The photo above was taken at the turmeric farm, Temanggung regency in Central Java during the dry season at the end of July 2019. Turmeric plant is a perennial, rhizomatous, herbaceous plant native to the Indian subcontinent and Southeast Asia including Indonesia. Turmeric root or rhizome has been long using in old Ayurvedic medicine and its main constituent curcumin has been reported in modern medicine as an essential medicinal therapy with some clinical evidences.

Curcumin also can be used to reduce the memory lost, although there are insufficient evidences for Alzheimer’s disease and mental function.

Turmeric is also used to flavor or color mustard, butters, and cheeses. Curcumin the main constituent of the turmeric is sold as an herbal supplement, cosmetics ingredient, food flavoring, food coloring, and as a natural food preservative.

Turmeric plant (Curcuma longa or Curcuma domesticus) is flowering plant the member of the ginger family (Zingiberaceae). As the other members of ginger family, commercial turmeric plants propagate through their rhizomes not from the seed. Tumeric plants are harvested each year for their rhizomes, some for propagation in the following season and some for consumption.

Volcanic soil with the warm temperature (20 – 30°C) and moderate to considerable amount of annual rainfall (1000 – 2000mm), also the additional of rich organic matter in compost are the keys for the turmeric plant to thrive. As their property easy to be used and useful in nature, turmeric plants are easy growing plants with high density in optimum conditions.

There is an old proverb originally from Austronesian languages, is a huge group of various peoples in Southeast Asia, Taiwan, Oceania and Madagascar mentioned that “as turmeric with lime”. The meaning is in any positive and proactive relationship, hopefully it is easy and intimate to blend, combine, and agree.
