The preparation is a poly herbal formulation containing threemedicinal plants amalaki, bibhitaki and haritaki. Triphala itself is used as an ingredient in other formulations like Pancaguna Taila, Triphala guggul etc. Different manufacturers collect fruits from different habitats. High concentration of heavy metals in formulation may be due to collection of fruits fromdifferent habitats like farmlandswhere there is excess use of fertilizers or from the plants growing near the highways where the plants are exposed to automobile pollutants. Five heavy metals Cu, Zn, Pb, Ni, and Hg which are contributed through various sources from the atmosphere and automobiles were analysed in Triphala of different manufacturers and from Triphala in-house (prepared in laboratory) by Optical Emission Spectroscopy which uses the technique of Inductively coupled plasma. ICP-OES is one of the analysis techniques of trace elements. Out of the Triphala samples analysed of different manufacturers, total heavymetal concentration was found to be maximuminManufacturer No.3 (M3) andminimumin Triphala in-house.
