Medicinal preparations:


Damiana can be used in tinctures, teas and herbal extracts, among other preparations.


Not commonly used for topical concerns.


Do not use if pregnant or nursing. Do not administer to children under 18 and consult with a doctor prior to use if you are taking medications, diabetic/hypoglycemic, or have diarrhea. Its blood sugar lowering effect makes it unsafe for use in the two weeks leading up to surgery. Damiana is included in some blends meant to create a “legal high” when smoked. Marketed as “synthetic cannabis” or “Black Mambo”, the ill effects resulting from this misuse has caused it to become a prohibited plant in some countries, such as the UK.

Large doses (200 grams) have been known to cause poisoning, due to the presence of cyanogenic glycosides. Only use this herb under the guidance of a qualified healthcare professional with knowledge in herbal medicine dosing. Also note that long-term dosage can interfere with iron absorption.

I suggest consulting a pharmacist or physician before starting any herbal supplement if you are taking a prescription medication or have serious underlying health concerns.

Energetic/traditional use:

Damiana has both male and female connotations, as it assists in the libido and reproductive health of both sexes. Mayans were particularly fond of its sexual properties, and it was one of the top aphrodisiacs used by their civilization. It is traditionally used in the Mexican liqueur, Triple Sec. People in Central and South America use the leaves to make incense and tea.

Energetically, damiana is known to restore strength and vitality, and to reconnect the body and mind. It’s useful for those who try to ignore their physical urges, or neglect their body.  It also helps those who dwell on their worries, or feel inadequate. It restores confidence and motivation.
