Background: Plants are easily prone towards microbial infections on exposure to microorganisms and pathogens. In order to defense, plants produce low molecular weight secondary metabolites which were later known as “Phytoalexins”. These molecules have vast therapeutic potential also. Purpose: The purpose of this review is to explore the phytoalexins and their pharmacological effects.Methods: The data included from the articles were published from Web of Science, PubMed, Medline, Scopus, and Embase by using relevant keywords including plants possessing phytoalexins and their specific biological applications.Results: The review insights the potential of phytoalexins in various diseases and to explore have phytoalexins applications in human health and disease control. Conclusions: On the basis of this review we may be conclude that phytoalexins have tremendous potential in the treatment and prevention of various life-threatening diseases like diabetes mellitus, cancer, brain damage, and heart attack.

Rheumatoid arthritis, an autoimmune inflammatory disorder is characterized by progressive cartilage erosion leading to joint destruction, pain, stiffness, and swelling. Although the etiology of the disease is unknown, genetic changes due to factors such as environmental agents, immune response towards infectious agents influence rheumatoid arthritis. Earlier NSAIDs were the first choice of drugs for the treatment of disease but due to having certain side effects and limitations, herbal therapies which possess higher efficacy and safety are now in demand. There are hundreds of plants that have phytoconstituents that exhibit anti-inflammatory activity. A combination of plants is used to make polyherbal formulations that act synergistically to give anti-arthritic activity. The review is about the botanicals and traditional formulations which have been clinically tested for the treatment of Rheumatoid arthritis.
