Lemongrass (Cymbopogon citratus) has a long history of use in traditional medicine systems, particularly in Southeast Asia, for treating various ailments, including respiratory congestion. In folk remedies, lemongrass is often brewed as a tea or used in steam inhalations to help clear nasal passages and ease breathing. The aromatic nature of lemongrass, due to its essential oils such as citral and limonene, is thought to provide a soothing effect on the respiratory tract. However, the evidence supporting its efficacy for congestion is largely anecdotal and based on traditional use rather than rigorous scientific studies.

While lemongrass does possess some antimicrobial, anti-inflammatory, and antioxidant properties according to laboratory studies, there is a lack of well-designed clinical trials specifically investigating its effect on upper respiratory congestion in humans. Most of the scientific literature focuses on its general antimicrobial and anti-inflammatory effects, which could theoretically help with symptoms of congestion, but direct evidence is minimal. Overall, the use of lemongrass for congestion is primarily justified by traditional practices, with scientific support limited to indirect mechanisms rather than clinical outcomes.
