Boneset, also known as American boneset, is a North American clumping shrub in the daisy family found in damp woodlands, marshes and roadside ditches, or wherever there is water nearby. Its species name reflects the growth habit of the stem that makes it seem to perforate the base of the leaf. Early herbalists took this as a sign that the plant could serve as bandaging to set broken bones, hence the common name bone-set. However, some etymologists believe that the name comes from the fact that 18th century doctors used the plant to treat a form of mosquito-borne virus called breakbone fever, also known as dengue virus. This use led to the additional common names sweating-plant, agueweed and feverwort, as well as the modern study of the plant’s antimicrobial, anti-inflammatory and antioxidative activities.
