Camphor tree bark comes from the camphor tree (Cinnamomum camphora) and has a distinctive fragrance and many uses.

Camphor tree bark is the dried bark of the camphor tree, a large evergreen tree in the laurel family (Lauraceae). The camphor tree is very commonly grown in the region south of the Yangtze River in China, often seen beside villages, along roadsides and in courtyard landscaping, and both its branches, leaves and bark carry a distinctive aromatic scent. People usually collect the bark when pruning or renewing trees, then dry it in the sun and store it for later use.

In appearance, camphor tree bark is mostly grayish brown or yellowish brown, often with longitudinal cracks on the surface, and is fairly thick with a slight toughness. When it is chopped or scraped open, it gives off a cool, camphor-like aroma, because it contains volatile oil compounds. Generally speaking, the stronger the scent, the richer the aromatic substances it contains.

In terms of application, the most common use of camphor tree bark is as a decoction for external use. In folk practice it is often boiled in water for washing or soaking the feet, to relieve discomfort such as itchy skin; some people also put the sun-dried bark in wardrobes or storage corners, using its fragrance to help repel insects and prevent moth damage. In addition, it can serve as a natural aromatic material for making sachets and other everyday small items.

It should be noted that although camphor tree bark has these traditional uses, taking it internally on your own is not recommended, and any medicinal use should be discussed with a professional physician. When collecting it, the method also matters, so avoid stripping large areas of bark and harming the tree itself. People with sensitive skin can do a small test patch before use, and should stop using it immediately if any discomfort occurs.
