Haselnussblatt

Corylus avellana · Haselblatt

Mechanism

Blätter von Corylus avellana enthalten hohe Gerbstoffgehalte (im Bereich mehrerer Prozent) sowie Flavonoid-Glykoside, vor allem Myricitrin und Quercitrin, dazu Chlorogen-/Kaffeoylchinasäuren und Kaempferol-Rhamnoside (Oliveira et al. 2007, Food Chemistry, ScienceDirect S030881460700413X; ergänzend Sekundärmetabolit-Profile PMID 31665919). Die adstringierende Wirkung wird den Tanninen zugeschrieben, die antioxidative Kapazität den Flavonoiden. Belastbare kontrollierte Pferdestudien zu Verdauung oder Schleimhaut fehlen - die Anwendung ist traditionsbegründet und nicht durch Pferde-RCTs belegt.

Cautions

· Gerbstoffreich - hohe Mengen können Nährstoff-/Eiweißverfügbarkeit senken und adstringierend/stopfend wirken.
· Beim Sammeln verwechslungssicher bestimmen (Abgrenzung zu Eibe, Bergahorn, Robinie, Eiche).

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.
