The present study aimed to evaluate the effect of a mouthwash containing a novel compound Chinese herbal medicine (artemisia capillaris, chrysanthemum, honeysuckle, angelica dahurica and asarum sieboldii) on oral ulcers and analyze sub chronic oral toxicity in rats. For efficacy study, mouthwash was administered on the ulcer area twice daily. Compared with the control group, healing time in the test group was shorter and the ulcer area was smaller. Histological analysis showed less inflammatory cell infiltration in the test group. For sub chronic oral toxicity, mouthwash was administered by oral gavage for 93 consecutive days. There were no significant differences in body weight, food consumption or organ coefficients between the test and control groups. Some parameters of haematology and serum chemistry were statistically different but within normal physiological ranges. No obvious abnormalities were found in the necropsies and histopathological observations. In conclusion, the compound Chinese herbal medicine mouthwash promoted oral ulcer healing in rats with no obvious sub chronic toxicity, providing a potential alternative therapeutic strategy for oral ulcers.
