Brunnenkresse

Nasturtium officinale · Watercress

Mechanism

Brunnenkresse (Nasturtium officinale) ist reich an Vitaminen (u.a. C, Carotinoide), Mineralstoffen und dem Glucosinolat Gluconasturtiin, aus dem beim Zerkauen das Isothiocyanat Phenethyl-Isothiocyanat (PEITC) entsteht. In einer randomisierten Humanstudie (85 g/Tag über 8 Wochen) reduzierte Brunnenkresse oxidative Lymphozyten-DNA-Schäden und erhöhte Plasma-Lutein und -Beta-Carotin (Gill et al. 2007, Am J Clin Nutr, PMID 17284750); weitere Humandaten zeigen antioxidative und entzündungsmodulierende Effekte (Nutrients 2021, PMC8391159). Equine Daten fehlen. Praktisch begrenzen der scharfe, schleimhautreizende Geschmack (Senföle) Akzeptanz und Menge; wichtig ist zudem der Standort: Wildbestände an Gewässern können mit dem Großen Leberegel (Fasciola hepatica) oder über die Wasserqualität mikrobiell belastet sein.

Cautions

· Senfölglykoside sind scharf und schleimhautreizend - in größerer Menge Akzeptanz- und Reizproblem.
· Standortrisiko bei Wildbeständen: Großer Leberegel (Fasciola hepatica) und Wasserqualität/Keimbelastung.
· Als Kreuzblütler bei hoher Dauerzufuhr goitrogenes Potenzial (Glucosinolate).

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.
