The cool and aromatic camphor can be used to alleviate skin itching and irritation. There are two types of viable camphor trees that are used to extract camphor. The first is the common camphor tree from which the common variety of camphor and camphor oil are extracted. The second variety of camphor tree grows exclusively in borneo and is known as the borneo camphor tree. One of the most peculiar aspects of camphor oil extraction is that it can be achieved only when the tree is 50 years old. This is because there is a particular component in the camphor tree that needs to be activated before the oil can be extracted.
