Sweetgrass (Hierochloe odorata, reclassified as Anthoxanthum nitens) is a fragrant perennial grass used for ceremonial cleansing across multiple Indigenous nations of North America, particularly among the Plains, Great Lakes, and Eastern Woodland peoples. Unlike sage’s sharp, antibacterial smoke, sweetgrass smoke is sweet, soft, and binding—it calls positive energy in rather than driving negative energy out.
What Is Sweetgrass and How Does It Differ from Other Cleansing Herbs?
Sweetgrass grows in river valleys, lake shores, and wet meadows from Alaska to the Atlantic coast, and across northern Eurasia where it is sometimes called holy grass or vanilla grass. The genus name Hierochloe means “holy grass” in Greek, a translation that predates European contact with American varieties. The plant itself was used for centuries by northern European peoples too, woven into church floors on saints’ days, but the ceremonial clarity tradition is Indigenous.
The distinction matters. White sage (Salvia apiana) produces a dense, astringent smoke that physically repels bacteria in the air. That is a clearing smoke: it removes. Sweetgrass smoke does not test well for the same antibacterial properties. Its purpose is not removal. It is invitation. The smoke is said to attract good spirits, ancestors, and positive energies. In many traditions, sweetgrass follows sage: sage clears the room, sweetgrass fills it with what you want to stay.
The plant’s chemical signature is coumarin, the same compound that gives fresh hay and woodruff their smell. When burned, coumarin produces a vanilla-like scent that clings to fabric and hair for hours. That persistence is part of the point. The sweetness stays.

Where Did the Sacred Use of Sweetgrass Come From?
The earliest documented reference to sweetgrass in North American ceremony comes from Jesuit missionary accounts of the Huron-Wendat in the 1630s. Jean de Brébeuf noted that the Huron burned a grass they called “la plante qui sent bon” during healing rituals. He could not have known that the practice was already older than the language he was trying to translate.
The Blackfoot Confederacy tells a longer story. Sweetgrass was given to the people by the spirit of the buffalo. The braids of the grass are worked into three-strand plaits that represent the unity of body, mind, and spirit, or the connection between the human, the natural, and the spirit worlds. Among the Ojibwe (Anishinaabe), sweetgrass is one of the four sacred medicines, alongside sage, cedar, and tobacco. Each medicine is a distinct gift. Tobacco carries the prayers. Sage cleanses. Cedar protects. Sweetgrass calls in the good.
The Haudenosaunee (Iroquois) use sweetgrass in their Thanksgiving Address, the opening words of every gathering that lists the gifts of the natural world in order. Sweetgrass is the first plant thanked. It is the grass whose roots bind the earth, whose scent lifts the mind toward gratitude.
There is no single origin date. The practice precedes all written records. What we can say with certainty is that by the time European botanists catalogued the plant in the 18th century, its ritual use was already a settled continental tradition, from the Cree in the subarctic to the Lenape along the Delaware River.
Sweetgrass symbolizes welcome. That is the simplest and most complete statement. The smoke is offered to guests, to elders, to people entering a lodge or a home for the first time. It says, without words: you are safe here, you are wanted here, and whatever you brought with you that does not belong may leave.
The three-strand braid carries the same meaning. Each strand is not separate. They are interwoven. In some teachings, the braid represents the three parts of a person: the physical, the mental, and the spiritual, which cannot function apart. In others, it is the winter months, the spring months, and the summer months, all bound into the turning year. In Cree tradition, the braid is a woman’s hair, and cutting it is a gesture of mourning or of giving.
The color is also symbolic. Sweetgrass is pale green, almost yellow when dry. It does not look dramatic. It looks like what it is: a humble grass growing at the edge of a stream. That humility is the point. The most powerful medicines often look like nothing special.

The braid is lit at one end until it glows, then the flame is blown out. The braid smolders, producing a steady ribbon of white smoke. The user fans the smoke over themselves or another person, starting at the head (the seat of thought and spirit) and moving downward.
The order matters. In many Plains traditions, you cup the smoke in your hands and draw it toward your face three times. Once for the eyes, so you may see clearly. Once for the ears, so you may hear the truth. Once for the mouth, so you may speak only what is good. Then you draw the smoke over your heart, and over the rest of your body.
Sweetgrass is also braided fresh, when the grass is still green and pliable. The braids are dried and stored in a dry, dark place. A single braid can last years if burned sparingly. The plant is never cut, only pulled, and the braiders often work in silence or while singing. The act of braiding is itself a meditation. It takes attention. You cannot braid sweetgrass and think about something else.
Some practitioners burn sweetgrass in a shell or a clay bowl, the same vessel used for sage. Others keep a separate bundle for sweetgrass alone. The two smokes do not mix well. Sage is aggressive. Sweetgrass is gentle. A room that smells of both at once can be confusing to the nose and, some say, to the spirits.
How Does Sweetgrass Compare to Other Cleansing Herbs?
White sage clears. Sweetgrass invites. That is the core difference, and it governs every practical choice.
A person who has just been through a difficult argument might use sage to clear the residual tension from the room. Then they would light sweetgrass to restore a sense of peace. A healer might smudge a patient with sage first, to remove illness, then with sweetgrass, to welcome the patient back into wellness.
Cedar is a protective smoke, used to block negative energy from entering a space. Sweetgrass does not block. It attracts. Think of it as a bell, not a wall. Cedar surrounds. Sweetgrass beckons.
Palo santo, which comes from South America and is used in similar ways, has a resinous, citrusy scent closer to pine. Its use has become popular outside its original Indigenous context, but sweetgrass remains the more culturally specific herb. It cannot be imported from elsewhere. It must be harvested where it grows, and the people who know how to harvest it properly are the ones who have always done so.

Commercial demand for sweetgrass has grown significantly since the 1990s, and not all harvesting is sustainable. The plant spreads by rhizomes, not seeds. A single patch can be hundreds of years old. Overharvesting by cutting the roots or pulling the entire plant kills the colony.
Ethical harvesters follow the same rule the woman in the Maine salt marsh follows: pull upward, leave the crown intact, take no more than one-third of the stalks in a patch, and never harvest from the same spot two years in a row.
If you cannot harvest your own, buy from Indigenous-owned suppliers who document their sourcing. Avoid mass-market sweetgrass from unknown origins. The plant is not difficult to grow yourself if you have wet soil and full sun, but it spreads aggressively and is considered invasive in some regions.
FAQ
Can you burn sweetgrass every day? Yes, but most practitioners use it sparingly due to its potency and the cultural significance of treating it as a sacred medicine rather than a daily air freshener.
Does sweetgrass have any scientific benefits? Unlike sage, sweetgrass has not been shown to have significant antibacterial properties. Its primary effects are aromatic and psychological—the coumarin scent has been documented to reduce stress and promote calmness in controlled studies.
Can non-Indigenous people use sweetgrass respectfully? Yes, if they learn from Indigenous teachers, source ethically, and use the plant with understanding of its cultural context rather than treating it as a generic “smudge stick.”
Sweetgrass is not a tool for removing what you do not want. It is a tool for welcoming what you do. That distinction changes everything about how you use it, how you think about it, and how you treat the people who have cared for it since long before any written record.
The woman who gathers sweetgrass in a Maine salt marsh does not cut the stalk. She pulls. She thanks the grass in her own language. That gesture is not sentimental. It is the oldest rule of harvesting something sacred: take only what you need, leave the rest alive, and never forget that the plant gave itself to you.
