White or Indian Sandalwood, known in Japanese as byakudan, has been treasured for centuries around the world for its soothing fragrance. Sandalwood, together with agarwood, form the basis of traditional Japanese incense. The evergreen tree is native across southeast Asia, particularly in India, and is used in Ayuverdic as well as Chinese medicine to treat a variety of ailments. Incense is made using the aromatic heartwood, which can take more than 60 years to cultivate. The dense, durable core is impervious to insects, hence it is regarded as a protective tree whose scent can drive away evil spirits, and so was used in the building of temples and religious statues from India to Japan, besides being an effective mosquito repellant. Sandalwood from Mysore in the South of India is particularly prized for its aroma and in Japanese is referred to as rōzan (老山 “old mountain”) sandalwood.
