Joss sticks are a type of incense used in many East Asian and Southeast Asian countries, traditionally burned before a Chinese religious image, idol or shrine. They can also be burned in front of a door, or open window as an offering to heaven, or devas. In modern days, joss sticks can be used for any purpose, such as to enhance the smell of a room, or to light fire crackers.
Joss sticks are religious materials in China, India, Bangladesh, Vietnam, Thailand, Taiwan, Myanmar, Cambodia, Philippines, Korea, and Japan.
The word “joss” is derived from the Latin deus (god) via Portuguese.
