All of the samples except K[3] [Tables 3 and 4] have not crossed their acceptable limit of heavy metals according to manufacturer doses for daily consumption. The total viable count [TVC] of the samples was ranged from nil to 1.92×10[4] CFU/ml and the total yeasts and moulds count were found nil to 1.68×10[2] CFU/ml. Salmonella or Escherichia coli was not present in any of the samples. The microbial quality of the herbal drugs was satisfactory limit according to United States Pharmacopoeia [2006][1]
