There is no single Indigenous medicine, but many peoples share the idea that health is balance between body, mind, community and nature. The English word medicine often has a broader meaning in Indigenous traditions: it is also about spiritual power and protection.
Among many peoples, such as the Anishinaabe and the peoples of the Prairies, there are four sacred medicines: tobacco, sage, sweetgrass and cedar. They are burned to cleanse, to pray and to protect.
The sweat lodge is, for many peoples, a ceremony of purification and prayer. The medicine wheel, with its four directions, is an important symbol for some peoples too, but not for all.
