Introduction: Mucositis is a common complication in around 40% of patients receiving chemotherapy which profoundly impact the quality of life. Despite the availability of many therapeutic agents that claim to prevent or reduce the severity of oral mucositis, no intervention that is completely successful at preventing oral mucositis exists. The present study aimed to demonstrate the effect of local honey on methotrexate-induced mucositis of the tongue. Materials and Methods: The study was done in albino rats (n = 24), divided into four groups: honey-normal saline group (H/NS), distilled water-NS group (DW/NS), DW-methotrexate group (DW/MTX), and H/MTX group. Local honey was given (2.5 g/kg) twice a daily for 8 days. NS or methotrexate (60 mg/kg) interrupted the experiment procedure on day 4. At day 8, rats were sacrificed and middle third of tongue was removed for preparation of histological slides. Slides were examined for inflammatory cell infiltration (ICI), cell vacuolization (CV), congested blood vessels (CBV), thickness of epithelium (both dorsal and ventral mucosa), and thickness keratin. Results: Statistically significant association was found between the groups for ICI and CV, χ2 (3) = 11.97, P= 0.003 for ICI, and χ2 (3) = 8.307, P= 0.023 for CV. Mean number of CBV per microscopic filed was 0.445, 0.389, 1.28, and 0.5 for H/NS, DW/NS, DW/MTX, and DW/H groups, respectively. Mean value of dorsal epithelial thickness (μm) was 96.78 ± 13.59, 100.50 ± 9.75, 75.53 ± 9.24, and 98.75 ± 10.92 for H/NS, DW/NS, DW/MTX, and DW/H groups, respectively. Mean value of ventral epithelial thickness (μm) was 70.45 ± 13.60, 58.38 ± 14.26, 37.04 ± 5.37, and 52.80 ± 7.97 for H/NS, DW/NS, DW/MTX, and DW/H groups, respectively. The thickness of epithelium of DW/MTX group was significantly different from other groups (P < 0.05). Conclusion: The present study demonstrated the palliative effect of local honey over the mucositis induced by the chemotherapeutic drug (methotrexate).
