Plants based medicines have been in use since eons for general
health as well as to cure a specific illness. Eurycoma longifolia (Tongkat
Ali), a South East Asian plant has been used as an aphrodisiac and isknown to increase male sexual prowess and be effective in treating
ED (Ang et al., 2001). Based on experimental studies in rats,
Eurycoma longifolia was found to increase the number and frequency
of sexual intercourse episodes, duration of sexual performance and
ejaculations (Ang et al., 2001, 2000). Unfortunately, studies on are
lacking to support its aphrodisiac activity. Lepidium meyenii Walp.
also known as Maca, is a root vegetable cultivated in the central
Peruvian Andes and is known for its aphrodisiac activities. Research
on male rats and mice indicates that Maca positively affects sexual
behavior parameters such as the latency to and frequency of mounting
and latency to ejaculation after 15 day of treatment (Cicero et at.,
2001)
