**8.4 Microscopic method**

Microscopy is a technique that is used to determine the structural, cellular and internal tissue features of plant material. It helps in identification and differentiation between two herbals that are similar in morphology [38, 39]. This is the commonly used technique, convenient, quick and non-destructive [40]. Microscopy involves varied techniques like compound, bright field, dark field, fluorescence and electron microscopy (Scanning Electron Microscopy known as SEM and Transmission Electron Microscopy known as TEM) that offer different features based upon the requirement.
