As many players sayed, there are problem that there are too many little deep cuts for 2-4 hp that is too annoying to heal with poultrices, and too expensive with bandage.
So idea: Make possibility to cauterize the wound.
You will just make a firebrand, and use it in a wound. The would will become "burnt cut", that will wery slowly heal, like 1 per day.
And also there are limits:
Its depends on dexterity and survival. If parameters are low, the wound will become more hp, than it is.
It can't be used on deep cuts more than 4 hp.
