B.Pharm. Sem.-IV | Pharmacognosy and Phytochemistry-I | Crude Drug


A crude drug is a natural substance, derived from plants, animals, or minerals, that is used in its raw, unrefined form for medicinal purposes. It has not been subjected to any significant chemical processing or purification, and is typically collected and dried. Crude drugs are the foundation of many traditional medicines and are also used in modern drug development.


🔹 Introduction
Crude drugs are natural substances obtained from plants, animals, and minerals that are used in the unprocessed or minimally processed form for medicinal purposes. They form the foundation of pharmacognosy and are studied for their source, morphology, chemical composition, and therapeutic uses.

🔹 Classification of Crude Drugs

Based on Origin

Plant origin (leaves, bark, seeds, roots, flowers)

Animal origin (honey, wool fat, gelatin)

Mineral origin (chalk, kaolin, talc)

Based on Therapeutic Use

Laxatives, analgesics, antiseptics, cardiotonics, etc.

Based on Chemical Nature

Carbohydrates, glycosides, alkaloids, tannins, volatile oils, resins, etc.

🔹 Key Points

Crude drugs are the primary source of modern medicines and phytopharmaceuticals.

Their quality, purity, and identity must be established before medicinal use.

Study of crude drugs includes pharmacognostic evaluation like organoleptic, microscopic, and chemical tests.
