Examples and health benefits
Start with the big picture
Natural products can vary in composition and quality, so pharmacognosy supports their use through authentication, phytochemical profiling, standardized extraction, contaminant checks, and formulation. It also helps assess safety and health claims using pharmacological, toxicological, and clinical evidence. The examples in this topic illustrate different areas of interest: curcumin is discussed for anti-inflammatory and antioxidant actions; omega-3 fatty acids for cardiovascular effects and other potential benefits; and probiotics for microbiota balance, intestinal-barrier support, and selected clinical uses. These examples are not interchangeable, and reported effects depend on the ingredient and evidence available. The fuller lesson places potential benefits alongside quality, safety, and sustainability considerations.
What you'll learn

- Identify the examples of curcumin, omega-3 fatty acids, and probiotics discussed.
- Summarize reported health effects associated with each example.
- Explain why evidence assessment and product quality matter when interpreting health claims.
