A shrub found throughout the Americas. Some sexual enhancement lubricants use an extract from the leaves of damiana as an active ingredient. It is sometimes listed as damiana, tumera aphrodisiaca extract, or passifloraceae (the plant family’s name).

Damiana is traditionally used as a treatment for low sex drive. It has been shown to inhibit anxiety, and animal tests support the assertion that damiana is an effective sexual enhancement substance. Because of its relaxant effects, the damiana plant is illegal in the United States, but the plant’s extracts are legal in some circumstances.
