Snake Oil
This is a story told to me Majid (see http://kahina-givingbeauty.com/blog/light-of-the-prophet/). An elderly great aunt of his, living in the remote countryside North of Fez, was bitten on the wrist by a poisonous snake while working in her garden. Unable to reach a hospital she drank an entire liter of 40 year old argan oil. She lived another 20 years.
