The basic ingredients of an incense stick are bamboo sticks, paste (generally made of charcoal powder or wood powder and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients – which traditionally would be a powder of mixed ground ingredients, though more commonly is a solvent of perfumes and/or essential oils. After the base paste has been applied to the bamboo stick, it is either, in the traditional method, while still moist, immediately rolled into the flavourant, or, more commonly, left in the sun for several days to dry, and then dipped into the scented solvent.
