The immune system plays a crucial role in protecting the human body from various infectious agents and diseases. In recent years, interest in natural remedies has significantly increased due to their fewer side effects and broad therapeutic potential. This study explores the role of natural extracts—derived from medicinal plants and herbs—in strengthening the immune system. Emphasis is placed on the bioactive compounds found in these extracts, such as flavonoids, alkaloids, polysaccharides, and essential oils, which exhibit immunomodulatory, antioxidant, and anti-inflammatory effects. The research also reviews current scientific findings and clinical studies supporting the efficacy of natural extracts in enhancing both innate and adaptive immunity. This topic is of particular importance in the context of global health challenges, where natural solutions can complement conventional medicine in preventing and managing immune-related disorders.
