Blue sage, also known as "Grandmother Sage" or "Azure Sage," is a distinct variety of sage used for smudging rituals. What sets it apart from other sages is its vibrant blue-gray color and milder, sweeter aroma. Blue sage is valued for its cleansing properties, as it is used to purify spaces, ward off negative energy, and promote peace and relaxation when used in smudging ceremonies, making it an excellent choice for clearing and harmonizing your home environment.
