Ok, the consensus on the two proposed spells seems to be that Clot and Swell (the ReCo analogue of Bind Wound) is perhaps ok, but would have to be higher level; but Cleansing of the Festering Wounds (the ReCo recovery roll bonus) is pretty suspect. After thinking about it, I can see the point - to a point. 
Instead of aiming generally for "spells that does a body good", I should specifically focus on "spells that provide the effects of Medicine and/or Chirurgy". It is possible for Medicine to provide a bonus to disease recovery rolls, and for Chirurgy to provide a bonus to wound recovery rolls; as Fixer says, perhaps I should design these spells from the ground up (trying to emulate craft magic) rather than just translating them over from CrCo spells. (I had already planned on doing some of the chirurgical intervention procedures as literal ReCo craft magic spells.) I'll put out some more specific revised ideas in a new post.
A couple of reponses to JL's comments: I reviewed HoH:S and Covenants, and the pattern I see in the end is that Creo magic uses Int + Finesse, Rego magic uses Per + Finesse (possibly there are some exceptions). So that makes sense that these ReCo spells should be Per + Finesse - so noted for the future. Now, when you said "You're going to have to work from higher bases, and also invent these effects" - what did you mean by "invent these effects"? Something different from "inventing spells that cause these effects"?
