ER 2020 Pharmacognosy: CHAPTER 1. Definition, history, present status and scope of Pharmacognosy 2 Hours

CHAPTER 1: Definition, History, Present Status and Scope of Pharmacognosy Notes for Diploma in Pharmacy (D.Pharm) Students 1. Meaning and Definition of Pharmacognosy The word Pharmacognosy is derived from two Greek words: Pharmakon = Drug Gnosis = Knowledge Definition Pharmacognosy is the branch of pharmacy that deals with the study of crude drugs obtained from natural sources such as: Plants Animals Minerals Marine organisms Microorganisms It includes the study of their: Source Identification Chemical constituents Collection Cultivation Uses Examples of Crude Drugs Drug Source Use Senna Plant Laxative Digitalis Plant Cardiotonic Honey Animal Nutritional and medicinal use Gelatin Animal Pharmaceutical aid Agar Marine algae Pharmaceutical aid Penicillin Microorganism Antibiotic Origin of the Term Pharmacognosy The term Pharmacognosy was first used by C.A. Seydler, a medical student from Germany, in 1815 in his doctoral thesis Analectica Pharmacognostica. 2. History of Pharmacognosy Human beings have used medicinal plants since ancient times. Before the invention of writing, knowledge about medicinal plants was passed from one generation to another through: Oral communication Signs and symbols Traditional practices Chinese System of Medicine Shen Nung (2700 BC) Known as the Father of Chinese Medicine. He studied hundreds of medicinal plants and recorded about 365 drugs in a book called Pen T-Sao. Examples Ephedra – Asthma Ginseng – General tonic Egyptian System of Medicine Ancient Egyptians maintained written records of medicines. Important Documents Ebers Papyrus Around 1550 BC Contains 800 prescriptions Mentions 700 medicinal drugs Edwin Smith Papyrus Contains surgical procedures and cosmetic preparations Common Drugs Used Aloe Castor oil Onion Opium Pomegranate These drugs are still used today. Indian System of Medicine (Ayurveda) India has one of the oldest medical systems called Ayurveda. Important Ayurvedic Texts 1. Charaka Samhita Deals mainly with medicine. 2. Sushruta Samhita Deals mainly with surgery. 3. Ashtanga Hridaya Deals with general medical knowledge. Around 1200 BC, more than 127 medicinal plants were described in Ayurvedic literature. Examples Turmeric – Antiseptic Neem – Antimicrobial Ashwagandha – Adaptogen Amla – Vitamin C source Greek Civilization The Greeks made major contributions to medicinal plant science. Hippocrates (460–370 BC) Known as the Father of Medicine. Studied human anatomy and physiology Used medicinal plants in treatment Described about 300–400 medicinal plants Aristotle (384–322 BC) Recorded properties of over 500 plants Dioscorides Published De Materia Medica in 78 AD. Described more than 600 medicinal plants Considered one of the most important books in medicinal plant history Galen (131–200 A.D) Developed many herbal formulations Introduced methods of drug preparation Modern Galenical Pharmacy is named after him. 3. Present Status of Pharmacognosy Earlier, Pharmacognosy was limited to the study of natural drugs. Today it has become a modern scientific discipline that includes: Study of Medicinal plants Animal drugs Marine drugs Biotechnology products Herbal medicines Natural products Modern Pharmacognosy Includes Cultivation Growing medicinal plants. Example: Senna Isabgol Collection and Processing Proper harvesting and storage. Identification Recognizing genuine drugs and detecting adulteration. Extraction and Isolation Obtaining active constituents. Examples: Caffeine from Coffee Quinine from Cinchona Digoxin from Digitalis Phytochemistry Study of plant chemicals. Examples: Alkaloids Glycosides Tannins Volatile oils Biological Screening Testing drugs for medicinal activity. Plant Biotechnology Production of medicinal compounds using tissue culture and genetic techniques. 4. Scope of Pharmacognosy Pharmacognosy has a wide scope in pharmacy and healthcare. 1. Drug Discovery Many modern medicines are obtained from plants. Examples: Drug Source Quinine Cinchona Digoxin Digitalis Atropine Belladonna Vincristine Vinca 2. Herbal Medicine Industry Increasing demand for: Herbal products Ayurvedic medicines Nutraceuticals Examples: Ashwagandha capsules Amla powder Turmeric tablets 3. Quality Control Helps identify: Adulterated drugs Substandard drugs Ensures safety and efficacy. 4. Research and Development Used in: New drug discovery Phytochemical research Biotechnology 5. Pharmaceutical Industry Provides raw materials for: Medicines Cosmetics Nutraceuticals Health supplements Importance of Pharmacognosy for D.Pharm Students Helps understand natural drugs. Provides knowledge of medicinal plants. Helps identify crude drugs. Forms the foundation for herbal medicine. Assists in drug discovery and research. Supports pharmaceutical and healthcare industries. Key Points to Remember ✅ Pharmacognosy means the study of drugs from natural sources. ✅ The term Pharmacognosy was introduced by C.A. Seydler (1815). ✅ Important ancient systems: Chinese, Egyptian, Indian, and Greek. ✅ Hippocrates is called the Father of Medicine. ✅ Dioscorides wrote De Materia Medica. ✅ Modern Pharmacognosy includes cultivation, identification, phytochemistry, extraction, and biotechnology. ✅ Pharmacognosy plays an important role in herbal medicine, drug discovery, research, and pharmaceutical industries.
