Guarana
Alternative names: Paullinia cupana
Latin name: Paullinia cupana
Occurrence: Amazon Forest (Brazil, Ecuador, Venezuela, Colombia)
Guarana is known as a natural panacea to South American natives. Due to the high content of its active substances, it has a positive effect on various areas of the human body. Nowadays, Guarana is mainly sought after for its stimulating effects. It also helps handle diarrhoea, migraines, fatigue, impotence and premenstrual syndrome.
Interesting fact: The caffeine content in guarana can be up to 4x higher than in a regular cup of coffee, and its stimulating effect lasts longer - without the weird jitters - due to its slow absorption.
