Protection From Poison Scroll

The text on this worn-down scroll appears unintelligible, but they seem to be for some sort of spell.
You touch a creature. If it is poisoned, you neutralize the poison. If more than one poison afflicts the target, you neutralize one poison that
you know is present, or you neutralize one at
random. For the duration, the target has
advantage on saving throws against being
poisoned, and it has resistance to poison damage.
