Lemongrass (Cymbopogon citratus) belongs to the grass family Poaceae. It’s a tall, perennial plant native to tropical and subtropical regions. The plant features long, slender leaves that grow in dense clumps.

Lemongrass thrives in warm, humid climates and is widely cultivated in Southeast Asia, India, and parts of Africa. The plant can reach heights of up to 3 meters (10 feet) under optimal conditions.

Its leaves contain essential oils responsible for the herb’s characteristic lemon-like scent and flavor. These oils are concentrated in the lower, white portion of the stalk.

Culinary History in Asian Cuisine

Lemongrass has been a staple in Southeast Asian cooking for centuries. Its use dates back to ancient times in countries like Thailand, Vietnam, and Malaysia.

In traditional Thai cuisine, lemongrass is a key ingredient in soups like tom yum and various curry pastes. Vietnamese cooks often use it to flavor pho and other broths.

Indonesian and Malaysian cuisines incorporate lemongrass in marinades, stir-fries, and seafood dishes. The herb’s popularity has spread beyond Southeast Asia, finding its way into fusion cuisines worldwide.

Lemongrass is also valued for its medicinal properties in many Asian cultures. It’s commonly used in teas and folk remedies for digestive issues and stress relief.
