Key Constituents
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.
Characteristic phenylpropanoid glycosides largely unique to Rhodiola rosea, used as a standardisation marker for commercial extracts.
Phenylethanoid glycosides considered key adaptogenic and antioxidant constituents.
Contribute to the anti-inflammatory and antioxidant activity of the root.

Safety, Cautions & Contraindications
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).
Generally well tolerated. May cause agitation, insomnia, or vivid dreams in sensitive individuals — take in the morning. Avoid in manic episodes or severe anxiety. Theoretical interactions with MAOIs, SSRIs, and CNS stimulants. Avoid during pregnancy and breastfeeding.

Botanical Description
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]
Succulent perennial herb (Crassulaceae), 15-40 cm tall, with a thick, fleshy, branching rhizome that has a rose-like fragrance when cut - the origin of the name 'rosea'. Leaves are fleshy, greyish-green, oval to oblong. Small yellow (occasionally reddish) flowers are clustered in dense terminal heads; the species is dioecious, with separate male and female plants. Fruit follicles turn red as they ripen.[3]
Habitat
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]
Native to arctic and mountainous regions of Europe, Asia and North America (circumpolar), growing in cold, rocky, high-altitude or high-latitude terrain - cliffs, rocky slopes and tundra - tolerating harsh, exposed conditions.[3]
Harvesting
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]
Rhizome and root are dug from plants at least a few years old (traditionally 4-5 years), typically in autumn, then cleaned and dried. Wild populations grow slowly, so cultivated sources are increasingly preferred for sustainability.[3]
Traditional Uses
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]
Rhodiola has a long tradition of use across Scandinavian, Russian and Central Asian folk medicine as a tonic for cold-climate hardiness, physical endurance and mental stamina. It is classified as a modern 'adaptogen', and clinical trials support benefits for stress-related fatigue, mood and cognitive performance.[1, 3]
Preparations
Dosage
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
Pairings
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]
Rhodiola and eleuthero (Siberian ginseng) are classic adaptogens combined in traditional and studied fixed formulas to build resistance to stress and fatigue; used together their stress-protective effects are complementary.[17, 18]
Rhodiola and schisandra are adaptogens co-formulated in clinically studied combinations for stress, fatigue and mental performance; combined use is intended to be synergistic rather than harmful.[17, 18]
