The Draught of Peace is a potion which relieves anxiety and agitation. Its ingredients are powdered moonstone, syrup of hellebore, powdered porcupine quills, Valerian root, and powdered unicorn horn. It should be a turquoise blue when finished and simmered before being drunk.
It is ironically a difficult potion to make, requiring that the brewer follow the directions carefully, because making a mistake can have drastic consequences. Adding too much of the ingredients, for instance, will put the drinker of the potion into a deep - and possibly irreversible - sleep.
