Pharmacognosy is the study of natural medicines.
Pharmacognosy deals with chemistry, biochemistry, isolation, structure determination and bioavaibility and pharmacological aspects of natural sources, natural products and natural compounds. In analytical Pharmacognosy, the microscopical features, anatomical and morphological caharcateristics of herbal drugs preparaed from pedicianl plants are studied, in addition natural chemical pure compounds are isolatede and the chemical formulae are determined, and the biologically active compounds are searched for their pharmacological and biochemical properties.
Reverse pharmacognosy aims at finding biological targets for natural compounds by virtual or real screening and identifying natural resources that contain the active molecules.
Synthetic products are man made. Natural products can be found in nature.
