The ground powder of the guarana plant can have a caffeine content of up to 8%. This is about 4 times as much as in the coffee bean, but guarana should not only be used because of its stimulant effect.

Guarana has also proven itself as an anti-hangover. It cleanses the digestive tract and supports the intestines in detoxification. Due to the tannins and saponins it contains, which contract the gastrointestinal area and kill bacteria, guarana is also very popular against flatulence or as an anti-diarrheal agent.
