Guarana is a shrub native to South America. Today, it is used in the preparation of many carbonated drinks and has recently been adopted by traditional Chinese medicine for its slimming properties.

Guarana is often found as an ingredient in weight-loss formulas, and for good reason: thanks to its high caffeine content, its seeds help combat excess weight. Thus, Guarana is a natural stimulant that promotes slimming without causing feelings of weakness.
