Pharmacognosy
The study of raw pharmaceutical materials, or medications derived from natural sources including plants, microbes, and animals, is known as pharmacology. The study of mechanical, biological, environmental, and physical qualities is included in this. Because herbal remedies are derived from nature rather than being manufactured, it is thought that the human body responds to them more easily. The natural substance in the study might not be active in its original physical form; therefore, a chemical reaction or transformation might be necessary to change it into the active form. Although the active ingredient is often obtained directly from the plant, it can occasionally be synthesized to produce a chemical that closely resembles the plant extract.
