Turnera diffusa
Damiana
This shrub native to Southwest Texas in the U.S. and Central America, South America, and Mexico has a long history of use as an aphrodisiac. The leaves have traditionally been made into a tea and incense, which was used by native people of Central and South America for its relaxing effects. Spanish missionaries first recorded that the Mexican Indians drank Damiana tea mixed with sugar for use as an aphrodisiac. It is also an ingredient in a traditional Mexican Liqueur, which is sometimes used as a substitute for Triple Sec in Margaritas.
