Cinnamomum tamala is a moderate sized evergreen tree which is the source of tejpat leaves and the Indian cassia bark. It is distributed in tropical and sub-tropical Himalayas, therefore also is grown wildly in Chure range of Nepal at altitude of 1500 m. The leaves of a tree closely related to cinnamon but are little known elsewhere.
In ancient Greece and Rome, the leaves were used to prepare fragrant oil, called Oleum Malabathri, and were therefore valuable. The leaves are mentioned in the 1st century Greek text Periplus Maris Erytraei as one of the major exports of the Tamil kingdoms of southern India. The name is also used in mediaeval texts to describe the dried leaves of a number of trees of the genus Cinnamomum, which were thought to have medicinal properties.
