Damiana is a low-growing plant that loves dry soil and plenty of rocks. It's native to Mexico, Central and South America. The flowers are yellow and small, and damiana bears a small sweet-smelling fruit as well. It's used as an herbal remedy to enhance sexual performance, as well as a very long list of other physical ailments.
Latin: Turnera diffusa or Turnera aphrodisiaca
Common names: damiana
Using in rituals
Damiana was used as an aphrodesiac tea by the Aztecs and the Mayans, and is still used today predominantly in love and sexuality spells. It's also used for fertility, but that is strictly a magickal association (not a medical one).
The leaves are used in magick, and can be worked in charm bags, incense or even in tea. If you make damiana tea, be prepared to add honey or sugar. I've heard it's quite bitter. One warning though, you should not consume damiana tea if you are pregnant or diabetic.
Damiana is also sometimes used as an incense to promote psychic dreams.
