Dear Dominik,

Thank you for confirming what I thought to be the case - in Skt. It can refer to a range of skin ailments, including probably forms of eczema characterised in part by peculiar responses to heat. 

all best,
Matthew

Dear Matthew, no, "kuṣṭha" is Hindi for "leprosy".  But in Sanskrit Ayurvedic literature it refers to a range of skin conditions that may include what we today call leprosy but also vitiligo and other conditions causing skin pallor.  Other terms in this semantic field include "śvitra" and "kilāsa."
