The musquelibet is about the size of a roe deer. In its groin an abscess grows from accumulated fluids. When it is ripe, the animal beats and rubs it against a tree, loosening the abscess, and the sap runs down and condenses there and hardens, and this substance is called musk.

The musk produced by the musquelibet is effective against syncope and weakness of the heart, brain, liver and stomach.
