It is a single trial. \[1\] - B Limited clinical evidence In 116 postmenopausal women with vaginal dryness, burning or itching, 3 g of sea buckthorn oil a day for 3 months did not significantly improve the vaginal health score compared with placebo; only vaginal tissue integrity improved more. Symptoms eased similarly in both groups. The trial was manufacturer-supported. \[2\] \[1\] ## How is it used? ### Oral oil In studies the oil was taken as capsules with meals: 2 g a day for dry eye and 3 g a day for vaginal dryness, for 3 months. These are study doses, not recommendations. \[1\] \[2\] ## Safety & interactions - There is no safety information for pregnancy or breastfeeding; do not use supplements. - In a small study it reduced platelet clumping; tell your doctor if you take blood thinners or are having surgery. - Very large amounts can cause harmless but noticeable yellow-orange skin colour (carotenodermia). - See a doctor if dry eye or vaginal complaints persist; the oil does not replace treatment. \[1\] \[2\] ### Drug interactions No recorded interactions ### Side effects - Abdominal and digestive complaints - Yellow-orange skin colour at very high intakes (carotenodermia) - Increased joint pain reported in one trial #### ⚕ When to see a doctor - If high fever, shortness of breath or purulent/bloody phlegm develops - If symptoms do not improve within 1–2 weeks or worsen - If severe abdominal pain, jaundice, rash or allergic reaction occurs ## Frequently asked questions Is sea buckthorn oil good for dry eyes? In a study of 100 people, those taking 2 g of oil a day for 3 months reported less eye redness and burning. It is a single trial; see an eye doctor if dry eye persists. Does sea buckthorn oil help vaginal dryness after menopause? In a trial of 116 women, the main outcome (vaginal health score) did not improve significantly versus placebo; only tissue integrity differed. Symptoms eased similarly in both groups. Can I take sea buckthorn while pregnant? Supplements should not be used in pregnancy or breastfeeding because there is no safety information. Does sea buckthorn lower cholesterol? Results are mixed; in a study of 229 people, berry purée did not change cholesterol. The evidence is not enough to recommend it for this. Is sea buckthorn the same as Russian olive? No. Sea buckthorn is Hippophae rhamnoides, while Russian olive (eaten as iğde in Türkiye) is Elaeagnus angustifolia. They belong to the same family but are different plants. ## Sources Source type is not an efficacy rating. A monograph may document traditional use or safety.
