Olivenblatt

Olea europaea L. · Oleae folium · Olive leaf · Olivenbaumblatt

Mechanism

Olivenblatt ist reich an dem Sekoiridoid Oleuropein (bis ~17% im Extrakt) sowie Hydroxytyrosol und Flavonoiden (Luteolin-/Apigenin-Glykoside). Diese Polyphenole sind starke Radikalfaenger, steigern in experimentellen Modellen antioxidative Enzyme (Katalase, SOD, Glutathionperoxidase) und wurden mit endothelialer/vasodilatatorischer Wirkung in Verbindung gebracht (tierexperimentell: renale/karotide Haemodynamik, oleuropein-vermittelt, PMC5780626). Randomisierte, kontrollierte Humanstudien zeigten mit standardisiertem Olivenblatt-Extrakt (z. B. 136 mg Oleuropein/Tag) signifikant niedrigeren Blutdruck bei Praehypertonikern (Lockyer et al. 2016, PMID 26951205). Kontrollierte equine Studien fehlen; Olivenblatt wird in Pferde-Kraeuterblends als natuerliches Antioxidans/Kreislauf-Support gefuehrt (Extrapolation, kein equiner Wirknachweis). Einordnung: Ergaenzungsfuttermittel, antioxidativ/stoffwechselunterstuetzend diskutiert - keine Heilaussage.

Cautions

· kann blutdruck- und blutzuckersenkende Wirkung verstaerken - Vorsicht bei entsprechender Medikation/Begleiterkrankung
· keine Sicherheitsdaten fuer tragende/laktierende Stuten in equiner Dosis
· Polyphenol-/Oleuropein-Gehalt schwankt stark je Charge und Extraktqualitaet
· kein spezifischer FEI-Verbotsstoff; Wettkampfkarenz beachten

How the Equiterna Score is built

The Equiterna Score combines three dimensions into a value of 0-100: science (40%), practical experience (30%) and safety (30%). It is transparently derived from evidence level, attributed sources (PubMed/journals), legal classification and cautions. The FEI doping status is shown separately as a competition-law note and does not enter the score. Commissions and vendor relationships have no influence on the score. In addition, the editorial safety rating caps the result: it limits the safety dimension and the overall tier (orange: at most solid). For entries rated red, no score is calculated at all. The rating never raises anything — a green rating does not lift a calculated value.

An editorial assessment of the evidence and safety situation — not a healing claim and not an individual recommendation. It does not replace veterinary advice.
