It could be any number of things. But here are my ideas. 1. It controls blood, reduces Zaraki's blood/clots it, to prevent him dying, I see that as a passive ability, he rarely bleeds out from excessive wounds) 2. A one shot kill attack contradicting his love of prolonged fights. 3. It's similar to "Susanoo" from Naruto. 4. Its ironically a kido type.

I think his Zanpakuto is named "Eliminate from Heaven".
