Objectives: We investigated the effects of allicin on nasal mucosa via an experimental study. Methods: In the study, 16 male New Zealand Albino (2.5-4.5 kg) rabbits were used. The right nasal passages of the 8 rabbits were included in the control group (Group 1, n = 8), and the right nasal passages of the 8 different rabbits were included in the study group (Group 2, n = 8). In the study group (Group 2), a Merocel tampon soaked in Allicin (Alli Tech; Dulwich Health) (0.5 mg/kg). In the control group (Group 1), a Merocel tampon soaked in serum physiologic was placed in the right nasal passage for 3 days (first to third days of the study). On the fourth day, nasal mucosa was excised and histopathological examinations were performed. Results: Our results showed that there were no significant differences in terms of bleeding, congestion, inflammation, calcification, and seromucous gland density between the study and control groups (P > .05). In light microscopic evaluation, moderate density of lymphocytic cells beneath the surface epithelium and, further down, seromucous gland structures, dense seromucous glands, and occasional ductal structures were observed in the study group. Congested vascular structures beneath the respiratory epithelium and adjacent to a thick-walled vascular structure, coarse calcification is observed in the control group. Conclusion: It has been demonstrated that the Allicin-soaked Merocel pack does not have adverse effects on rabbit nasal mucosa, and it does not lead to mucosal bleeding, congestion, inflammation, and calcification, and changes in the seromucous gland density. Considering the antibacterial and antiviral effects of allicin, it is appropriate to plan research in humans to evaluate its use in nasal packs applied during epistaxis, septoplasty, rhinoplasty, and endoscopic sinus surgery.
