199. Mandragora: i.e. the root of a herb that is cold and dry; the degree is not to be found in the authorities; there are two sorts of it, a feminine sort and a masculine sort; some of the doctors say that it is to be found under gallows, and that it is the semen that drips from the gallows to the ground which causes it to come into being, and its root is in the shape of a human being. If the skin of this root be preserved, it will retain its efficacy for three years. It has the repercussive, clotting and killing virtues. If it be placed under a person's head, it will provoke sleep. If the powder of this root together with white of egg be applied to the forehead, it will help with headache, and it will provoke sleep likewise. If this powder be given in wine to drink, it will repercuss the hot internal apostumes. Many other merits of Mandragora are described in the books, but we will omit them here.
