Sea Buckthorn Oil: Benefits for Mucous Membranes
Sea buckthorn is an extraordinary plant. Its bright orange oil is exceptionally rich in vitamin A, which is essential for sharp vision and healthy skin. It also has remarkable restorative effects on mucous membranes, which can be damaged by dryness, mechanical irritation, or chemical exposure. Dry mucous membranes not only cause noticeable discomfort but can also pose a health risk. Moist, elastic mucous membranes act as a reliable barrier against external infections caused by bacteria and fungi.
Sea buckthorn oil is rich in unsaturated fatty acids, fat-soluble vitamins, sterols, and natural antioxidants such as polyphenols. For restoring mucous membranes, one component of particular value is the omega-7 fatty acid palmitoleic acid. This compound is naturally present in human sebum and mucous membranes, where it supports cellular tissue and accelerates wound healing. In some sea buckthorn varieties, palmitoleic acid makes up as much as 43% of the oil—an exceptionally high concentration.
The oil is also abundant in carotenoids such as zeaxanthin, beta-carotene, and lutein. These compounds are valued as powerful antioxidants; beta-carotene additionally serves as a biological precursor of vitamin A.
Sea buckthorn oil is a rare product in that it can be applied directly to mucous membranes (it is completely non-irritating) and can also be taken orally in capsule form. In both cases, its positive effects are noticeable.
Dry Eye Syndrome
Dry eye syndrome, also known as dry conjunctivitis, occurs when the normal production of tear fluid is disrupted. In healthy eyes, a protective tear film forms with every blink, keeping the eyes moist. With dry eye syndrome, this process is impaired, leading to irritation of the mucous membrane, redness, and a burning sensation. Causes range from prolonged computer use and air pollution to underlying conditions such as diabetes or autoimmune diseases.
According to numerous studies—including a large-scale clinical trial conducted at the University of Turku (Finland) in 2011—oral intake of sea buckthorn oil has a positive effect on tear film osmolarity and symptoms of dry eye, even in people who wear contact lenses.
Oral Cavity Problems
Stomatitis is characterized by inflammation, ulcers, and wounds on the oral mucosa. These usually arise from minor injuries (such as brushing too hard or small burns) in combination with reduced immunity. Research by a Finnish team demonstrated that applying sea buckthorn oil directly to areas affected by stomatitis in children led to healing in an average of just two days. A 2016 study by Indian researchers also confirmed the beneficial effects of sea buckthorn oil in chronic periodontitis.
Gastrointestinal Health
Sea buckthorn oil may help soothe and protect the lining of the stomach and intestines, making it potentially useful in conditions such as gastritis and ulcers.
Urogenital Health
Encapsulated sea buckthorn oil can help relieve dryness and discomfort in the urogenital area, particularly for women experiencing vaginal dryness during menopause. Similar symptoms may occur in women with estrogen deficiency due to low body weight or surgery on reproductive organs. Conditions such as diabetes and hypertension can also reduce hydration of the urogenital mucosa. In these cases, taking sea buckthorn oil may help alleviate discomfort.
In one study of postmenopausal women not receiving hormone therapy, participants took 3 g of sea buckthorn oil in capsules daily for three months. Results showed a clear improvement in the condition of the vaginal mucos
Production and Quality
The production of sea buckthorn oil is similar to that of olive oil. As with olive oil, the market offers products of varying quality—including adulterated, diluted, or improperly processed oils. The highest-quality sea buckthorn oil is made from berries harvested from organically grown plants under strict quality control. Such oil is guaranteed to be free of pesticides, heavy metals, and other harmful substances.
