Palo santo literally means "holy wood" in Spanish and it's traditionally burned as a ceremonial incense, similar to how bundles of white sage are used to "smudge" a room or area. Unlike sage, however, palo santo has a much brighter, more floral sent, and burns much cleaner. It's one of my scents of choice for the office and home.
One stick can be lit several times and will last weeks or even months, depending on how frequently you use it. Each bundle contains 3 ethically harvested palo santo sticks.
