Here's a real oddball solution for you, that might seem a bit deus-ex-machina, but nobody's mentioned it. IMC, I have mid and high level clerics regularly running public ritual ceremonies in town and village squares where they cast spells like Healing Circle and suchlike. In the larger ones, the high lvl Cleric's acolyte followers circle around the crowds buffing up with additional healing spells too.
FWIW, in one region, with the Nordic pantheon, they often do this at the conclusion several days of tournaments and battle games, so it sort of mimics the warriors fighting (you know as in up in Valhalla with Odin, Thor and the other Good Old Boys), and then being healed afterwards. And, yes, this ceremony is followed by a giant mead and ale drinking binge, replete with feasting. Hangover cures are not, however, dispersed by said Clerics.
