Some of these old traditional remedies are now ingredients for branded medicines and fashionable health supplements. Look at tumeric and st johns wort.
One time back in the 1960s I had the gippy tummy staying with some people in Morocco in a remote village in the Atlas mountains and no where near a modern pharmacy. One of the ladies concocted a brew which tasted truly evil but next day I was fine. No doubt some ancient Berber remedy.
