[Lord Nikon]

However reading the quotes above it is evident that the intention is to refer to the consumption of blood, since Acts encapsulates it within the context of foods, Genesis within the context of an accounting for unnecessary bloodshed. Neither refer to the use of blood to heal. Even within the bible there is reference to using parts of one body in another, Eve was created from the rib of Adam.
I fail to see the prohibition of blood freely given that another may live as anything other than an extension of the Good Samaritan giving of himself to aid someone in need.
