MASHMALLOW - (Odor profile: popular fantasy note that recalls the American dessert, toasty and sweet). Marshmallow was first used as a medicinal substance made from the marshmallow plant, Althaea officinalis. This natural remedy was used to cure sore throats. Today it is mostly consumed as a delicacy. The traditional marshmallow is made from powdered marshmallow root, but most of the contemporary manufactured marshmallows use gelatin since the root is difficult to obtain.
