Cinnamomum verum (Ceylon True Cinnamon; කුරුඳු)

Cinnamomum verum is part of the catalog of ayurvedic medicinal plants of Sri Lanka.

Cinnamomum verum, called true cinnamon tree or Ceylon cinnamon tree, is a small evergreen tree belonging to the family Lauraceae, native to Sri Lanka.The inner bark of several other Cinnamomum species is also used to make cinnamon, but C. verum has a subtler flavor that makes it preferred for certain recipes.

Cinnamomum verum trees are 10–15 metres (30–50 feet) tall. The leaves are ovate-oblong in shape and 7–18 cm (3–7 inches) long. The flowers, which are arranged in panicles, have a greenish color and a distinct odour. The fruit is a purple 1-cm drupe containing a single seed.

The old botanical synonym for the tree, Cinnamomum zeylanicum, is derived from Sri Lanka's former name, Ceylon. Sri Lanka still produces 80–90%[6] of the world's supply of C. verum, which is also cultivated on a commercial scale in the Seychelles, Madagascar & Tanzania.

Many rheumatic disorders of chronic, intermittent pain (including joint pain, neck pain or back pain) have historically been caused by infectious diseases. Their etiology was unknown until the 20th century and not treatable, like Lyme disease (in the Northern, Northeastern, and Appalachians of the US), coccidiomycosis or valley fever (in the Western US), and chikungunya in India, Africa, and South America. Postinfectious arthritis, also known as reactive arthritis, and rheumatic fever are other examples.
