Damiana (Turnera diffusa) is a wild shrub that grows in Mexico, Central America, and the West Indies. The leaf and stem are used to make medicine.
Damiana contains chemicals that might improve stomach health and reduce ulcers. It might also have effects like an aphrodisiac.
People use damiana for depression;indigestion&obesity, sexual dysfunction, and many other conditions, but there is no good scientific evidence to support these uses.
