Sarcocephalus latifolius and Cnestis ferruginea are shrubs with heights of 5 to 8 m and 3 to 3.6 m, respectively, and are known to be powerful aphrodisiacs. Our aim was to evaluate the effect of aqueous extracts of their leaves on the body weight and relative weight of some androgen- dependent sex organs of male rats. For this purpose, the rats were subjected to an 8-day treatment. These extracts had no significant effect on either the body weight or the relative weight of the androgen-dependent secondary sex organs of the rats compared to the control over the 8-day treatment period. The leaves of Sarcocephalus latifolius and Cnestis ferruginea did not have any detectable androgenic properties during this period.
