Rating (out of 5): 2

Lemongrass (Cymbopogon citratus) has been traditionally used in several cultures, particularly in Southeast Asia, to help alleviate symptoms of congestion and sinus discomfort. Folk remedies often include lemongrass tea, steam inhalation, or essential oil use for clearing nasal passages and easing breathing. The traditional rationale is based on its aromatic properties and the presence of compounds such as citral, which are believed to have mild antimicrobial and anti-inflammatory effects. However, when it comes to scientific validation for treating sinus congestion specifically, the evidence is limited. While some laboratory studies suggest that lemongrass oil exhibits antibacterial and antifungal activities, clinical research directly evaluating its efficacy for sinus congestion or respiratory tract infections is lacking. Most of the support for this use is therefore anecdotal or based on ethnomedicinal practices rather than robust clinical trials. As such, while lemongrass continues to be popular in traditional medicine for sinus issues, it should be considered an adjunct rather than a primary treatment, and anyone with persistent or severe congestion should seek appropriate medical evaluation.
