Densmore distinguished two kinds of healing. The members of the Midewiwin heal with herbs and songs. Besides them there are the jaasakiid, seers who speak with the spirits in a shaking tent. Someone can be both, but they are different callings.
The Midewiwin has degrees: four, and more in some regions. At the first degree a new member learns in the woods the names and uses of a few simple herbs, which he carries in his medicine bag. In the higher degrees he learns the properties of rare herbs. A sick person can be taken into the Midewiwin in order to be healed. The old woman Mi'jakiya'cig ('clear sky') told Densmore that she was very ill as a young woman. Her parents gave a feast, a Mide man smoked the tobacco her father had brought and asked the spirits to prolong her life. There was singing and dancing, and she recovered.
Main'gans showed Densmore how he made bi'jikiwuk. The main ingredient was the root of Seneca snakeroot. With it came, in equal parts, the roots of fringed sage, ground plum and prairie rose. In a pail with about a litre of hot water he laid a little spoonful of the mixture at the east, south, west and north sides, and divided a scant spoonful of the snakeroot over them. The medicine was taken four times a day, a little at first and then more, up to a birch-bark measure of about a tablespoon. He also took a little spoonful of the dry powder, without water. Bi'jikiwuk was taken as a stimulant and for fits, and used externally to stop bleeding from wounds. Warriors carried it on the warpath.
Mi'nisino'wuck, the 'island herb', came originally from an island in Lake Superior and also stops bleeding. According to Na'waji'bigo'kwe it arose in the dream of a man who saw a thunderbird.
