Review on the disease Kustha and its management in Ayurvedic literature

Abstract

Skin is a shield which protects us from various external invasions. Skin is the organ of the body which is readily available for inspection by the eyes. Of all the organs, skin is larger one and is exposed to disease and injury. Because of its visibility, skin reflects once emotions and it is the index of normal physiology. It is a link between internal and external environment and is also the seat of complexion which maintains beauty and personality. It creates an individual identity in the society. Changes in skin colour may be due to homeostatic imbalances in the body. Many inter related factors affect health of the skin, including nutrition, hygiene, circulation, age, immunity, genetic traits, psychological state and drugs. In Ayurveda, the word ‘Twacha’ or ‘Charma’ is used for skin. Twacha is derived from the Dhatu- Twach Samvarne meaning covering of the body. All the skin diseases in Ayurveda have been discussed under the broad headings of Kushta. Twacha is the seat of Sparshajnanendriya, which is one among seats of Vata and it is very extensive among all five Jnanendriyas.
