Draught of Peace

The Draught of Peace was a potion which relieved anxiety and agitation. Its ingredients were powdered moonstone, syrup of hellebore, powdered procupine quills, and powdered unicorn horn. It should be a turquoise blue colour when finished, and simmered before being consumed.

Concoction
It was ironically a difficult potion to make, requiring that the brewer followed the directions carefully, because making a mistake could have drastic consequences. Adding too much of the ingredients, for instance, would put the drinker of the potion into a deep — and possibly irreversible — sleep.

The directions for making the potion were very detailed. Ingredients had to be added in the exact order and amounts specified, and the potion needed to be stirred seven times, both clockwise and counter-clockwise. Before the addition of the final ingredient, hellebore, the temperature of the flames had to be lowered, and the potion allowed to simmer for seven minutes.

If brewed correctly, the potion would emit a silvery vapour, but the possible characteristics of a failed batch seemed to be endless (everything from green sparks, dark grey steam, a sulphurous odour, a cement-like consistency, to a dangerous instability that would cause it to explode and set one's robes alight)
