Some tea with honey. Sips from a glass of flat soda, preferably not caramel-colored. A cold shower followed by no bath. Form a tent of a towel and slip your head underneath. Alternately expose head to steam and splashes of cool water.
Folk remedies are like a certain cardboard box.
This box is big enough to contain him and her and a few significant possessions, providing they are chosen quickly and mindfully. In the box the fever swirls all around them. As the fever passes her it fills up her chest. She thinks this feels like something she knows and compares it to unspun cotton. Soon enough this cycle leads to bankruptcy.
