Trees With Sap That Looks Like Blood
It may sound like something out of a horror novel, but Dragon's Blood Trees are very real. These trees can be found on the island of Socotra in Yemen. They may appear ordinary from the outside, but Dragon's Blood Trees contains red resin known as "emzoloh" that looks just like blood. Emzoloh, or cinnabar, is known to the Socotris for having a range of medicinal uses.
