A common lubricant ingredient created by concentrating oils from the paullinia cupana plant, more commonly known as guarana.

The guarana plant naturally produces a large amount of caffeine, which can improve endurance when taken in significant doses. However, while guarana seed extract is a safe lubricant ingredient, it is not clear whether it improves sexual endurance when applied topically. People who are sensitive to caffeine should avoid lubricants with guarana extract
