dyaditya Ras is a classical Ayurvedic herbo-mineral formulation traditionally used in Ayurvedic practice for skin disorders, particularly conditions involving hypopigmentation and white patches. The Unjha label describes its traditional use for leucoderma, hypopigmentation and other skin disorders. Classical references also describe Udyaditya Ras as a formulation used for Kushtha (Ayurvedic category of skin disorders).
