Dhoops are an extruded incense, lacking a core bamboo stick. Many dhoops have very concentrated scents and put out a lot of smoke when burned. The most well-known dhoop is probably Chandan Dhoop. It contains a high percentage of sandalwood.India is the world's main incense producing country,and is a healthy exporter to other countries (though export sales have
been troubled by increasing costs of the raw materials, and by other
factors, such as Western countries buying unperfumed sticks, and by
Indian companies producing fakes or imitations).Incense burning has taken place in India for thousands of years, and
India exported the idea to China and Japan, and other Asian countries.
