197. Muscus: i.e. a spice; hot and dry in the second degree; Platearius says what musk is, i.e., a liquid substance found in boils occurring on certain animals in India; those animals are like goats, and it is near their knees that the boils occur. There are three colours, a black colour completely, a black colour in part, and an off-red colour, the best being the off-red. If the smell of it be applied to the nose, it will help with swooning and every weakness of the heart; it has the comforting virtue because of being aromatic, and the dissolving virtue because of its own qualities. If musk be applied to the nose regularly, it will help with displacement of the uterus, and with every weakness of the animal virtue. If musk be placed in the vagina, it will induce conception. Item, if musk be put in oil until it melts, and wool or cotton be dipped in it and put in the vagina, it does the same; if it be held in the mouth, it will stop a bad smell on the breath. If musk be rubbed between the palms of your hands in a stream or lake, the fish will come to you, especially the pike. If powder of musk be rubbed on the armpits, it will help with their foulness, called hircus, as we said before.
