The tree has a number of uses. It has been important in papermaking in Thailand for seven hundred years. Virtually all of the ancient Thai documents still in existence are written on the bark of this tree. The Buddhist texts and official records from before the twentieth century in Thailand are known as khoi books. The paper is durable even in the local high-humidity climate. It does not burn easily and it is resistant to yellowing and insect damage. Today other fiber sources are used to make paper and khoi fibers are used primarily by artisans who produce paper using traditional techniques.
