Bone wax is mae of beeswax containing a softening agent such as paraffin. Bone wax is used to mechanically stop bone bleeding during surgical procedures. The bone wax is smeared across the bleeding edge of the bone, blocking the holes and causing immediate bone hemostasis through a tamponade effect. Bone wax is supplied in sterile sticks, and most often requires softening before it can be applied. Once applied, it essentially never goes away. Although inexpensive, easy to use and immediate, bone wax has a number of adverse reactions associated with it.
