Medicinal plants have been widely used for immune system disorders in different cultures and traditional medicine systems around the world from antiquity to the present day. With the discovery of antibiotics, antibiotics cured infections in patients. However, with the overuse of antibiotics, many antibiotics have become ineffective even in simple infections. This has created a serious public health problem today and has increased the importance of the use of medicinal plants. Interest in natural and organic approaches, traditional knowledge and cultural heritage, alternative and complementary therapies, easy accessibility and the potential for fewer side effects are the main reasons for the use of medicinal plants. Some plants contain natural compounds with antioxidant, antimicrobial, anti-inflammatory, immunostimulant, adaptogenic and immune-enhancing properties. The use of medicinal plants based on scientific data briefly tries to determine the therapeutic potential and appropriate use of plants. In this study, plants used effectively on the immune system and diseases were reviewed in the literature and their effects on the immune system were investigated.
