Cinnamon is an evergreen shrub or small tree with dark, leathery, aromatic leaves. In cultivation, young trees are cut back twice a year and sucker shoots develop from the roots. These long slender shoots furnish the bark that is the commercial product. The leaves are used in tea. A very popular culinary spice. The oil is used in medicine as a carminative, antiseptic, astringent and as the source of cinnamon extract.
