Guarana is a South American fruit that strangely enough resembles the human eye. This fruit contains four times the amount of caffeine than coffee beans and is one of the prime ingredients in energy drinks like Monster, Red Bull and Rockstar.

In fact, during the 17th century, the Jesuit missionaries noted that this herb gave members of the Amazon tribe so much energy that while hunting, they could go days without feeling hungry. Now today, guarana is still used to boost energy and promote weight loss, but the advantages don’t just stop there.

Botanical Name and Family of Guarana

Guarana is botanically known as Paullinia cupana. It belongs to the Sapindaceae or the Soapberry family and has been referred to as Brazilian cocoa and Zoom.
