Maybe, but i don't think the best soap the world has ever seen will keep me from smelling like sweat after a few hot days
Need me to mail some for you?
It’s trivially easy to find ancient soap recipes and revert them at hope. Or one can buy Aleppo soap, or Castilian soap from specialty markets.
It’s not like there’s some lost secret, or extinct ingredients - it’s soap, and it’s been a pretty simple thing to make for thousands of years.
