Wthin a few days the sores had dried, but the itch still means I scratch them ( not hard) in deep sleep, and they open up very quickly again.

The powders name she called "supan'', said as in Supan Buri. She said the supan was a type of tree. She pulverizes and dries its inner bark to a powder.

Old sanskrit defines 'Suphan' as gold. I can find no other reference to it except this colour. Its a very effective skin drying agent, and so cheap she gave me a pack.
