Damiana

Damiana (Turnera diffusa, syn. Turnera aphrodisiaca) is a shrub native to Central and South America. It belongs to the family Turneraceae.

Blooming with small yellow flowers, the shrub has an odor somewhat like chamomile or cannabis sativa, which is due to an oil present in the plant. The leaves have traditionally been made into a tea which was used by native people of Central and South America for its reputed aphrodisiac effects.

Damiana is also a European name. In the country of Bulgaria it is simply a female version of Damian. In Greece the name Damiana refers to a person who is tame and subdued. Additionally, the name Damiana is somewhat common in Latino/Spanish locations.
