Heals 5 points of damage and removes the Diseased condition. It does not restore HP lost due to Disease damage, but will stop continuous Disease-based damage that was in effect when the potion was consumed. It does not inoculate the drinker against further Disease.
Disease can deal HP damage (though not always), but if you fail a saving throw for Disease, under certain conditions, there may be repercussions. Simply taking Disease damage won’t trigger this condition.
