Objectives: Objective of this study was to comparatively evaluate the quality of three marketed brands of Triphala tablets (Brand T 1 and T 2 ) and capsules (Brand T 3 ) which are available in Sri Lanka. Materials and Methods: This laboratory based experimental qualitative study was done among three brands of Triphala. Phytochemical screening was carried out for all those brands. Physicochemical tests were also performed to determine pH, moisture content, and loss on ignition, ash values and extractive values. Data were analysed by using Statistical Package of Social Sciences 23. Results: Physicochemical tests revealed that all three brands failed to comply with pharmacopoeial limits at least in one physicochemical test. According to ANOVA test, there was significant difference between results of physicochemical tests of marketed brands of Triphala. Conclusion: All three Triphala brands did not meet the quality standards. Quality of herbal medicine marketed in Sri Lanka should be monitored and regularized by relevant authorities.
