidant compounds.
Dietary Supplementation Benefits
When taken internally, Sea Buckthorn extract offers benefits focused on systemic health. Its compounds are known to support the mucous membranes that line various tracts within the body. This can be helpful for digestive health by soothing the lining of the stomach and intestines, and it extends to other areas, such as providing relief for dry eyes by supporting the ocular mucous membranes.
The cardiovascular system may also benefit from its use. Research suggests that the fatty acids and plant sterols in the extract can help in managing cholesterol levels. By supporting healthy blood lipid profiles, it contributes to overall heart health, and these effects are noted in studies observing individuals with pre-existing high cholesterol.
The high concentration of vitamins supports the body’s immune system. The abundance of Vitamin C is a factor in immune function, and when combined with the other antioxidants present in the extract, it helps bolster the body’s defenses. Regular supplementation can contribute to a more resilient immune response over time.
Choosing and Using the Extract
When selecting a Hippophae rhamnoides product, it is helpful to understand the difference between the two primary forms. Seed oil is higher in omega-3 and omega-6 fatty acids, making it a good choice for general nutritional support. Berry oil, which is sourced from the pulp, is richer in omega-7 and carotenoids, making it more targeted for skin health and mucous membrane support.
For topical use, the oil can be applied directly to the skin, though it is often diluted with a carrier oil like jojoba or coconut oil to improve spreadability. A safety consideration is that the deep orange-red color of the berry oil, due to its high carotenoid content, can easily stain skin and fabrics. For internal use, the extract is available in softgel capsules, with dosages varying based on the concentration and intended purpose.
It is important to be aware of potential interactions. Due to its effect on platelet aggregation, individuals taking blood-thinning medications should consult with a healthcare provider before using Sea Buckthorn extract. This precaution helps ensure that its use does not interfere with existing medical treatments.
