I've recently thrown together a modpack for myself, this mod included. However, while deep in the mines on a new world I noticed that I started healing whenever I ate something (natural healing, was eating cave roots courtesy of quark). That's despite the fact I have this mod in and enabled (currently got a couple plasters and bandages in my inventory).

I'm assuming this is probably either a bug in this mod on its own, or a compatibility issue. I'm currently playing on hard mode, and there is no error in the console being detected. The modpack I threw together is rather large, but I shouldn't (or at least I don't think) I have anything conflicting with this mod in particular (effecting natural health).

Edit: I'm using the latest version, 2.2.2 for 1.16.5
Edit2: I also have health canisters (though I don't think that affects natural regen)

AH crap that's on my side! Will make sure to fix this as soon as possible

Sorry for the wait. This should be fixed in update 2.2.3!
