Phytochemical Evaluations

Pharmacognosy is the structural and scientific study of unprocessed medications that have an animal vegetable or mineral source. The term identification of crude drugs by organoleptic methods refers to the assessment of a drug based on sensory characteristics such as scent colour taste and texture as well as gross morphology. The sensory characteristics of medicines include noting their colour aroma taste and texture. Some medications like cinnamon and clove have characteristics like stone cells and volatile oils. The distinctive taste of drugs like ginger capsicum and liquorice can be used to identify them.
