Phoroz was a clear liquid extracted from the pollen of the phoroz lily, native to temperate tallgrass plains and steppes. Phoroz was prepared by steeping the pollen in vinegar for 7-10 days, straining the extract, then allowing the extract to evaporate to half its former volume.Phoroz caused slow paralysis (1-10 hours) and death (1-4 days); at minimum, it numbed the limbs ( for 1-10 hours).
