This species is the main source of camphor, which is derived from chipped wood of the stems and roots and also from branchlets and leaves by steam distillation. It contains a fixed volatile oil. The plant is used medicinally as a stimulant, antispasmodic, antiseptic, and rubefacient. It also is used in the manufacture of celluloid. The wood is beautifully grained, light brownish, easily polished, and used for furniture, cabinets, and interior finish in buildings.

Cultivated in valleys and on mountain slopes. S of Chang Jiang river on mainland, Taiwan [Japan, Korea, Vietnam; introduced or cultivated in many countries around the world].
