Frequently Asked Questions (FAQ)
Q1. What is the scope of Pharmacognosy in D Pharma?
Pharmacognosy is the study of crude drugs derived from natural sources like plants, animals, and minerals. It covers everything from the history and distribution of these sources to their chemical constituents and therapeutic applications.
Q2. How are crude drugs classified in this course?
To make study systematic, crude drugs are classified using several methods detailed in Chapter 2:
Alphabetical: Based on name.
Morphological: Based on the part of the plant used (leaves, bark, etc.).
Pharmacological: Based on their therapeutic effect.
Chemical: Based on active constituents like alkaloids or glycosides.
Q3. How is the quality of natural drugs ensured?
Through Quality Control and Evaluation, as explained in Chapter 3. This involves checking for adulteration (substitution with inferior materials) using organoleptic, microscopic, and chemical testing methods.
Q4. What are "Herbs as Health Food"?
This section (Chapter 9) focuses on Nutraceuticals—natural products that provide health benefits beyond basic nutrition. Examples include probiotics, omega-3 fatty acids, spirulina, and antioxidants.
