Although less known, sweetgrass is a purifying agent which can be used to smudge your house (cleaning with smoke). It is also a sacred plant within American Indian tribes and grows in the Rocky Mountains. Sweetgrass is also called 'the braids of mother earth'. Before harvesting, it is braided. She is dried and sold as a braid.
Sweetgrass has a natural sweet smell and reminds you of your natural origin. It makes people long for nature and is therefore often burned in combination with sacred wood (palo santo). It creates a positive mood.
