Incense has played an important role in many of the world's great religions. In India Incense sticks are lighted daily in every house. Incense comes from tree resins, as well as some flowers, seeds, roots, and barks that are aromatic. The ancient religions associated their gods with the natural environment, and fragrant plant materials were believed to drive away demons and encourage the gods to appear on earth; they also had the practical aspect of banishing disagreeable odors. Fashion is intensely linked to scents, and designers include signature scents to evoke the spirit of their clothes. That perfume originated from incense shows in the word itself; per and fumum mean through and smoke in Latin.
