Qurse pudina (QP), a poly herbal formulation which is used for treatment of constipation and gas problems in both Unani and Ayurvedic System of Indian Medicine. In the present article, an attempt has been made to standardize of the poly herbal formulation QP. The QP was standardized with the help of microscopic, physico-chemical and contamination evaluation. Study revealed that total bacterial and fungal count and Staphylococcus aureus were found under limit, while E. Coli was absent in the formulation. Pesticide residues, aflatoxin and toxic metals such as cadmium and mercury were not found in the formulation. Lead (0.75 mg/kg) and arsenic (0.50 mg/kg) were found under limit. The present outcome from contamination results suggest that QP is a good polyherbal formulation without showing any contamination or toxicity. The data evolved in the present work will aid in identifying the raw drugs used in finished product and will help to fix the scientific standards for QP. Manuscript profile
