Incense in Tibet is believed to have come from India over 1,300 years ago and has been made in a time-honored method ever since. Ancient Bon texts also speak of cleansing the air with smoke, which alludes to the burning of incense. Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to Kusum flower, ashwagandha, and shahi jeera.
