Anticancer Herbs and Phytoconstituents from Nature
Cancer represents one of the most significant global health challenges, characterized by uncontrolled cellular proliferation and high mortality rates. Conventional allopathic therapies, while effective to some degree, are often associated with severe side effects, high costs, and frequent recurrence. This has driven scientific interest toward natural alternatives—specifically herbs and phytoconstituents—that may offer preventive, prophylactic, and therapeutic benefits with better safety profiles and accessibility for broader populations.

Concepts of Molarity, Molality, and Normality for pharmaceutical professionals
Molarity is the number of moles of solute per liter of solution. It is the most commonly used concentration unit in pharmaceutical preparations.
Pharmaceutical Applications:
Preparation of intravenous (IV) fluids
Formulation of ophthalmic solutions
Standardization of titrants in analytical chemistry
Preparation of buffer solutions

Pharmaceutical Quality Control Hand Notes
Principle: HPLC is an analytical chemistry technique used to separate, identify, and quantify components in a mixture.
It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with solid adsorbent material.
Each component interacts differently with the adsorbent material, causing different flow rates and separation.
