I should tell my friend that. She's having problems with dry skin, but on her scalp.
India is the world's biggest consumer of butter because they love ghee, which is clarified butter (the water and milk solids have been removed).
Of course it's always possible that your skin condition just spontaneously healed and it wasn't due to the ghee. I had one where I had these large round slightly red spots on my arms. The dermatologist gave me some cortisone cream which did nothing so I stopped using it. It went away by itself after several months. The worst part was when they did a "punch biopsy" where they took out a hunk of my skin about the size of a pencil eraser. And of course the pathologist didn't find anything, which the dermatologist warned me would happen because my insurance wouldn't pay for a derm pathologist, only a general one, and I was too cheap to pay for a derm pathologist.
