[Avodah] Prohibition of Eating Blood

[Richard Wolberg]

It is interesting to note that with modern forensic medicine we have  
found that once the slightest amount of blood is left on any object,  
there is no way of removing every trace of it. There is a substance  
called luminol. Luminol is a versatile chemical that exhibits  
chemiluminescence, with a striking blue glow, when mixed with an  
appropriate oxidizing agent. It is a white to slightly yellow  
crystalline solid that is soluble in water and most polar organic  
solvents.
Luminol is used by forensic investigators to detect trace amounts of  
blood left at crime scenes. It is also used by biologists in cellular  
assays (tests) for the detection of copper, iron, and cyanides. There  
is no way in eliminating every trace of blood once it has appeared.
It would seem to me that perhaps the prohibition of blood centers  
around the fact that the tamei it conveys can never be fully eliminated.
I see a parallel between the paradox of the ashes of the para aduma  
and blood. As the ashes can render someone tahor who is tamei, and  
someone tamei who is tahor, likewise, without blood already inside of  
you, you would die. And conversely taking blood from the outside in,  
will cause a spiritual death.
