Orochimaru's chakra..... this is proven when Kabuto gets Orochimaru's Senjutsu chakra out of Anko's Curse Mark and later Orochimaru absorbs it back from Kabuto.

My point is, the arguing is pointless, because there is nothing to argue about. Chakra + natural energy = Senjutsu chakra. User of Senjutsu = Sage.
