Cascarilla can refer to two main things: a white, powdered eggshell used for spiritual cleansing and protection, or the aromatic bark of the Croton eluteria tree from the Caribbean used in perfumes, incense, and traditional medicine. The eggshell form is finely ground and can be used to draw protective symbols, cleanse spaces, or for ritual baths, while the bark oil has a warm, woody, and spicy scent used in perfumery.
