Botanical Information
Turmeric is a perennial herbaceous plant growing up to 1 meter tall. It has trumpet-shaped, yellow flowers and rhizomes (underground stems) that are deep orange inside. The rhizomes are harvested, boiled, dried, and ground into the bright yellow powder known the world over. Its active compound is curcumin.
Origin & History
Native to the Indian subcontinent and Southeast Asia, turmeric has been cultivated in India for over 4,000 years. Sanskrit medical treatises from 250 BCE mention it as a major Ayurvedic herb. It traveled to China by 700 CE, East Africa by 800 CE, and Europe via Arab traders in the medieval era.

In Ayurveda, turmeric (Haridra) balances all three doshas — Vata, Pitta, and Kapha. It is considered Ushna (heating), Tikta-Katu rasa (bitter-pungent taste), and Laghu (light). Used for skin diseases, diabetes (Prameha), liver health, and as a blood purifier (Rakta shodhaka). The classical formulation 'Haridra Khanda' treats allergies and skin issues.

Storage & Buying Guide
