Evaluation of a novel natural drop for treatment of chronic rhinosinusitis without nasal polyps: a single blind randomized trial

Background The present study investigated the effectiveness of a Pimpinella anisum–based herbal medicine for treating chronic rhinosinusitis (CRS) without polyps in comparison to fluticasone nasal spray, in a single‐blinded randomized trial. Methods Patients with CRS without nasal polyps were randomly assigned into 2 treatment groups: individuals in the first group (n = 26) received 2 drops of a P. anisum–based herbal medicine (Sinupim) in each nostril every 12 hours, while those in the second group (n = 22) received 2 puffs of fluticasone nasal spray in each nostril every 12 hours. Both groups used their designated treatments for 4 weeks. Patients were evaluated by the 22‐item Sino‐Nasal Outcome Test (SNOT‐22) at the start of the trial and after the completion of their treatment. Results Although both treatments were effective in reducing patients’ symptoms, there were significantly better results in the Sinupim group based on the SNOT‐22 evaluation. Mean changes in computed tomography (CT) scan scoring in Sinupim and fluticasone groups before and after treatment were 2.22 ± 2.94 and 0.76 ± 1.39, respectively, which was significant within both groups (p < 0.05). Postnasal drip and nasal obstruction were more significantly improved in the Sinupim group. Conclusion A P. anisum–based herbal medicine may be an effective treatment for sinusitis without polyps. However, its wide acceptance needs further investigation.
