Allthough all plants are purposeful and important, four plants are held the most sacred:

1. Tobacco: Used in the offering of prayers to the Great Spirit. The smoke that holds the prayers are lifted skyward.

2. Cedar: Purifies the body and spirit; good fortune comes your way when carried upon ones self.

3. Sage: Cleans the body and spirit. It repels all negative energies.

4. Sweetgrass: Purifies like cedar and brings in positive energies.

The knowledge and values of these four plants have been handed down from generation to generation. Storytellers taught the traditions and history of these plants to keep them alive for their tribes.

One thing for everyone to be aware of is that they should ask permission before touching or moving these plants if they are found in a patient room or belongings.
