    Pawnee medicine men pulverized the corm to treat headaches and rheumatism.  The Cherokee used it to cure headaches, the common cold, ringworm, boils and “for scald head (and) scrofulous sores.”  Iroquois remedied adolescent diarrhea and listless infants with Jack-in-the-pulpit.  Also “for nonconception caused by cold blood” and for “temporary sterility.”  Chopped root mixed with whiskey cured colds.  It induced pregnancy for female horses.   Menominee pulverized the root, placed in incised lip to counteract witchery on the face.  The seed predicted death or recovery for the Meskwaki who also used it as poison to kill enemies.  The Potawatomi discovered that cooking the root for 3 days eliminated the poison.   HoChunk spread a compound of the root on neuralgia or rheumatism. Native Americans boiled the berries and roasted the root, for food. Garden cultivation since 1664.
