Cedar is first and foremost a medicine of protection. It is often used to cleanse a home when first moving in, inviting unwanted spirits to leave and protecting a person, place or object from unwanted influences. Cedar is often used in the sweat lodge ceremony. A few pinches are thrown on the red-hot rocks, immediately sparking into a yellow glow and releasing their aroma. The smoke of burning cedar is said to attract the good spirits and eliminate negative energies.
