Pharmacology of Natural Anti-Inflammatory Agents: From Traditional Medicine to Modern Therapeutics

Numerous significant health issues, including heart disease, metabolic abnormalities, brain degeneration, and immune system failure, are largely caused by persistent inflammation. Conventional anti-inflammatory medications frequently reduce symptoms but pose serious issues for long-term care, such as negative side effects and diminishing efficacy over time. Because they often have lower safety risks, natural chemicals have emerged as possible substitutes. This chapter sheds light on the pharmacological actions of the main classes of plant-based anti-inflammatory compounds. Curcumin and resveratrol are examples of polyphenolic compounds that alter important inflammatory signaling pathways, specifically nuclear factor kappa B (NF-κB), mitogen-activated protein kinase (MAPK), and nuclear factor erythroid 2-related factor 2 (Nrf2), offering both anti-inflammatory and antioxidant protection. Flavonoids stabilize the oxidative equilibrium of cells while reducing the generation of pro-inflammatory cytokines and inhibiting enzymes such as lipoxygenase (LOX) and cyclooxygenase (COX). Terpenoids decrease immune cell tissue penetration and control the activity of inflammatory enzymes, whereas alkaloids limit not only the development of inflammasome complexes but also the release of inflammatory messengers. Early research has shown intriguing anti-inflammatory capabilities for coumarins, especially in sophisticated nanoparticle formulations. According to current research, problems include poor drug absorption and adverse pharmacokinetic properties that reduce the efficacy of treatment. Innovative distribution methods, enhanced formulations, and structural changes are some of the solutions. This chapter highlights the modern pharmacological significance of natural anti-inflammatory compounds and the need for ongoing development toward safe, effective, multi-targeted therapies. It does this by using experimental and clinical evidence to show how these compounds can be used as complementary treatment options for inflammatory diseases.
