3MICROBIOLOGICAL QUALITY ASSESSMENT OF COMMERCIALLY AVAILABLE MEDICINAL PLANTS IN PESHAWAR CITY, PAKISTAN
Abstract Medicinal plants naturally harbor a variety of microorganisms. Besides, representing a direct health hazard to the consumer, these contaminated materials can cause the spoilage of pharmaceuticals and traditional preparations to which they are added. Assessment of microbiological loads of plants to assure safety and quality is therefore worth investigation.
