Guarana is a Brazilian plant native to the Amazon basin. Also known as Paullina cupana, it’s a climbing plant prized for its fruit. Amazonian tribes have used guarana for centuries for its therapeutic properties. It contains an impressive range of stimulants and is rich in caffeine, which can reduce fatigue and improve focus. Low doses of guarana can improve mood, learning and memory. Guarana has antioxidant and antimicrobial properties, making it a common additive in cosmetic products. It may aid blood flow to your skin, reduce damage linked to aging and minimize undesirable features, such as saggy skin and wrinkles.
