Summary

This study looked at whether nasal drops made from Pistacia lentiscus oil (a natural plant oil) can prevent chronic sinusitis from coming back. 100 adults with frequent sinus infections were followed for a year. One group used the oil drops plus a saltwater rinse, while the other used only the saltwater rinse. The main goal was to see if symptoms improved, and the study also checked safety and side effects.
