Morphology:
- An upright, perennial herb to about 1 m tall. The rhizome (underground stem) is thick and ringed with the bases of old leaves. Turmeric only reproduces via its rhizomes.
- Leaves: Large, oblong, up to 1 m long, dark green on upper surface, pale green beneath. Each leafy shoot (pseudostem) bearing 8-12 leaves.
- Flowers: Yellow-white, borne on a spike-like stalk 10-15 cm long. Flowers are sterile and do not produce viable seed.
- Seeds: Small, ovoid, brown. Not viable.
Uses in Tradition systems of medicine
- Hot water extracts of the dried rhizome have been taken orally in Ayurvedic medicine to reduce inflammation.
- In Unani medicine, turmeric has been used for conditions such as liver obstruction and jaundice and has been applied externally for ulcers and inflammation
- A hot water extract of the dried rhizome taken orally was reputed to slow lactation, regulate fat metabolism, help symptoms of diabetes, diarrhoea and liver diseases, and as a tonic calm the stomach. The fresh juice taken regularly on an empty stomach has been used to prevent stomach disorders
- Externally, the dried rhizome has been applied to fresh wounds and insect stings and to help the healing process in chickenpox and smallpox.
Nutritional Properties
- Turmeric contains more than 300 naturally occurring components including beta-carotene, ascorbic acid (vitamin C), calcium, flavonoids, fiber, iron, niacin, potassium, zinc and other nutrients. But the chemical in turmeric linked to its most highly touted health effects is curcumin.

Turmeric powder is about 60–70% carbohydrates, 6–13% water, 6–8% protein, 5–10% fat, 3–7% dietary minerals, 3–7% essential oils, 2–7% dietary fiber, and 1–6% curcuminoids.
Phytochemical components of turmeric include diarylheptanoids, a class including numerous curcuminoids, such as curcumin, demethoxycurcumin, and bisdemethoxycurcumin.[8][4] Curcumin constitutes up to 3.14% of assayed commercial samples of turmeric powder (the average was 1.51%); curry powder contains much less (an average of 0.29%).[23] Some 34 essential oils are present in turmeric, among which turmerone, germacrone, atlantone, and zingiberene are major constituents
