Curcuma Longa (Turmeric)

Turmeric, known as Haldi in Hindi and Haridra in Sanskrit, is one of the most important plants in traditional medicine and Indian kitchens. It belongs to the Zingiberaceae family, which is the same family as ginger. Turmeric is widely used in India, China, and Southeast Asia as a spice, food preservative, natural coloring agent, and herbal medicine.

The bright yellow color of turmeric is what gives dishes like curry and even mustard their golden glow. But beyond its culinary uses, turmeric has been valued for centuries in Ayurvedic, Chinese, and folk medicine for its powerful healing properties.

Common Names

• English: Turmeric

• Hindi: Haldi

• Sanskrit: Haridra

It is known by different names across India’s regional languages and Asian countries.

Botanical Description

Turmeric is a perennial, herbaceous plant that can grow up to 1 meter (3.3 feet) tall. It has:

• Highly branched, aromatic, yellow to orange-colored underground stems (called rhizomes)

• Large, oblong to elliptical green leaves, which are arranged in two rows and can grow up to 115 cm long and 45 cm wide

From the leaf sheaths, the plant forms a false stem, and the rhizomes are the most valuable part, harvested for medicinal and culinary use.

Where It Grows

Turmeric naturally grows in the warm, tropical regions of India, Nepal, Thailand, and Southeast Asia. India alone has around 40-45 species of turmeric plants, making it one of the richest regions for this plant. Other Asian countries also have their local wild varieties of turmeric.

Phytochemistry: What’s Inside Turmeric?

Turmeric powder is made from dried rhizomes and contains:

• 60-70% carbohydrates

• 6-8% protein

• 5-10% fat

• 3-7% minerals and essential oils

• 1-6% curcuminoids (the active medicinal compounds)

Among these, curcumin is the most important, giving turmeric its deep yellow color and most of its healing properties. Other phytochemicals include demethoxycurcumin, bisdemethoxycurcumin, and over 30 types of essential oils like turmerone, zingiberene, and germacrone.
