Pleurisy weed is better known in parts of the country as butterfly weed. The plant is a variety of milkweed native to eastern North America. It's a popular plant in country gardens, and is known to attract butterflies, particularly monarchs. It has been used medicinally by a number of Native American tribes for centuries. Much of the plant is edible, including the young shoots, flower buds and stems. The milkweed fibers can be used to make fabric or rope. Pleurisy weed does have a darker side, however. The alkaloids it contains include some that can be toxic in the mature plant. It is considered toxic to livestock, and not recommended for use by pregnant or breastfeeding women, or for children.
