Key Constituents
Principal immunomodulatory constituents, the main focus of anticancer-adjunct and immune research.
Bitter triterpenes associated with anti-inflammatory, hepatoprotective and adaptogenic 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
Generally well tolerated at standard doses. May cause mild digestive upset, dry mouth, or dizziness in some individuals. May enhance the effects of anticoagulant and antihypertensive medications. Avoid during pregnancy and breastfeeding. Extended use beyond 6 months is not well studied in humans.
Duke (2002) rates reishi (Ganoderma lucidum) as + and notes immunostimulant, hepatoprotective, antioxidant, antitumor, and hypoglycemic activities at the experimental level (score 1). It is a key adaptogen in traditional Chinese medicine, valued for its polysaccharide (beta-glucan) content. Duke notes antiviral (score 1) and anti-aggregant activities. No strong clinical trials existed at time of publication, but lentinan and polysaccharide fractions from related species show immunomodulatory potential. Duke suggests caution in bleeding disorders due to anti-aggregant activity (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
Bracket (shelf) fungus (not a true plant) that grows on the trunks and stumps of deciduous trees. It develops a hard, kidney- or fan-shaped cap with a glossy, varnished, red-brown to mahogany crust and concentric growth rings, often on a lateral woody stalk; the pale underside is covered in fine pores that release rusty-brown spores. The mycelium spreads through the wood substrate before fruiting.[1]
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 as a wood-decay fungus on the stumps and trunks of deciduous trees (notably maple and other hardwoods) in East Asian forests; also widely cultivated commercially on hardwood logs or sawdust substrate.
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
Wild fruiting bodies are collected once mature; cultivated material is harvested from logs or substrate at maturity, then dried and processed into slices, powder or extract.
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
Reishi/lingzhi, the 'mushroom of immortality', is one of the most revered tonic fungi in traditional Chinese medicine, used for centuries to support vitality, calm the spirit, strengthen immunity and promote longevity; this traditional tonic reputation is now studied for immunomodulatory, anticancer-adjunct and metabolic effects.[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.
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]
