=== Introduction ===
Skin is the largest organ of the body constituting the integumentary system, comprising of skin, hair and nails etc. It constitutes 16% of body weight. Skin has the total surface area varying 1.2-2.2 m2. It is a combined product of ectoderm as well as of mesoderm. Kushtha [skin disorder or dermatosis] is a chronic disease which presents with ugly colors / complexion/ texture and altered tactile perceptions of the skin. The word “kushtha” is derived from “kushnati vapuh” meaning that which alters complexion of body by extracting.
Skin is the largest organ of the body constituting the integumentary system, comprising of skin, hair and nails etc. It constitutes 16% of body weight. Skin has the total surface area varying 1.2-2.2 sq.m. It is a combined product of ectoderm as well as of mesoderm. ''Kushtha'' (skin disorder or dermatosis) is a chronic disease which presents with ugly colors / complexion/ texture and altered tactile perceptions of the skin. The word ''kushtha'' is derived from ''kushnati vapuh'' meaning that which alters complexion of body by extracting.
Second aspect is that it is a sensory organ too, and is seat of vata dosha. In case of kushtha vitiated vata in skin manifests as, horripilations, numbness, and loss of tactile perceptions.
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.
Third aspect, skin is the sub-tissue or upadhatu of mansadhatu, texture of skin depends upon muscle texture, so the dermal deformities spread upto the mansa dhatu or musculature and skin texture causing ugly shape of skin lesions. Lastly, affliction of deeper layers of skin deteriorates the ulcer healing ability of skin and damages the defense mechanisms against enormous pathological invasions. Thus, the kushtha stands for long time with more and more uglier shape.
This chapter is placed after “Prameha chikitsa”, because one of the complications of prameha is carbuncle, which penetrates deeper into the muscles and is very similar to kushtha but the etio-pathogenesis is very different. Indulging in heavy to digest food products is responsible for increase of kleda [excess moisture] in the body. Such kleda is carried by mutra and leads to increase in quantity and frequency of mutra leading to pathogenesis of prameha. When same kleda spreads throughout the body causes shaithilyata (looseness of body tissue) and also vitiates meda dhatu. Vitiated kleda and meda are responsible for mansa dusti which is responsible for pidika genesis and manifest as change in colour, texture and sensation of tvacha (skin). This leads to various skin diseases.
In the context of ''kushtha'', four aspects of skin are important. First is that it consists of six layers (as described in [[Sharira Sthana]] chapter 4), and each layer is seat of specific type of gradually progressing ''kushtha''.
Another disease named visarpa is explained later in 21st chapter of this section also has these components commonly, but due to prominence of impurity in blood that is a rapidly spreading disease whereas kushtha is slow progressing disease. Whereas visarpa advances into the visceral parts, kushtha spreads horizontally and limited to skin only.
All the kushtha are curable except mahakushtha named “kakanak”, because it does not have any systemic involvements. At the end of the chapter, three types of skin disorders caused by hypo pigmentations are mentioned as “shwitra” with their treatments.
Second aspect is that it is a sensory organ too, and is seat of ''vata dosha''. In case of ''kushtha'' vitiated ''vata'' in skin manifests as, horripilations, numbness, and loss of tactile perceptions.
