Drug evaluation confirms the identity, quality, and purity of a sample. This prevents accidental substitution or intentional adulteration. Types of Evaluation : Measured by loss on drying or Karl Fischer titration

Pharmacognosy is defined as "the study of the physical, chemical, biochemical and biological properties of drugs, drug substances or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources". It covers the identification, extraction, and analysis of bioactive compounds used for therapeutic purposes.
