Abstract
In present study five drug samples viz Zingiber officinalis, Boerhaavia diffusa, Glycerrhiza glabara, Terminalia arjuna, Terminalia chebula were analysed for microbial load(Total bacterial count and total yeast and mould count) and for specific pathogenic bacteria (E.coli, Salmonella spp, Staphylococcus aureus, Pseudomonas aeruginosa) as per WHO norms(Anonymous 1998). Total bacterial load is higher in four samples of herbal drugs (Zingiber officinalis, Boerhaavia diffusa, Glycerrhiza glabara, Terminalia chebula). The total Yeast and mould count in all five samples is beyond the prescribed limits of WHO while Specific pathogenic bacteria are absent in all five sample of herbal drugs.
