Bee Propolis is gathered by bees from the leaf buds or bark of trees. So far 17 chemical substances in propolis have been described, some of which are: cinnamic acid, vanillin and an aromatic unsaturated acid characterized by antibacterial effects on certain gram-positive and gram-negative micro organisms.
