No need for time travel here... I currently live in the south of Morocco and this is exactly the kind of advice I am given here constantly. My SO went through months of dietary restrictions based on such advice; got her to hospital 2 weeks ago and today the lab results are in: bacterial infection. We are looking forward to the first proper dinner in a very long time. My personal highlight on local advice I was given: "Keeping a tortoise in your house helps with asthma. My cousin has asthma and when it is really bad, he comes back to his parents' house and after a few days it is much better!" (That house is in a very small mountain village with very clean air, he lives in a very big city full of cars and he does not dare to smoke anywhere in his home village or his parents' house lest his parents see that.. go figure.)
