Nutmeg
One of the more unpleasant cold symptoms is that achy, restless feeling that makes it difficult to sleep, even though you feel exhausted. When that happens, head to your spice stash and pull out the nutmeg. Nutmeg contains tryptophan, the same stuff that makes us pass out after a heavy turkey meal on Thanksgiving. Nutmeg is amazing for sleep. Grate nutmeg on your food or into your tea—it’ll knock you right out, says Sietos.
