: The systematic study of the structural, physical, chemical, and biological properties of crude drugs obtained from natural sources.

The quality of a drug depends heavily on how it is harvested. Soil, climate, fertilizers. Plant Growth Regulators: Use of Auxins, Gibberellins.

: Create or look for slides that compare similar drugs (e.g., differentiating types of Cinchona bark). Active Recall

: Average number of stomata per square mm of epidermis.

Groups drugs according to their primary medical use or actions on the human body. : Digitalis, Arjuna. Purgatives : Senna, Castor oil. Carminatives : Fennel, Coriander. 5. Chemical Classification

: Compounds containing a sugar portion (glycone) bonded to a non-sugar organic molecule (aglycone or genin). The aglycone portion dictates the therapeutic effect. Major Subclasses :

: Composed of a sugar part (glycone) and a non-sugar organic part (aglycone).

: Isolated morphine from opium, marking the birth of modern phytochemistry. Module 2: Classification of Crude Drugs

This morphological classification is based on the source's physical form.

Derived from processing natural materials; lack cellular structure. Examples include juices (Aloe), latex (Opium), and gums (Acacia). 3. Taxonomical Classification

Screening natural environments for novel bioactive compounds.
