In this site that many of you already know, Dr. Muramoto talk something interesting about blood fractions and the way that Watchtower choose ones and discard others.
At some point he says:
"Here, I will summarize the purpose of each component therapy.
- Red blood cells = to restore oxygen delivery to the peripheral tissue
- White blood cells = to treat infection by restoring deficient white cells
- Platelets = to restore platelet function for uncontrollable hemorrhage
- Plasma = to restore the blood coagulability by adding coagulating factors
Of course there are many other purposes for component therapy, but those are the main purposes in current practice, which anybody can read in elementary medical textbooks. There is no role of "nourishing" or "feeding" in those "major" components. Ironically, there is one blood component which is occasionally used to correct malnutrition. That is albumin which is permitted to use according to the Watchtower Society. Hypoalbuminemia occurs in people with poor nutrition. Administering albumin is one of the quickest ways to correct this problem. It quickly increases serum albumin level, which is one of the indicators of malnutrition, and alleviate the symptoms of malnutrition. If Furuli and the Watchtower Society truly believes "nourishing" with blood products is prohibited by the Bible, albumin should be refused, not red cells or platelets".
Its a interesting fact about albumin that I really never read in Watchtower's articles on blood. I wonder why?
