Cinnamomum camphora is known mainly for its wood. Camphor wood is rich in fragrance, and has the effects of repelling insects and moths, and repelling mildew and moisture. Historically, camphor is one of the famous trees in the south of the Yangtze River.

Cinnamomum Camphora is an evergreen tree species of Lauraceae and Lauraceae, also known as camphor. With a broad crown and dark green branches and leaves, it is an important four-side tree in the south. Camphor trees have a long life, and there are thousands of years old camphor in many places.
Cinnamomum Camphora leaves new leaves growing while old leaves fall off, so the leaves on the tree coexist. Its leaves are entire, slightly wavy, green on the front, shiny, and gray-green on the back, alternately on turquoise branches. The most special thing is its leaf veins, which are always bifurcated at a position 3 or 4 mm away from the base of the leaf, which is called "three outgoing veins from the base".
In spring, small green and yellow flowers are arranged in panicles and open one after another. Different from the strong fragrance of leaves and fruits, the flowers of Cinnamomum Camphora are delicate and elegant, with 6 perianths arranged in 2 rounds, which have 4 rounds of stamens, 3 in each round, but the three innermost rounds are degenerated, so it is usually seen. Stamens are 9. In the center of the small flower is a pistil.
Camphor wood is insect-proof because camphor is present in leaves and fruits, but it is mostly extracted from wood. Wood contains camphor oil, which is a mixture of various fatty acids synthesized in camphor tree, and camphor is a white or transparent waxy solid obtained by water distillation of camphor oil and cooling, and is a terpenoid organic compound. Due to the limited natural camphor resources, most of the "camphor" on the market is synthetic, which does not contain camphor ingredients, but has similar repellent and insecticidal activity, so it is used as a substitute for camphor. The furniture made of camphor wood is of high quality and expensive.
In autumn, the camphor fruit ripens, turning from green to purple-black. Fruit nearly spherical, attached to a cup-shaped receptacle. Cinnamomum Camphora is isolated from the shadows, and small crushed fruits are often seen.
