Camphor trees can be harvested and processed 6 to 7 years after planting. The best time for harvesting is from late spring until early autumn, as it's not advisable to collect the plant around the vernal equinox. Throughout the rest of the year, the leaves and fruits can be gathered, dried, and stored for future use. The roots and bark can be collected at any time during the year and are then dried for later application. Fruits should be picked in early winter and properly dried for medicinal or industrial purposes.
In terms of landscaping, camphor trees are highly valued for their dense foliage, beautiful appearance, and pleasant fragrance. They remain evergreen throughout the year, and in autumn, some of their leaves turn red, creating a striking contrast with the green foliage. This makes them an excellent choice for street trees, courtyard shade trees, and ornamental plants. Whether planted individually or in clusters, they add aesthetic value to any landscape.
Camphor wood is also widely used in industry due to its high quality. The stems, branches, roots, and leaves can all be processed into camphor blocks, which serve as valuable raw materials. In traditional Chinese furniture making, camphor wood is prized for its durability and fine grain. Additionally, its natural aroma helps repel odors, pests, and dust, making it ideal for use in homes during warmer months.
Medicinally, various parts of the camphor tree are used. The roots, bark, leaves, and fruits contain essential oils, with the trunk and roots containing up to 8% volatile oil. The primary components include camphor, camphene, and scutellaria. The leaves contain about 0.2% to 1.5% camphor, depending on the season.
The root is known for its ability to relieve rheumatic pain and cold-induced headaches. The bark and leaves are often used topically to treat dry skin and itching. The fruit is effective in treating stomach colds, food stagnation, and bloating.
For rheumatism and cold headaches, 0.015 kg of root is decocted in water and taken internally. For wet sores, the affected area can be washed with the same decoction. To treat stomach discomfort and bloating, 0.009–0.015 kg of dried fruit is decocted and consumed. A mixture of 0.008 kg of camphor, 0.006 kg of pepper, and 0.05–0.06 kg of sesame oil, ground into a powder, is applied externally to treat acne in children.
