Means of plant origin. It has astringent, anti-inflammatory, hypoglycemic, antiseptic, hemostatic and bactericidal action.
Contains fruit acids (including quinine, malic and citric acids), tannins (mainly catechins, including oligomeric procyanidins), anthocyanoids (main components - delfinidine-3-O-arabinoside, delfinidine-3-O-galactoside, delphinidin-3-O glucoside, cyanidin, petunidin, peonidine, malvidin), flavonoids (including hyperoside, isoquercitin, quercitrin, astragaline), iridoids (including asperuloside, onropine), caffeic acid and its derivatives (including chlorogenic acid), pectins.
Anthocyanosides promote the regeneration of the photosensitive pigment of the retina - rhodopsin and thus improve the sensitivity of the retina to various levels of light radiation and enhance visual acuity in low light.
