How and What to Use Guarana
Guarana (Paullinia cupana, Sapindaceae) is an evergreen climbing plant in the Amazon rainforests of South America. It grows mainly in the territories of Brazil. The plant is distinguished by its huge leaves and beautiful flower bouquets.
The great international interest in it is due to its small red fruits, which are about the size of a coffee bean. Every fruit contains within itself a seed that surprisingly resembles an eye before you peel it off completely.
After that, it resembles a hazelnut. Every seed contains five times the concentration of caffeine found in coffee beans of the same size. The history of the plant is unwritten and it lost in the cultural myths of the Tupi and Guarani tribes, inhabiting the Amazon jungle. Legend says that one of the local deities killed a child, truly loved by his tribe.
Another deity planted the eyes of the dead child - the left one in the village and the other one in the jungle. That is how the wild and cultivated forms of Guarana appeared.
