Lemon grass also known as Cymbopogon citratus grows in tropical and subtropical regions across the globe. It is popularly found in India, but also grows in several areas of Africa including Sierra Leone and the frost-free regions in South Africa. Lemon grass is a perennial herb that can grow at heights up to 900 meters. It prospers in warm, humid climates with direct exposure to at least six hours of sunlight. Lemon grass requires well-drained, sandy loam soil with consistent moisture. The temperature should be maintained between 20-30oC for its growth. Since ancient times, lemon grass has been cultivated for its medicinal and aromatic properties. The oil is extracted from the leaves and stalks of the plant through steam distillation. The chemical composition of the resulting oil produced can vary depending on the plant’s age, geographical origin, method of extraction and genetic differences. The quality of the oil is checked by measuring its citral content and solubility in alcohol.
