Giorno quickly threw in, "I can heal any wounds you have too, padre."
"Don't believe him!" Mista pointed at Giorno, "He healed my bullet hole wounds one time and it was more painful than actually being shot!"
"I told you my Stand's ability isn't exactly healing, it's regenerating living material. It was your own fault for not listening to me."
In the absence of suitable replacement parts from the same species, though, gremlins attempt to fix living beings using parts from any other living creature—or from machines. These "repairs" do not turn people into cyborgs. Such ministrations are a death sentence, because the gremlin cannot fix a person using car parts. Thus, the person still appears "broken" to a gremlin, which means that the gremlin cannot leave the person alone, and attempts more repairs... until eventually, the person dies from shock or blood loss, and the gremlin sadly dismembers its "project," keeping the best parts in its lair.
The strongest biological healing agent... is a mushroom. Found in an abandoned house. I find some humor in that [...] Can be either ground into a paste or... planted directly into the wound. A small warning: you'll feel it enter you, and it is every bit as unpleasant as it sounds.

Jaune: Treatment? I thought I was able to heal myself during the battle?
Professor Peach: I don't know what I would call whatever it is you did yourself, Mr. Arc, but I would not call it healing. [sighs] When you were brought in the first thing you required was an emergency blood transfusion, which was easy enough to do. The wounds on your abdomen however, were extensive to say the least.
[Peach shows Jaune his MRI scans]
Peach: Yes, your wounds stopped bleeding, saving you from dying of shock, but it came with a series of other complications. Instead of accelerating the normal healing process as Aura normally does, your Aura instead regenerated your flesh in the most efficient way to reattach muscles and stop bleeding.
Jaune: And I'm guessing that's a bad thing?
Peach: [nods] The regeneration ignored the way your organs were supposed to heal. So to prevent you from living in constant pain with no appendix and only half of your intestines, we had to do emergency surgery.
Jaune: Surgery?
Peach: Indeed. While you were unconscious, I had to manually reopen and stitch together the majority of your wounds.
