Sweetgrass
Hierochloe odorata
Sweetgrass is one of the four sacred medicines of many Indigenous North American nations (along with tobacco, cedar, and sage). Medicinally, it contains coumarin, phytol, and flavonoids with antioxidant and anti-inflammatory properties. Research has shown anti-inflammatory activity comparable to aspirin, antimicrobial effects against several pathogens, and emerging evidence for neuroprotective coumarin derivatives. In Anishinaabe and Lakota traditions, sweetgrass is used both ceremonially and medicinally — for respiratory ailments, infections, and to support spiritual wellness during illness including cancer.
