History and Habitat.—Boneset is a common plant, indigenous to North 
America, where it ranges from New Brunswick to Dakota in the North, to Florida 
and Louisiana in the South. It grows in marshy places on the borders of lakes, 
ponds, and streams, where it blossoms from July to September. 
There is probably no plant in American domestic practice that has more 
extensive or frequent use than this. The attic, or woodshed, of almost — 
country farm-house, has its bunches of the dried herb hanging tops downward 
the rafters during the whole year, ready for immediate use should some member 
(Caprifoliacez).
