Sorry, you're mistaken...
It withdraws all moisture from application site, the rationale is that it often leaves raw clotting product (thrombin, platelets, etc) at the bleed.
The heat comes from it's mechanism of action...The rapid removal of the moisture causes an "exothermic" reaction, thus producing heat...Many people are mistaken thinking that quick clot was designed to cauterize wounds...It's not..The heat is a side effect.
