A young man who had taken a large dose of cantharides in some wine, felt at first, a sort of violent itching, accompanied by great irritation in the bladder, and soon after he suffered greatly from extreme heat, together with an intolerable strangury. Bleeding, emulsions, injections, and opium preparations afforded not the slightest relief. Groenvelt prescribed two scruples of camphor in two boluses. The first dose partly mitigated the pains, and the second one removed them entirely. The remedies which were first administered had, no doubt, weakened the inflammation, and the strangury being no longer kept up by the spasmodic state of the urinary apparatus, camphor sufficed to effect a cure. Burton asserts the value of camphor as an anti-aphrodisiac, and says that when fastened to the parts of generation, or carried in the breeches, it renders the virile member flaccid. Agnus castus, so called from the down on its surface resembling that upon the skin of a lamb, and from its supposed anti-aphrodisiacal qualities, was in great repute among the Athenians, whose women, during the celebration of the Thesmophoria, or feasts and sacrifices in honour of Ceres or Thesmophoria, the legislatress, abstained for some days from all the pleasures of love, separating themselves entirely for that time from the men. It was also usual with them during the solemnities to strew their beds with agnus castus, fleabane, and other herbs as were supposed to have the power of expelling amorous inclinations. Arnaud de Villeneuve[197] exaggerates, almost to a ridiculous degree, the virtue of the agnus castus, asserting as he does, that the surest way to preserve chastity, is to carry about the person, a knife with a handle made of its wood. It was also, and perhaps is still, much used by the monks, who made an emulsion of its seeds steeped in Nenuphar water, and of which they daily drank a portion, wearing at the same time round their loins a girdle made of its branches. Lettuce has also the reputation of being anti-aphrodisiacal. Lobel instances the case of an English nobleman who had long been desirous of having an heir to his estates, but all in vain. Being, however, at length advised to discontinue eating lettuces, of which he was particularly fond, his wishes were gratified by his being blessed with a numerous offspring. The desire for coition was also supposed to be diminished by drinking a decoction of the pounded leaves of the willow. Vervain, dried coriander, and also mustard, drunk in a fluid state, are also said to prevent the erection of the penis. Alexander Benedictus declares that a topaz having been previously rubbed against the right testicle of a wolf, then steeped in oil or in rose water and worn as a ring, induces a disgust for venereal pleasures, as does also, if we may credit the same sapient physiologist, a powder made of dried frog. The two following prescriptions are also said to be of great efficacy:--
