Role of Medicinal Plants in Autoimmune Diseases: Concepts, Perspectives, and Utilization provides comprehensive knowledge of autoimmune diseases and the role of various medicinal plant products in their treatment. The book discusses the immune system as a group of complex biological structures and processes in an organism which gives protection against a wide range of pathogenic organisms while simultaneously distinguishing these pathogens from the organism’s own healthy cells and tissues, thus maintaining homeostasis in the body. It has been an age-old practice to use extracts and other parts of various plants in treating many diseases. Several plants contain various pharmacologically active substances which can be used to treat different diseases.
