In vitro experiments with blackcurrant leaf extracts or isolated constituents demonstrated anti-inflammatory and anti-oxidant effects.
In vivo experiments with blackcurrant leaf extracts or isolated constituents in animals demonstrated anti-inflammatory properties in different models (carrageenan-induced rat paw oedema, cotton pellet-induced granuloma, Freund’s adjuvant-induced arthritis tests), as well as analgesic, diuretic and anti-hypertensive properties.
Preclinical safety data were assessed in toxicity studies.
