| All the types of ''kushtha'' are caused due to vitiation of ''tridosha'' with involvement of skin, blood, lymph and muscular issue. ''Kushtha'' is often translated in English as leprosy, which is not correct because of absence of Mycobacterium leprae, though the appearance of skin lesions of ''mahakushtha'' resemble leprosy. Etiological factors of ''kushtha'' are antagonistic food, toxins released from suppressed natural urges, and practices harmful to the blood and skin. It is ''tridoshaja'' disease, but because of variable proportion of one specific ''dosha'', causes variation in features and prognosis. Variable doshic impact on skin, gives different color, complexion, pain sensitivity, texture, deformities, discharge, and tactile perception. Generalized symptoms appear only in prodromal stage. | | All the types of ''kushtha'' are caused due to vitiation of ''tridosha'' with involvement of skin, blood, lymph and muscular issue.
