Quote from Lofty Wiseman's book. SAS Survival Handbook pg. 219
" Do not waste blood. It is rich in vitamins and minerals, including salt, that could otherwise be missing from the survivor's diet. Cattle blood is an important part of the diet of many African herdsmen. Cannibals who drank their enemies' blood found vision and general health improved and giddy spells, induced by vitamin deficiency, cured: the blood provided the missing vitamins and minerals."
Pg 298 of same book:
"Leave in the container in which it is collected but keep it covered. A clear liquid comes to the top. When separation seems complete drain it off. Dry the residue by the fire to form a firm cake. Use it to enrich soups and stews." :eek:
Hmm, as an aside, have you ever eaten prime rib or a medium to rare steak? lots of blood in that.
