Geographical Distributions

C. longa probably originated from South or South-East Asia, most probably from India. It is not known in a true wild state although in some places it appears to have become naturalised (e.g. in teak forests of East Java). C. longa has been grown in India since time immemorial. It reached China before the 7th century, East Africa in the 8th century and West Africa in the 13th century. It was introduced into Jamaica in the 18th century. Presently turmeric is widely cultivated throughout the tropics but cultivation on a considerable scale is largely confined to India and South-East Asia.
