A major breakthrough in the quest for an all-natural product has been announced. Known as propolis, this beehive product was known to ancients but not until recently has it been used by modern scientists in nutritional professions. It is gathered by the 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.

Propolis capsule shells are of vegetable origin.
