Interesting website which lists with photos many of the common plants in Belize that are used for bush medicine.
"...Before modern medicine developed laboratory drugs, our ancestors all over the world used herbs and weeds for health. In many parts of the world today, they are the only treatment available and sometimes work better than manufactured drugs. Many plants exhibit the "Doctrine of Signatures" which is a concept that there is some physical characteristic about a plant that signals what it could be used for on the physical body.
One great example of this concept is the red peeling bark of the Gumbo-Limbo tree. Also called the "Sunburned Tourist Tree" parts of this tree are used to effectively treat poison wood exposure, sunburn, insect bites and most any other skin related problem..."
