Cinnamon is a small evergreen tree 10–15 meters tall, native to Sri Lanka and South India. The bark is widely used as a spice due to its distinct odour. In India it is also known as “Daalchini”. The leaves are ovate-oblong in shape, 7–18 cm long. The flowers, which are arranged in panicles, have a greenish color, and have a distinct odor. The fruit is a purple 1 cm berry containing a single seed.
Cinnamon is among the earliest, most popular spices used by mankind. The commercial presentation of cinnamon is the dried inner bark of the tree, or the milled bark. The bark oil, bark oleoresin, and leaf oil are important value-added products.
