The Dragon Blood Tree in Socotra

Trees in Socotra are known for their red sap, which has been used to make nail polish and medicines. The dragon's blood tree only exists there now but pollen of it has been found all around the Mediterranean as an fossilized or archaeologist have found pollen of it around the men. If we're not careful, it's going to be an extinct species of tree. But then that's good use for other things.
