Powdered Crude Drug Microscopy of Leaves and Bark is a complete resource for the microscopic identification and authentication of herbal drugs. Various microscopic techniques, structural and cellular features of herbs are examined for the determination of botanical origin. This method is useful for identifying species with similar morphological characters. Today, there are a variety of methods available to authenticate herbal drugs, ranging from simple morphological examination to physical and chemical analysis, and DNA molecular biology. Due to cost, powder microscopy is the most practical method for primary authentication. Botanical microscopy is a unique, valuable, rapid and cost effective assessment tool, and plays an important role in the authentication and assessment of medicinal plants. This book is an essential resource for students and researchers involved in the study of plants and natural products.
