After receiving the energy herbs from Dragon God, Raphael immediately prioritized feeding Michael first. With his current injury, if it wasn't dealt with soon, this unlucky genie was about to 'go to heaven'.
He stuffed the whole energy herb into Michael's mouth and then had no idea how to make him chew it. He couldn't just punch him in the mouth to 'help' him chew either. And chewing it himself then feeding it to him wasn't possible because if he did that, the energy herb would get completely absorbed by Raphael's own body.
"If you don't chew, then you die, and that's on you. Don't blame me."
Of course Michael didn't hear a damn thing, but the system did. So the kind-hearted system sent an electric current through his body to wake Michael up. Then he chewed once and passed out again.
The massive energy from the energy herb flowed into his body, combined with his god-level talent, and made his body recover quickly.
