Study Notes
Pharmacognosy: Scope and History
- Pharmacognosy is the scientific study of crude drugs, focusing on their structural, physical, chemical, and biological properties.
- The term "pharmacognosy" was coined in 1815 by C.A. Seydler, combining the Greek words "pharmakon" (drug) and "gnosis" (knowledge).
- The American Society of Pharmacognosy defines pharmacognosy as the study of the physical, chemical, biochemical, and biological properties of drugs, drug substances, or potential drugs of natural origin.
Alternative Systems of Medicine
- Ayurveda: An ancient Indian system of medicine emphasizing holistic health, using herbs, minerals, and lifestyle practices.
- Siddha: A traditional Tamil medicinal system with roots in Ayurveda and focusing on the body's energy channels (nadis).
- Unani: A system of medicine originating in ancient Greece and practiced in many Muslim-majority countries incorporating elements of Ayurveda and Greek medicine.
- Homeopathy: A system of medicine based on the principle "like cures like," employing diluted substances to stimulate the body's healing response.

Crude Drug Classification
- Alphabetical Classification: Arranging drugs alphabetically, useful for quick reference but not based on scientific principles.
- Morphological Classification: Grouping drugs based on their physical appearance (organized, unorganized, or parts of a plant). Organized drugs are easily identifiable (e.g., leaves, flowers, roots) while unorganized drugs lack structure (e.g., gums, resins).
- Taxonomic Classification: Categorizing drugs based on their botanical origin, helping to identify species and potential for medicinal applications.
- Biological or Pharmacological Classification: Grouping drugs based on their similar therapeutic effects or pharmacological activities, but does not provide information on chemistry or taxonomy.
- Chemical Classification: Categorizing based on the primary chemical constituents present in the drugs, offering insights into potential pharmacological actions.
- Chemotaxonomic Classification: Combining chemical and taxonomic properties to understand the evolutionary relationships between plants and their active compounds.
- Serotaxonomical Classification: Classifying plants based on their serological reactions, using immune system responses to identify species.
Sources of Crude Drugs
- Plant: Plants are the oldest and still primary source of many drugs.
- Animal: While less common, animal sources provide some essential drugs (e.g., insulin from pig pancreas).
- Mineral: Minerals (like iron, zinc, and magnesium) are crucial for human health and may be included in medications or supplements.
Pharmacognosy: Scope and Impact
- Advancement of Science: Pharmacognosy has contributed significantly to the advancement of natural, physical, and pharmaceutical sciences.
- Modernization of Cultivation: Knowledge gained from pharmacognosy has led to improvements in cultivating medicinal plants, ensuring quality control and meeting demand.
- New Drug Discoveries: Pharmacognosy forms a vital link between pharmacology and medicinal chemistry, aiding in the isolation of purified natural drugs for potential therapeutic use.
- Quality Control and Standardization: Establishing quality control procedures and standards for crude drugs is crucial for ensuring the safety and efficacy of herbal medicines.
- Economic Impact: Pharmacognosy plays a role in understanding the economic aspects of herbal industries by focusing on the market potential of various crude drugs.
- Global Health: The World Health Organization (WHO) recognizes the importance of herbal medicines, estimating that 80% of the world's population relies on them for primary healthcare.
