Cauterize – Fire to heal wounds? 😮

Question

In a scene from The Blacklist, one of the characters uses a lighter on a wound to “cauterize” it. It looks painful but works. What exactly is it and is it actually done in medical scenarios?

Answer 1

It’s used to stop bleeding in an emergency by closing the wound. It doesn’t heal you, it just stops bleeding. It’s used if you’re losing a lot of blood so you don’t bleed out.
