Blue Sage is known as "Grandma Sage". Blue Sage is also called Gray Sage or Rocky Mountain Sage, but the color is light gray-blue and the aroma is reminiscent of a mountain air with a light fresh scent. It is a bit sweeter and smoother than the White Sage, but for some people it can have a very pungent smell. Sage (Salvia apiana) is traditionally used to transform negative energies, cleanse people or cleanse places. Sage smoke neutralizes positive ions in our auras and spaces. Use it to cleanse, purify and protect people and places. Blue sage is also very earthy.
