It is referenced by canon. Kabuto injected himself with blood of others, Jugo's included and got his powers. The Juinka was also stated to use Jugo's bodily fluids, so yes. Well, it certainly has natural energy inside and it's chakra too. When something has both chakra (physical and spiritual energies) and natural energy as well, isn't it senjutsu chakra?
