Stops the bleeding.
I've had a coronary artery bypass to 4  of my coronary arteries and 2 years later had to have a coronary stent put in.  Now I'm on Eliquis and Plavix, anticoagulants (blood thinners). Any little cut just bleeds quite a bit, but these sticks stop the bleeding of small cuts quickly and cleanly.  It stings a bit and colors the spot black, but they get the job done. As new skin grows, the black stain will drop off. Silver nitrate does that.
