Guarana

Paullinia cupana

The seeds contain about twice as much caffeine as coffee beans. Guarana is used in energy drinks and soft drinks; its stimulating effect comes from caffeine.

Safety notes

Too much caffeine causes palpitations, insomnia and restlessness; watch combinations with coffee, energy drinks and supplements. Avoid with heart rhythm disorders, in pregnancy or for children.

Cautions by tradition (2)
  • Herbal medicine worldwide: Not with high blood pressure or heart disease.
  • Kallawaya healing in Bolivia: Contains a lot of caffeine; not in the evening, not with heart complaints or in pregnancy.

Preparation

Roasted, ground seeds in drinks, powder or supplements. No dosage is given here.

Use in traditions

The Sateré-Mawé of the Amazon tell that the guarana plant sprouted from the eyes of a murdered child; the red fruits with black seeds look like eyes. They are regarded as the original cultivators of guarana. In Brazil guarana soda is a national drink.
