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.
Thought to contribute to the antidiabetic and cholesterol-lowering effects.
Mucilaginous soluble fiber that slows carbohydrate absorption, a key mechanism behind the blood-sugar-lowering effect.
An unusual amino acid studied for insulin-potentiating activity.
Aromatic lactone responsible for fenugreek's characteristic maple-syrup smell, including the body-odor effect reported with supplementation.

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).
Fenugreek appears https://www.nccih.nih.gov/health/fenugreek for most people.
Less serious side effects like diarrhea and indigestion have been reported anecdotally. You may also experience https://pubmed.ncbi.nlm.nih.gov/26251835/, which could be harmful if you have an eating disorder or are trying to https://www.healthline.com/nutrition/how-to-gain-weight. Moreover, some people report a strange and slightly sweet body odor when supplementing, but this is unconfirmed. Given its effect on blood sugar, fenugreek should be used with caution if you’re taking diabetes medication or other supplements that lower blood sugar levels.
Duke (2002) provides strong clinical evidence (score 2) for fenugreek's hypoglycemic and hypocholesterolemic activities — among the best-evidenced herbal treatments for blood sugar and lipid management. Anti-inflammatory and demulcent activities also have clinical support. The seed is Commission E approved as an appetite stimulant. Dose: 6–50 g of ground seeds daily for blood sugar management; 1–4 g seeds in tea for digestive use. The plant has lactagogue effects and can cause maple syrup-like body odor due to sotolon content. Contraindicated in pregnancy at medicinal doses due to uterotonic effects (Duke, 2002).

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]
Erect annual herb with trifoliate leaves, each leaflet oblong and finely toothed toward the tip. Small, pale yellow to white, pea-like flowers are borne singly or in pairs in the leaf axils, followed by long, slender, curved seed pods.[11]
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]
Cultivated widely as a food and forage crop; native to the eastern Mediterranean and western Asia, now grown throughout South Asia, the Middle East and North Africa.[11]
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]
Leaves and young sprouts are harvested throughout the growing season; seed pods are collected when fully mature and dried, then the hard seeds are threshed out.[11]
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]
Fenugreek seed has an ancient tradition across the Mediterranean, Middle East and South Asia as a digestive and appetite-stimulant remedy and lactation aid, and modern clinical research strongly supports its traditional use for blood sugar and cholesterol management, formalised in Commission E approval as an appetite stimulant.[5, 11, 12]
Preparations
Ground seeds taken with food, or whole seeds soaked/simmered as a tea, the traditional preparation for digestive and blood sugar support.
Standardized seed extract in capsule form, the form most used in clinical trials on blood sugar and cholesterol.
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.

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]
Fenugreek and bitter melon can each lower blood sugar, so taking them together — especially alongside diabetes medicines — may add up and increase the risk of hypoglycaemia. Monitor your blood glucose.[15, 16]
