In Ayurveda all the skin diseases have been described under the umbrella of Kushtha. The word Kushtha denotes all types of skin diseases – Tvacha Vikara. Due to causative factors, the 3 doshas namely Vata ,Pitta ,Kapha get vitiated and in turn contaminate with the dushyas like tvak, mamsa, shonita, and lasika causing kushtha or skin disorders of various forms and presentations.Kushtha vyadhi thus formed manifest in the form of 7 types of Maha Kushtha and 11 types of Kshudra Kushtha. In all types of Kushtha; Saptako Dushyasamgraha is of great importance.None of the Kshtha manifests due to vitiation of any one dosha. By understanding Kushtha Vishesha and gunas of predominant dosha Hetu of Kushtha can be guessed. Knowing mutual relationship of Hetu–Dosha – Kushtha plays key role in diagnosis of any Kushtha. It further helps in treatment and management of Kushtha.
