The old males of ancient Greece were familiar with a range of decoctions meant to enhance their sexual performance. Nevertheless, no matter how tempting they may be, especially given the fact that they are at hand, do not try any of these at home and particularly not on your own.
In Hippocrates' time, for instance, the lubrication of the penis with a mixture of crushed pepper and honey was used to trigger long-lasting erections (that is, perhaps longer than 2 minutes...). There is no historical testimony with regard to the “side effects” of this procedure, but surely a tremulous shimmer of tears in the eyes and a few gasps were imminent.
Other ancient writings attest to the use of an ash dust resulted from the burning of a few deer tails mixed with wine that turned into a rather bad smelling paste in order to acquire a virility worthy of Hercule's envy. By applying this “ointment” onto the genitals, it was believed that the desire to fornicate would become unquenched (a reckless desire). On what was the opinion of women about the stench re-felt upon the approaching of a naked, archaic individual with eyes out of their orbit with impatience, there was found no historiographic clue.
Also, the Greeks believed in the miraculous effect of an Indian plant unidentified for the time being, that would have produced strong erections, was it rubbed onto the penis. It is not known whether the plant or the rubbing itself was the secret, but the chroniclers of the time talk about testimonies of soldiers who claimed that under the “influence” of the mysterious plant, they have achieved a series of remarkable sexual performances, translated into more than 12 orgasms produced to the women partners (their spouses). However, specialists remain circumspect in this regard. If the praise had come from the women directly involved in the respective achievements, things would probably have been more credible. This way, notwithstanding... everything remains at the “rubbing” stage.
