As mentioned in the changelog, there are now unguents for treating frostbite, infection, and fractures. They're currently available to on-duty physickers in infirmaries, and will later be craftable.
Note that in the future, more significant infections and fractures may require additional steps to treat successfully. It'll take more than just slathering some unguent on a broken bone to fix it. Particularly nasty infections may have to be surgically removed. But for the time being, unguents do the trick to keep all these wounds healable.
