CRITICAL ANALYSIS OF NIDANA AND SAMPRAPTHI OF AMAVATA WITH SPECIAL REFERENCE TO AUTOIMMUNITY
The human body is a conglomeration of dosha, dhatu and mala. Even though doshas are having opposite gunas they do not harm the body when in equilibrium state and it maintains the integrity of dushyas. Ama is a unique concept in Ayurveda which can be considered as improperly digested food or accumulated metabolic waste which is not expelled out of the body has a tremendous capacity to vitiate the dosha, dhatu and mala and is capable of producing various diseases. Amavata is a disease entity where ama and vata plays important role in the samprapthi of disease and viruddha ahara and chesta are considered to be the main causative factors. Autoimmunity is the system of immune responses of an organism against its healthy cells and tissues. Any disease that results from such an aberrant immune response is termed an autoimmune disease.
