I read somewhere that arrows can be removed by studying the wound and then inserting sticks of wood into the wound either side of the arrow shaft to locate onto the barbs and pulling the whole assembly out. I think this would only work with arrows designed for long distance or very accurate flight that have a simple head with the standard two barbs. Arrows shot at short range and for ambush as in the forests and jungles of Africa and other countries often have many barbs not just on the head but also on the shaft making the above mention process of removal impossible. Some people are just not very nice
