The Brazilian propolis is considered the best in the world due to the junction of two factors: the genetics of Brazilian bee with the diversity of national flora. Green Propolis, one that contains artepillin-C (a powerful flavonoid), comes from Rosemary (Baccharis dracunculifolia) a typical plant of the Brazilian vegetation. The Brazilian bee has a high capacity for this type of bee activity because it is the result of crossing the African species with the European species.
The Brazilian propolis has a chemical composition quite distinct from other propolis of the rest of the world. This is linked to its botanical origin and species of bee that produce it. The Brazilian propolis originated from the plant called Baccharis dracunculifolia, also known as rosemary-of-field, representing the typical Brazilian specie that can not survive in any other country, is internationally recognized as the best propolis in the world. This is because only the green propolis contains an important phenolic acid called Artepillin-C (3.5-cinnamic acid-4-hydroxycinnamic), chemical compound originally isolated from green propolis, which in Japan is used to treat and prevent tumors.
