Study Notes
Pharmacognosy Overview
- Pharmacognosy is the study of medicinal drugs derived from plants, animals, and minerals.
- It involves the discovery, development, and use of medicinal substances from natural sources.
Crude Drugs
- Crude drugs in pharmacognosy refer to unprocessed or partially processed medicinal substances obtained from natural sources, such as plants, animals, and minerals.
- Examples of crude drugs include dried plants, roots, bark, leaves, and other plant parts.
Natural Products vs. Synthetic Compounds
- Natural products (NP) are substances produced by living organisms, such as plants, animals, and microorganisms.
- Synthetic compounds are man-made substances created in a laboratory using chemical reactions.
Identification of Medicinal Plants
- Pharmacognosy involves the identification of medicinal plant species through botanical characteristics, such as leaf shape, flower color, and stem texture.
- Identification also involves chemical analysis of the plant's active constituents to determine its medicinal properties.
Unorganized Drugs
- Unorganized drugs in pharmacognosy refer to medicinal substances obtained from natural sources that are not standardized or processed into a uniform product.
- Examples of unorganized drugs include folk medicines, herbal remedies, and traditional medicines that have not been standardized or regulated.
