The purpose of this investigation was to determine if the tea plant Turnera diffusa, more commonly known as damiana, had a measurable effect on sexual behaviors in mice. Injections of damiana suspended in peanut oil (for test groups), or peanut oil alone (for control groups), were given to male and female mice. After two weeks, male mice were introduced to female mice following induction of estrus. Five sexual behaviors (number of mounts, intromissions, ejaculations, latency period, and lordosis) were monitored independently by two investigators in real time or using videotape. The results showed that the number of mounts and intromissions for the test mice were significantly higher than that of the control mice. Results from ejaculations, latency period, and lordosis were not statistically conclusive. No litters were obtained from test or control copulated females, suggesting that the peanut oil may have altered fertility. Accordingly, damiana does appear to exhibit some aphrodisiac properties in mice. Further studies may be done to determine the differential effects of damiana on male versus female mice.

Evaluation of Aphrodisiac Activity of Turnera aphrodisiaca
Suresh Kumar1 *, Reecha Madaan1 and Anupam Sharma
Turnera aphrodisiaca Ward (family Turneraceae) is reputed as an aphrodisiac throughout the world. Despite a long tradition of use as an aphrodisiac, no systematic work has ever been carried out on this plant to validate its traditional use. In the present investigation, various extracts (petroleum ether, chloroform, methanol and water), alkaloidal fraction, and volatile oil of T. aphrodisiaca were screened for aphrodisiac activity in mice. Mounting behaviour was taken as a parameter to screen aphrodisiac activity. Chloroform extract exhibited significant activity at a dose of 200 mg/kg, p.o. while methanol extract showed aphrodisiac activity at a lower dose, i.e., 50 mg/kg, p.o.. Volatile oil of T. aphrodisiaca was found to be devoid of aphrodisiac activity. Qualitative phytochemical screening showed the presence of alkaloids in chloroform and methanol extracts. Therefore, the alkaloidal fraction was isolated from aerial parts of T. aphrodisiaca, and tested for aphrodisiac activity at dose levels of 25, 50, 75, or 100 mg/kg, p.o. A dose dependent increase in activity was observed upon acute as well as subacute administration of alkaloidal fraction.
