Eupatorium perfoliatum, commonly known as boneset, is a perennial herb native to North America. It typically grows in wetland areas and can reach heights of 2 to 4 feet. The plant features opposite leaves that are joined at the base, giving it a distinctive appearance. Its small, white flowers bloom in late summer and attract various pollinators. Historically, boneset was used in traditional medicine to treat fevers and flu-like symptoms. The plant contains compounds that may have anti-inflammatory and immune-boosting properties. However, it should be used with caution, as high doses can be toxic.
