The small tree or shrub, Sambucus Nigra, grows all over Europe wild or planted. It is appreciated for its flowers which are used in medicine for their mild diuretic effect, for their berries which serve as a food or a preserve and finally for the soft marrow which Ends use in certain carvings and for industrial purposes. The dried flowers are steam distilled in Hungary, Germany and France. The essential oil is known in France as essence de sureau, The oil is solid at room temperature and it has a very peculiar, intensely sweet, honey like, faintly animal and unpleasantly nauseating odor.
