In most cancer patients, chemotherapy-induced oral mucositis (OM) is a frequent side effect, leading to low quality of life and delay in therapy. The aim of this study was to evaluate the effects of Onchung-eum, a well-known herbal prescription in traditional medicine comprising 8 herbs that has long been used for skin diseases, on 5-fluorouracil (5-FU)-induced OM in human pharyngeal cells and golden Syrian hamsters. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, and reactive oxygen species production were measured in vitro. The effects of Onchung-eum on OM of hamster cheek pouches induced by 5-FU were evaluated histologically and using TUNEL assay. In addition, the expression of nuclear factor-kappa B, caspase-3, and pro-inflammatory cytokines were measured by immunoblotting and immunohistochemistry. Significantly increased cell viability was observed in the Onchung-eum-treated groups compared with the 5-FU-treated control group. In 500 and 1000 mg/kg Onchung-eum-treated groups, the damaged epithelial layers in the cheek pouches of hamsters were significantly recovered. Moreover, at all concentrations, cell death in the cheek pouches of hamsters in the Onchung-eum-treated groups significantly decreased. The expression of pro-inflammatory cytokines, nuclear factor-kappa B, and caspase-3 also significantly decreased in Onchung-eum-treated groups at 500 and 1000 mg/kg. In conclusion, this study revealed that Onchung-eum can be used to treat chemotherapy-induced OM. However, further studies are required to understand the underlying mechanisms.
