Blue sage is the common name for several aromatic salvias, most often Salvia azurea of the central and eastern plains and Salvia clevelandii of Southern California and Baja. Bundles sold for smoke cleansing are usually the western kind, gathered from the same dry chaparral country that gives us white sage. It entered wider smoke-cleansing practice as a gentler companion to white sage, chosen when a household wants clearing without an overpowering room, and it is often reached for by people seeking a respectful alternative to a plant held sacred by Indigenous Californian peoples.

Blue sage refers chiefly to Salvia azurea and Salvia clevelandii, perennial shrubs in the mint family Lamiaceae, both named for the blue to lavender flower spikes they carry. Their fragrance comes from volatile leaf oils dominated by camphor and 1,8-cineole, with borneol and pinenes in supporting roles, a profile that reads lighter and cooler on the air than white sage.

Blue sage is known in folk tradition as Grandmother Sage, a name given for its nurturing, unhurried character compared with the sharper sages., It also carries the common name Mountain Sage, tied to the high open country where the aromatic salvias grow., and The wider sage family has been linked since antiquity to wisdom and long life, with leaves carried and burned as tokens of both.

Not every clearing needs to be a storm. I let soft smoke move through my rooms and my thoughts, carrying off what the day left behind, and I allow calm, protection, and quiet plenty to settle in its place.
