Turmeric – an Aromatic Enhancer

Biological Description
Turmeric (botanical name Curcuma longa) belongs to a ginger (Zingiberacea) family and has been for centuries used as aromatic herb. It is a rhizomatous herbaceous perennial plant native to tropical South Asia.
The name of the plant comes from the Latin “terra merita” – “meritorious earth”, which refers to the colour of ground turmeric which resembles a mineral pigment. In many languages turmeric is just called a yellow root, and in Asian countries it is widely known as kunyit or haldi. Fragrant odour and a bitterish, slightly acrid taste leave exciting warmth in the mouth and colours the saliva yellow.
Turmeric is valued for its yellowish-brown tuberous underground stem that has a rough segmented skin. The interior of the rhizome looks bright yellow when powdered. The plant produces root-leaves that are about 2-3 feet long and carry conical clusters of pale yellow flowers.
Turmeric requires rather high temperatures, between 20 and 30 deg. C. and a considerable amount of annual rainfall. Plant’s rhizomes (source for propagation) are gathered annually, and re-seeded in the following season.

The rhizome is usually dried into powder which is taken by mouth or added as an ingredient into capsules, teas, or liquid extracts.
