A Pacific Foment.
Take Vine and Willow leaves, Lettuce, each 2 handfuls; whitewater Lily flowers, red Roses, each 1 handful; white Poppy heads (with the seeds) 2 ounces; boil in Water 1 gallon to 2 quarts; in the strain'd dissolve Opium 2 drams.
Use it warm with a Sponge, to the Temples, Forehead, whole Head and the Feet. It deserves to be employ'd, where 'tis not altogether safe to give Hypnotics; namely in Fevers that rage Impetuously, with Fervour, and pulsing pain of the Head, pertinacious Watchings, and danger of a Delirium: For by its soft Cherishment, kindly Warmth and temperate Humidity, it humects, mitigates and appeases acrious, boiling Juices, and derives them from the Head, either by Perspiration or Circulation, and so disposeth the weary, worn-out Spirits to rest and procureth placid Sleep.
But in Fevers of a malignant Nature, where the Spirits, by the Venom being opprest, staggering, scarce able to sustain themselves in orderly rank and file, and almost struck Dead, are in danger of falling into Dozing or Convulsions: In this Case, I advise it to be avoided as Poison.
