Rich, earthy, mossy: the scent of a Northern European forest. Botanical name: Evernia prunastri.
Oakmoss was used in perfumery as early as the 16th century. Baskets filled with it were found in the ancient royal tombs of Egypt, but whether it was intended for perfume or for food is not known. Oakmoss contains a starchy edible substance. A mixture of acids extracted from it is used in drugs for treating external wounds and infections. Source
