The therapeutic efficacy of a crude drug depends entirely on its agricultural and post-harvest handling. 1. Factors Influencing Cultivation
Quality control is an important aspect of modern pharmacognosy. This section covers the methods used to evaluate the purity, quality, and identity of crude drugs, including organoleptic evaluation (using senses), microscopic evaluation (identifying cellular and tissue characteristics), chemical evaluation (chemical tests and assays), and physical evaluation (determining moisture content, ash values, extractive values, etc.). pharmacognosy lecture notes ppt
Screening of natural products for new drug molecules (e.g., Paclitaxel for cancer, Artemisinin for malaria). The therapeutic efficacy of a crude drug depends
