Samprapti of Kushta shows tridosha dushti (Vata and Kapha pradhana) and dushya are twak, lasika, shonita and mamsa predominantly, so the line of the treatment should be ushna, tik shna, Vata Kapha Shamaka, Rakta Prasadana mainly. A literary review of the rasa panchaka is done to assess their probable mode of action. The literary screening c oncluded that there are about 98 dravya ( Herbal and Metal) are recommended as Kushtaghna, but their specific action is not defined on the basis of their Rasapanchaka.

Kushta is a chr onic disease that has substantial psychological and social impact on a patient’s life.
