Physician's Touch
You can administer even greater cures with a touch, and if you feel it's necessary, you can use your knowledge to cause harm.
When you use Hand of Healing on a creature, you can also end one disease or one of the following conditions affecting the creature: blinded, deafened, paralyzed, poisoned, or stunned.
When you use Hand of Harm on a creature, you can subject that creature to the poisoned condition until the end of your next turn.
