Undo Harm ed5.5

You reverse time around a fresh wound, healing some of the damage. A creature you touch regains up to 1d4 hit points, but no higher than the amount of damage that they took since  their last turn. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the healing increases by 1d4 for each slot level above 1st.
