| | "Damiana is claimed to be a stimulant and aphrodisia... It is considered useful for countering fatigue, overwork, depression and stress. In aromatherapy, the essential oil is considered to be uplifting. In Mexico, an infusion is drunk like ordinary black tea...\\ |
| | Arbutin is known as a diuretic and urinary tract desinfectant but the levels in damiana are considered too low to be therapeutically significant." \\ |

| | Folia (Ramuli) Damianae, the dried leaves of T.diffusa, own a citric scent and a aromatic bitter taste. They contain essential oil (0.5-0.9%), tannins (3.5%) and bitter substances (up to 7%). The infusion is used in Mexico as (heart) tonic, stimulant, aphrodisiac and diuretic. \\ |

| "Plants of damiana(Turnera diffusa Willd.) are important to industry and traditional medicine in semi-arid climates. Although all populations are wild, no reports have been made previously of their different phenotypes. Here, we investigated various micromorphological characteristics and the levels of essential oils in two phenotypes. Oils were extracted from fresh leaves via hydrodistillation and analyzed by gas chromatography-mass spectrometry. Morphological analyses were conducted under a stereoscopic microscope and with a scanning electron microscope. In all, 56 compounds were identified, enabling us to distinguish separate phenotypes. DL1 plants mainly contained 1,8-cineole, 10-epi-gamma-eudesmol, and guaiol; whereas those of DL2 primarily constituted ß-pinene, ß-caryophyllene oxide, cadinene, and α-cadinol. These two phenotypes also differed in their morphologies, with DL1 leaves showing elevated essential oil concentrations, but lacking trichomes. In contrast, the DL2 plants had lower contents of essential oils but did possess trichomes on their abaxial and adaxial leaf surfaces." \\ | "Plants of damiana(Turnera diffusa Willd.) are important to industry and traditional medicine in semi-arid climates.

| "Turnera diffusa and sildenafil (both at 10 mg/kg) facilitated expression of male sexual behavior by shortening mainly ejaculation latency. Treatments also facilitated the number of discharges in the ejaculatory motor pattern as well as the number of ejaculatory motor patterns and its associated penile erections. l-NAME prevented the pro-sexual effects of treatments on both experimental models. Besides, the extract of Turnera diffusa (10 mg/kg) produced an anxiolytic-like effect in male rats without affecting ambulation." \\ | "Turnera diffusa and sildenafil (both at 10 mg/kg) facilitated expression of male sexual behavior by shortening mainly ejaculation latency.
