Everyone who watches wrestling knows that the blood in pro wrestling matches is real. In most cases the wrestlers cut themselves to produce that effect.

But there are many who still believe that it's done with blood capsules like in movies or even (chuckle) ketchup packets.

Could blood capsules and ketchup packets actually produce the same result as the real thing during extended physical activity?

Something very similar happened in the Heinken Rugby Union competion here in Europe .

A player from one team Harlequins, was playing against the champions from Ireland Leinster, and he fake an injury intially using a Blood capsule so that he could come off and be substituted. Later the team doctor used a Scapel to cut him to create a real injury that needed stiches.

WOOOOOOOO!!!!!! A PRO-WRESTLING MYTH!!!!!!!!!!! I'm WATCHING WRESTLING RIGHT NOW!!!!!!! ITS AWESOME!!!!!!!

I always loved when they said it was ketchup. As if ketchup looks anything like blood and even if it did, the putrid smell of it would give it away.

I think they only need the blood capsules if they're bleeding through the mouth and only if it's a planned one. (Like when they're doing some kind of internal injury thing.) Mick Foley said that if you get a cut lip or something by fluke, you just mix it with your saliva and you can get an enormous amount of 'blood'
