Abstract
The role of herbs in enhancing immune function has garnered substantial attention due to their natural and holistic benefits. This review paper investigates ten herbs—Echinacea, Elderberry, Astragalus, Garlic, Ginger, Turmeric, Andrographis, Holy Basil (Tulsi), Licorice Root, and Ginseng—known for their immune-boosting properties. A systematic approach was employed, including comprehensive literature searches, data extraction, critical appraisal, and synthesis of findings from peer-reviewed studies. The results demonstrate that these herbs offer diverse health benefits, such as boosting immune cell activity, reducing inflammation, and providing antioxidant support. Echinacea and Elderberry are highlighted for their effectiveness in mitigating respiratory infections, while Garlic and Ginger are noted for their antimicrobial properties. The review also provides practical recommendations on dosages, usage methods (e.g., teas, tinctures, supplements), and safety precautions. This article serves as a thorough guide for integrating these herbs into daily health routines, particularly useful during cold and flu seasons, to enhance immune resilience and overall well-being.
