On the tiny TV channel in Nassau, the Bahamas, they even had a bush medicine woman showing the local herbs she had located, and how to use them.
I remember one lightly fragrant leaf to crumple in the bath for envigorating refreshment.
A Jamaican woman friend found some for me on a walk. It was delightful.
We also tasted tree fruits, like tree-ripened mango, and bought local coconut milk, avocadoes, conch, and papaya. You ever seen a fifteen-pound papaya? (Maybe it was only five, but big. ...It took a lot of lemons to eat it with.)
There are local experts everywhere!
Ask aboriginals, there's always a 'specialist' among them.
