2. Don’t Touch the Manchineel Fruit
Those big shady trees with the little green apples look inviting and harmless enough, but manchineels are toxic. You don’t want to touch any fruit on the ground, or even sit under the boughs during a rain shower. These trees contain a milky sap that can blister the skin on contact and cause blindness if rubbed in the eye. In fact, the Caribs used to use this on their poison arrows. Many manchineel trees on Barbados beaches have a warning sign on them or are painted with a red ring, but not all.
