Food use
In the United States, castoreum as a food additive is considered by the Food and Drug Administration (FDA) to be generally recognized as safe,[11] often referenced simply as a "natural flavoring" in products' lists of ingredients. While it can be used in both foods and beverages as a vanilla, raspberry and strawberry flavoring,[12] the annual industry consumption is around 300 pounds.[13]
Castoreum has been traditionally used in Scandinavia for flavoring snaps commonly referred to as "Bäverhojt".[14]

Perfume
In perfume-making, the term castoreum is more liberally applied to denote the resinoid extract resulting from the dried and alcohol tinctured beaver castor.[6] The dried beaver castor sacs are generally aged for two or more years to mellow and for their raw harshness to dissipate. In perfumery, castoreum has largely been used as an animalic note suggesting leather, compounded with other ingredients including top, middle, and base notes as a composition. Some classic perfumes incorporating castor are Emeraude, Chanel Antaeus, Cuir de Russie, Magie Noire, Lancôme Caractère, Hechter Madame, Givenchy III, Shalimar, and many "leather" themed compositions.[7]
