Key Constituents
Sea buckthorn berries are among the richest natural sources of vitamin C, along with beta-carotene and other carotenoids.
A distinctive fatty-acid profile, particularly rich in palmitoleic acid (omega-7), the basis of the oil's skin- and mucous-membrane-healing reputation.
Antioxidant flavonoids contributing to the plant's anti-inflammatory activity.
The principal bioactive phenolics of the leaf, responsible for most of its antioxidant, anti-inflammatory and antihypertensive activity.
Antioxidant flavonoids of the leaf.
Pentacyclic triterpenes of the leaf cuticle and fruit skin, studied for anti-inflammatory and metabolic effects.
The dominant fatty acid of the fruit oil, a key component of the Mediterranean-diet lipid profile.

Safety, Cautions & Contraindications
Berries and juice are safe as food. Seed oil is safe topically and orally in moderate amounts. May have mild anticoagulant effects. May lower blood pressure and blood sugar — use caution with medications. Allergic reactions are rare.
Duke (2002) rates sea buckthorn as +++ and notes antioxidant, hepatoprotective, antiulcer, and vulnerary activities at the experimental level (score 1). The berries are exceptionally rich in vitamins C (one of the highest natural sources) and E, carotenoids, flavonoids, and omega-7 fatty acids (palmitoleic acid). Duke recommends sea buckthorn as a 'food farmacy' — consumed as part of the regular diet for its nutritional-medicinal benefits. Its radioprotective properties have been studied, though without strong clinical validation. No significant safety concerns at food doses (Duke, 2002).
Olive leaf extract may lower blood pressure; use caution if already on antihypertensive medication. May have mild hypoglycaemic effects. Olive oil is safe for dietary use. Rare olive pollen allergy. Well tolerated in normal culinary and supplement doses.
Duke (2002) includes olive leaf as ++ and notes hypotensive, hypoglycemic, ACE inhibitor-like, and antioxidant activities at the experimental level (score 1). Olive leaf extract (containing oleuropein) has demonstrated blood pressure-lowering and antiarrhythmic effects consistent with clinical support (PHR). Duke notes that traditional Mediterranean use for both the leaf and fruit is food-grade and safe. Olive leaf preparations are used as mild antihypertensives in European phytotherapy. No significant adverse effects are reported at standard herbal doses (Duke, 2002).

Botanical Description
Thorny, deciduous shrub or small tree with narrow, silvery-grey, willow-like leaves. The plant is dioecious (separate male and female plants); female plants bear dense clusters of small, bright orange-yellow berries tightly packed along the branches, giving a striking display in autumn.[4]
Evergreen tree (Oleaceae), typically 3-15 m tall, often gnarled and long-lived, with some specimens surviving for centuries. Leaves are narrow, leathery, lance-shaped, dark green above and silvery-grey beneath. Small, fragrant, creamy-white four-lobed flowers are borne in axillary clusters, followed by a fleshy drupe (the olive) that ripens from green to purple-black.[1]
Habitat
Grows on coastal dunes, riverbanks and disturbed, nutrient-poor or sandy soils; native across temperate Europe and Asia, tolerant of harsh, exposed conditions and cold climates, notably widespread in the Himalayan and Tibetan plateau region.[4]
Native to the Mediterranean basin, the Near East and parts of Africa, and cultivated for millennia across Mediterranean-type climates worldwide (warm, dry summers and mild winters); tolerates poor, rocky, calcareous soils and drought.[1]
Harvesting
Berries are hand-picked (often by cutting whole fruiting branches, given the thorns and fragile fruit) in late summer to autumn once ripe; leaves are picked through the growing season, and seeds are separated from pressed fruit for seed oil.[4]
Leaves can be harvested year-round from pruned or fallen branches, generally at their highest oleuropein content in late autumn and winter; fruit is hand- or machine-harvested from early autumn (green olives) through winter (fully ripe black olives), depending on the intended product.[10]
Traditional Uses
Sea buckthorn has a long Tibetan, Mongolian and traditional Chinese medicine history as a nutritive and healing tonic for respiratory, digestive and skin complaints, and the berries are exceptionally rich in vitamin C and carotenoids; the oil, from both fruit and seed, has a particular traditional and modern reputation for soothing and healing irritated or damaged skin and mucous membranes.[1, 4]
Olive leaf and fruit have a long Mediterranean tradition as a tonic, antipyretic and mild antihypertensive remedy, and olive oil is the foundation fat of the traditional Mediterranean diet, long associated with cardiovascular health. Modern research on oleuropein and other leaf polyphenols supports antioxidant, anti-inflammatory, antimicrobial, blood-pressure-lowering and insulin-sensitising effects consistent with these traditional and dietary uses.[1, 4, 7]

Dosage
Not documented
A meta-analysis of trials for blood pressure used around 500 mg/day of standardised olive leaf extract. Educational reference only, not a prescription; culinary olive oil and leaf tea are considered food-safe at normal dietary amounts.
Drug Class Interactions
Not documented
Pairings
Not documented
Olive leaf and black seed (Nigella sativa) can each mildly lower blood pressure, so taking them together — especially alongside blood-pressure medicines — may add up and lower blood pressure more than expected. Monitor your blood pressure.[11, 18]
