"Smudging," as a word, is English in origin. It comes from the settler word "smudge," meaning a blurry mark or a smoky fire. The Anishinaabe-led Seven Generations Education Institute and The Canadian Encyclopedia both note this directly.[2,3] (see footnote: Seven Generations Education Institute; The Canadian Encyclopedia, Smudging) The term has been used as an umbrella for ceremonies belonging to many distinct Indigenous nations, although, as Seven Generations puts it, not all Indigenous peoples refer to the act as smudging.[2] (see footnote: Seven Generations Education Institute)
Among the most widely documented are the teachings of the Four Sacred Medicines, tobacco, cedar, sage, and sweetgrass, carried by the Anishinaabe (Ojibwe) and Cree peoples of the Great Lakes and the boreal north.[6,2] (see footnote: Encyclopedia Britannica, Four Sacred Medicines; Seven Generations Education Institute) Each medicine has its own name in Anishinaabemowin: asemaa, giizhik, mashkodewashk, wiingashk. Each has its own protocol. The Cree term for the ceremony is atisamânihk, meaning "at the smudge." The Ojibwe term is nookwezhigewin.[3] (see footnote: The Canadian Encyclopedia, Smudging) These are not synonyms for an English category. They are specific ceremonies with specific names.
White sage ceremony, the practice most often pictured when outsiders imagine "smudging," belongs specifically to the Indigenous peoples of Southern California and northwestern Mexico, the only place on earth where Salvia apiana grows wild.[4,5] (see footnote: California Native Plant Society, White Sage program; United Plant Savers, Salvia apiana profile) The Tongva, Chumash, Cahuilla, Acjachemen, and Ohlone nations have stewarded this plant and the ceremonies around it for generations.[7] (see footnote: Bean & Saubel, Temalpakh (1972))
The Lakota, often assumed to be the source of smudging in general, have their own sacred smoke practice: the Čhaŋnúŋpa, the sacred pipe ceremony, one of the Seven Sacred Rites given by White Buffalo Calf Woman. It uses čaŋśaśa, red willow bark, and is distinct in form, plant, and meaning from what is colloquially called smudging. Treating Lakota ceremony and Anishinaabe ceremony and Tongva ceremony as one generic ritual is itself a small act of erasure.
