Lemongrass essential oil has a long history rooted in traditional medicine and aromatic practices, especially across South and Southeast Asia. The plant, scientifically known as Cymbopogon citratus, has been used for centuries in countries like India, Sri Lanka, and Thailand, where it was valued for its refreshing citrus aroma and therapeutic properties. Traditionally, it was used in herbal remedies to treat fever, digestive issues, and infections, and was often brewed into teas or applied as a natural antiseptic.

The extraction of lemongrass essential oil became more refined during the colonial period when steam distillation techniques were introduced and commercialized. By the 19th century, lemongrass oil had entered global trade, particularly through India, which became one of the largest producers and exporters. Its high citral content made it especially valuable in the perfume and flavoring industries, where it was used as a key ingredient in soaps, cosmetics, and beverages.
