RESUMEN
BACKGROUND: Candida albicans may cause vaginal infections in women. The aim of this study was to compare the antifungal effect of Lawsonia inermis with that of clotrimazole on rats. METHODS: A total of 35female Wistar rats were randomly assigned into 5groups. Four groups were infected vaginally with C. albicans and one group was not (negative control). The four infected groups received the following treatments: two groups received vaginal creams of 2% or 4% of L. inermis, one group received 1% clotrimazole and one infected group did not receive any treatment (positive control). The hydro-ethanolic henna extract was prepared from the powder of henna leaves using maceration method. Samples were taken for culture from the vaginae of all rats before the treatment, one and two weeks after treatment. An ANOVA test was used to analyze the data. RESULTS: Before the treatment, the mean colony forming units (CFU) was 213.6±10.08 and 334.42±20.32 in the 2% and 4% henna groups, respectively, 312.7±28.32 in the clotrimazole group, 233.85±8.15 in the positive control group, and zero in the negative control group. The mean CFUs were zero for all groups except for the 2% henna and positive control groups (P<0.001) one week after the treatment and zero in all groups except for the positive control group two weeks after the treatment (P<0.001). CONCLUSION: L. inermis (henna) in form of vaginal cream could treat C. albicans infections in female rats; however, 4% henna was more effective and had an effect similar to that of clotrimazole.
