Boracic acid, formerly termed the sedative salts of Homberg, has also been recommended to subdue amorous passions. This is true likewise of nitre, which, under this name, or that of Sal Prunelle and mineral crystal, has been much esteemed as an antiaphrodisiac. The use of this remedy according to Baldassar cured the man, who demanded so earnestly the removal of his testes, and whose case has already been mentioned: this salt was used because Prevatius, a physician at Pavia, having administered it to a man for an affection of the bladder rendered him impotent. The hemp and the willow have also been recommended: Etmuller believes particularly in the action of this latter; and recommends the extract of its leaves, and the sap obtained from its young branches in spring. (_Trait du bon choix des medicamens_, 1710. Lyons.)
But among all drugs, those which are the longest known, and which were most esteemed, are the _agnus castus_ or _vitex_, and the _nenuphar_. Human credulity is severely taxed, to believe what has been said as to the virtues of these articles. The Greek women, according to Dioscorides, slept during the festivals of Ceres, on the leaves of the agnus castus to preserve their chastity. Arnaud de Villeneuve states that an infallible mode of preserving the breast from all men’s attempts, is to carry a knife, the handle of which is made of this wood. Even now its leaves and seeds are used both externally and internally in monasteries to support more easily the rigors of celibacy. At present, however, no one believes in its virtues. The same is true of the nenuphar. Its reputation, as soothing the genital organs, belongs to the early periods of sciences. It is mentioned in Dioscorides and Galen, and its history is as fabulous as that of the agnus-castus. The list of antiaphrodisiacs would terminate here, if Montegre had not mentioned a tree called mairkonsia, which grew in the East Indies, and which was used by some fakirs to render themselves impotent. Every day those children, who are designed to be fakirs, swallow a small roll of its leaves: the dose is gradually increased, and at the age of twenty-five, the effect is irrevocably produced. This tree is yet to be known by scientific men. (_Dict. des Se. Med._, _Art. Continence_.)
