    Abstract:
    PURPOSE: The purpose of the study was to investigate the safety and efficacy of lemon juice and lemon grass (Cymbopogon citratus) in the treatment of oral thrush in HIV/AIDS patients when compared with the control group using gentian violet aqueous solution 0.5%. Oral thrush is a frequent complication of HIV infection. In the Moretele Hospice, due to financial constraints, the treatment routinely given to patients with oral thrush is either lemon juice directly into the mouth or a lemon grass infusion made from lemon grass (Cymbopogon citratus) grown and dried at the hospice. These two remedies have been found to be very efficacious therefore are used extensively. Gentian violet, the first line medication for oral thrush in South Africa, is not preferred by the primary health clinic patients due to the visible purple stain which leads them to being stigmatized as HIV-positive. Cymbopogon citratus and Citrus limon have known antifungal properties. METHODS: The study design was a randomised controlled trial. Ninety patients were randomly assigned to one of three groups: gentian violet, lemon juice or lemon grass. Inclusion criteria included being HIV-positive with a diagnosis of oral thrush. The study period was 11 days and patients were followed up every second day. International ethical principles were adhered to during the study. RESULTS: Of the 90 patients, 83 completed the study. In the intention-to-treat analysis, none of the p-values were significant therefore the null hypothesis could not be rejected. In the analysis of the participants who actually completed the trial, the lemon juice showed better results than the gentian violet aqueous solution 0.5% in the treatment of oral thrush in an HIV-positive population (p<0.02). The null hypothesis in terms of the lemon grass and gentian violet could also be rejected on the basis of the Chi-square test and the likelihood ratio test (p<0.05). CONCLUSIONS: Though the patient population was small, the use of lemon juice and lemon grass for the treatment of oral candidiasis in an HIV population was validated by the randomised controlled trial.
