Basil (Ocimum basilicum) has a long history of use in traditional medicine systems such as Ayurveda and traditional Chinese medicine, where it is believed to support respiratory health, including the sinuses. Traditional uses include the application of basil leaves or inhalation of basil-infused steam to help relieve sinus congestion and inflammation. The rationale is often attributed to basil's aromatic volatile oils, such as eugenol and linalool, which are thought to have mild anti-inflammatory and antimicrobial properties.

However, scientific evidence specifically supporting basil's effectiveness for sinus health is limited. Some in vitro and animal studies have demonstrated anti-inflammatory and antimicrobial effects of basil extracts and essential oils, which could theoretically benefit the sinuses by reducing inflammation or combating infection. Despite these findings, there is a lack of robust human clinical trials directly examining basil's efficacy for sinus conditions such as sinusitis or allergic rhinitis. Most of the evidence remains anecdotal or based on traditional practices rather than modern scientific validation.

In summary, basil's use for sinus support is primarily justified by traditional use, with only limited preliminary scientific rationale. More research, particularly well-designed human trials, would be needed to confirm any direct benefits for sinus health.
