Study Notes
Pharmacognosy: The Study of Medicinal Natural Resources
- Pharmacognosy is the study of medicines derived from natural sources, including plants, animals, and microorganisms.
- The word "pharmacognosy" originates from two Greek words: "pharmakon" (drug) and "gnosis" (knowledge).
- Active constituents are the compounds responsible for the therapeutic effects of medicinal substances.
- Crude drugs are derived from plant, animal, and mineral sources before undergoing extensive processing or modification.
Pharmacopoeia: A Guide to Official Drugs
- The Pharmacopoeia is a government-sanctioned publication containing a listing of all officially recognized drugs.
- It includes descriptions and requirements for ensuring the suitability of drugs for human use.
- A drug listed in the Pharmacopoeia is considered official.
- A drug not listed is considered unofficial.
