Boneset has traditionally been used internally as a tea (infusion from the dried herb), powdered herb, or in fluid extracts (from fresh most often)/tinctures/capsules.
*NOTE: Due to the presence of pyrrolizidine alkaloids, I can’t broadly recommend the internal use of this plant. Complications directly from boneset are rare, however the presence of these alkaloids have been associated with liver damage, liver cancer and veno-occlusive disease. For this reason, many herbalists recommend that this plant be used only in moderate doses and for short periods, with the guidance of a qualified healthcare practitioner, and only in patients with no underlying liver disease or compromised function.
Boneset can also be applied in a poultice, on swollen joints or inflamed areas.
Do not use if pregnant, nursing, or if you are suffering from any condition which may compromise the liver. Do not take internally in large doses, for prolonged periods (longer than two weeks) or without the guidance of a qualified healthcare practitioner.
Pyrrolizidine alkaloids (constituents present in boneset and certain other plants), have been linked to the onset of liver complications and even liver cancer, when these alkaloids are taken in high doses or for long periods of time. I personally wouldn’t suggest taking boneset internally without the advice of a qualified healthcare professional.
I suggest consulting a pharmacist or physician before starting any herbal supplement if you are taking a prescription medication or have serious underlying health concerns.
Boneset was one of the most extensively used medicinal herbs throughout North American history. It was valued highly by traditional First Nations healers. However, it was not as well-documented on other continents.
Apparently boneset got its name because of its use in treating dengue fever, and other painful musculoskeletal conditions.
It has a cold, dry constitution.
