Sanzo is used to magical healing, the only thing weird about these potions is that they're... well, potions. Healing doesn't come in a bottle on the Sanzos' world, which is a shame because it would be terribly handy if it did. Hakkai's chi can't keep up with everything all the time.

"Oh! Of course," Koumyou pulls another potion out for Devero and hands it over, and goes about checking him over too. Because he can fuss over both of his favorite people.

"They're here," Sanzo tells the civilian, "and there, over there, and... here," he picks a piece of meat out of his golden hair, dropping it in disgust. "But they're not a threat, now."

Even if more came, his master didn't even let any from this batch escape. Sanzo is pretty confident another round would meet the same fate.
