i think the reason for the out pouring of blood in the ancient times, was something to with the sacredness of it. it was instructed by the hewbrew God, not to eat it, but to pour it onto the ground before the consumption of the animal. {we are talking about what is known as lifes blood} what runs through the artaries, not the plasma surrounding the inside of the flesh. and i would suppose some beliefs have taking things out of contents etc. i dont know about the pagan/wicca side though. i would like to know though, if you have the answer? thanks.
