Lemongrass, also known as citronella grass, yields an essential oil called citronella oil—sometimes referred to as lemongrass oil or palmarosa oil. This oil is obtained through steam distillation of citronella grass and appears as a pale yellow liquid with a rich, pungent aroma reminiscent of Sichuan pepper. Its main components include citral, geraniol, and citronellol. Just by its distinctive Sichuan-pepper-like fragrance, you can tell that this ingredient has a fairly strong flavor. To put it another way, citronella grass is just as indispensable in Chinese cuisine as Sichuan peppercorns are in Sichuan-style dishes.

Unlike other essential oils, lemongrass essential oil is not typically used for massage or aromatherapy. On the other hand, it serves as a key raw material for synthesizing a variety of everyday floral fragrances—such as apple and strawberry—and edible flavors like cinnamon and ginger. The novel aroma of lemongrass has a lemon-like scent, making it suitable for use as a food flavoring without the need for additional additives.

Unlike lemongrass, which is primarily used in food, lemongrass oil has a distinctive aroma that many insects find unpleasant and tend to avoid. As a result, lemongrass oil is often used as an insect-repellent agent in tropical regions. I wonder whether it smells better than mothballs.

With the expansion of industrialization, citronella oil can also be synthesized chemically and has become a mainstay in the essential oil market thanks to its low production costs. China is also a major exporter of citronella oil. In 2011, China reached a peak in citronella oil exports, with export revenues exceeding 700 million U.S. dollars. However, in the past two years, due to the weakening of the North American market, China's citronella oil exports have declined. By 2014, export revenues had fallen to just 200 million U.S. dollars.
