Comparing the Effects of Two Cream Formulations, Henna (Lawsonia inermis) and Clotrimazole, on Vaginal Candidiasis: A Randomized Controlled Trial

Abstract

Background: Vaginal candidiasis is the most prevalent infection among reproductive-aged women. The current treatment for this disorder includes azole compounds. Objectives: The aim of this study was to compare the effects of two creams, henna (Lawsonia inermis) and clotrimazole, on vaginal candidiasis. Methods: In this trial, 80 women with vaginal candidiasis were recruited and randomly assigned into two groups to receive either henna (n = 40) or clotrimazole (n = 40) for one week. The ethanol extract of henna was prepared. Vaginal discharge was cultured, and vaginal pH, colony formation, lactobacillus formation, and vaginitis subjective symptoms were evaluated before and one, two, and four weeks after the intervention. The chi-square test, independent t-test, and Generalized Estimating Equations were were used for analyzing the data using SPSS version 22. Results: After four weeks of the intervention, almost 90% of the women in the henna group declared no burning sensation, itching, discharge, irritation, or dyspareunia, while only 45%, 5%, 37.5%, 52.5%, and 27.5% of the participants in the clotrimazole group did not have these symptoms, respectively (P < 0.001). The means (SD) of colony formation were 290.85 (47.35) and 265.12 (37.46) in the henna and clotrimazole groups, respectively, at the baseline, which reduced to zero and 25.45 (25.09) in the 4th week of the intervention (P = 0.001). Compared with the clotrimazole group, there was a significant increase in the mean of lactobacillus formation and a significant decrease in vaginal pH in the henna group (P < 0.001). Conclusions: Henna vaginal cream could significantly reduce the symptoms of vaginal candidiasis, such as burning sensation, itching, discharge, irritation, and dyspareunia. Also, it could decrease colony formation and vaginal pH and increase lactobacillus formation.
