About
Curcuma zanthorrhiza, known as temulawak, Java ginger, Javanese ginger, or Javanese turmeric is a plant species, belonging to the ginger family. It is known in Javanese as temulawak, in Sundanese as koneng gede (large turmeric) and in Madurese as temu labak. The scientific name is sometimes written as Curcuma xanthorrhiza, but this is an orthographical variant.
This plant originated from Indonesia, more specifically from Java island, out of which it spread to several places in the biogeographical region Malesia. Currently, most of the temu lawak is cultivated in Indonesia, Malaysia, Thailand, and the Philippines. Outside of South East Asia, cultivars may be found also in China, Indochina, Barbados, India, Japan, Korea, the United States and some countries in Europe.
