Camphor trees can be harvested and processed approximately 6 to 7 years after planting. The best time for harvesting is from late spring until early winter, as the tree should not be picked around the vernal equinox. Throughout the rest of the year, the leaves, bark, and roots can be collected, dried, and stored for future use. Fruits are typically harvested in early winter and then dried for medicinal or commercial 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 between red and green. This makes them an ideal choice for street trees, courtyard shade trees, and ornamental plantings in gardens or public spaces.
Camphor wood is also widely used in industry due to its high quality. It is commonly processed into camphor blocks, which serve as valuable raw materials. In traditional Chinese furniture, camphor wood is preferred for its durability and aesthetic appeal. Additionally, its natural aromatic compounds help repel odors, insects, and dust, making it useful for air purification and protection against pests.
Medicinally, various parts of the camphor tree—such as the roots, bark, leaves, and fruits—are used for their therapeutic properties. The trunk and roots contain 3% to 6% essential oil, with up to 8% found in the roots. The primary components include camphor, camphene, and scutellaria. The leaves contain about 0.2% to 1.5% camphor, which varies 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 stomachaches caused by cold, food stagnation, and bloating.
For example, 0.015 kg of root, when boiled in water, can help alleviate rheumatism and cold headaches. Applying the same solution to affected areas can also treat wet sores. Similarly, 0.009 to 0.015 kg of dried fruit, when prepared in the same way, helps with stomach colds, bloating, and digestive issues.
A mixture of 0.008 kg of camphor, 0.006 kg of pepper, and 0.05 to 0.06 kg of sesame oil, ground into a fine powder and applied externally, is effective in treating acne in children.
