Benefit of damiana herb
The libido-boosting power of damiana herb hasn't been tested in humans, although a damiana liquor - also spelled damiana liqueur - made from the damiana leaf has long been used as an aphrodisiac in Mexico. In animal studies, extracts of damiana herb had the benefit of speeding the mating behavior of "sexually sluggish" or impotent male rats. It had no effect on sexually potent rats. It is possible that this herb has additional benefits in humans that may be uncovered with further research.

Stimulating property of Turnera diffusa leaf and Pfaffia paniculata extracts - suma - on the sexual-behavior of male rats.
Arletti R.  University of Modena and Reggio Emilia, Italy.
Sexually potent and sexually sluggish/impotent male rats were treated orally with different amounts of damiana and Pfaffia paniculata fluid extracts. While having no effect on the copulatory behavior of sexually potent rats, both plant extracts--singly or in combination--improved the copulatory performance of sexually sluggish/impotent rats. The highest dose of either extract (1 ml/kg) (as well as the combination of 0.5 ml/kg of each extract) increased the percentage of rats achieving ejaculation and significantly reduced mount, intromission and ejaculation latencies, post-ejaculatory interval and intercopulatory interval. Neither extract affected locomotor activity. These results seem to support the folk reputation of damiana and Pfaffia paniculata as sexual stimulants.

Damiana leaf for anxiety
Anti-anxiety activity studies of various extracts of Turnera aphrodisiaca Ward.
J Herb Pharmacother. 2005;5(4):13-21. Kumar S, Sharma A. University Institute of Pharmaceutical Sciences, Panjab University, Chandigarh, 160 014, India.
Damian has been used traditionally for treatment of anxiety neurosis and as an aphrodisiac. Yet, the plant has never been subjected to systematic biological investigation. In the present investigation, petroleum ethe, chloroform, methanol, and water extracts of damiana aerial parts were evaluated for anti-anxiety activity in mice. Among all the extracts, only methanol exhibited significant anti-anxiety activity.

Damiana herb composition and mechanism of action
The chemical composition of damiana leaf is complex and all of the components have not been completely identified. However, the known make-up is 0.5-1% volatile oil, flavonoids, gonzalitosin, arbutin, tannin and damianin (a brown bitter substance). How damiana herb works as an aphrodisiac is currently not fully known. Many flavonoids are known to dilate blood vessels.
   Another study reports damiana leaf to contain alkaloids, cyanogenic glycosides, steroids, saponins, flavonoids, tannins, carbohydrates, and proteins.

Damiana side effects
Damiana herb appears to be safe when taken occasionally as a sex booster. Damiana has a long history of traditional medicinal and food use with no harmful consequences reported. However, no rigorous scientific studies have examined the effects of long-term use of this herb. For the time being, it would be safe to assume that when used in reasonable doses, damiana has not significant side effects.

Availability
Damiana is sold as bulk herb powder, damiana capsules, tea, and damiana liqueur. Damiana is often combined in aphrodisiac herbal products. Damiana tea is difficult to find, but you could search for it in a health food store.

The most abundant constituents of the oils were caryophyllene oxide, caryophyllene, delta-cadinene, elemene and 1,8-cineol.

Anti aromatase activity of damiana herb
Anti-aromatase activity of the constituents from damiana (Turnera diffusa).
J Ethnopharmacol. 2008 Dec 8; Zhao J, Dasmahapatra AK, Khan SI, Khan IA. Department of Pharmacognosy, School of Pharmacy, University of Mississippi, University, MS 38677, United States.
Damiana (Turnera diffusa Willd. Ex Schult) has traditionally been used as an herbal aphrodisiac. The study was aimed to investigate the anti-aromatse activity and the estrogenic activity of the constituents isolated from Turnera diffusa. The methanolic extract and 24 compounds isolated from the leaves of Turnera diffusa were evaluated for aromatase activity by using a tritiated-water release assay and for estrogenic activity. The methanolic extract demonstrated a dose-dependent inhibitory activity of the aromatase enzyme. Among the 24 tested compounds, pinocembrin and acacetin showed the most potent inhibition. Estrogenic activity was also observed in the extract and three compounds including apigenin 7-glucoside, Z-echinacin and pinocembrin. The extract of damiana herb and two isolated compounds pinocembrin and acacetin could significantly suppress aromatase activity. Moreover, apigenin 7-glucoside, Z-echinacin and pinocembrin showed estrogenic activity.

Additional damiana research
Investigation on the hypoglycaemic effects of extracts of four Mexican medicinal plants ( damiana herb ) in normal and alloxan-diabetic mice.
Phytother Res. 2002 Jun;16(4):383-6.
The hypoglycemic activities of four water ethanol extracts prepared from Bidens pilosa, Salvia officinalis, Psacalium peltatum and Turnera diffusa ( damiana ) were investigated in healthy and alloxan-diabetic mice. The extracts of Salvia officinalis significantly reduced the blood glucose of fasting normal mice after intraperitoneal administration. The extracts of P. peltatum and B. pilosa also significantly diminished glycemia in healthy mice. The administration of these three extracts to animals with severe hyperglycemia did not cause a significant decrease. The extracts of damiana did not show any hypoglycemic activity.

Historical uses of damiana herb
Historically, damiana has been used to relieve anxiety, nervousness, and mild depression, especially if these symptoms have a sexual component. The herb is also used as a general tonic to improve wellness. Damiana has also been used traditionally to improve digestion and to treat constipation, as a diuretic, as a treatment for cough, and in larger doses it is thought to have a mild laxative effect.
