Research & Evidence
Vicenin refers to C-glycosylated flavones derived from apigenin, most commonly vicenin-2, which carries sugar groups attached directly to the flavone core. It occurs in holy basil (tulsi) and a range of other plants and is one of the water-soluble flavonoid constituents of such herbs. Like many dietary flavonoids it has been studied in preclinical settings for antioxidant-type activity, but little is firmly established about its effects in humans.
Toxicity & Safety
As a flavonoid found in edible and medicinal plants, vicenin is generally presumed to have low toxicity at dietary levels; specific safety data are limited.
