The more than 140 species of milkweed have a long and varied history. Named Asclepius for the Greek god of healing, its medicinal uses are many. However, several species are toxic, so if the plant is used as a health remedy, the user should be well-informed in advance. The physical properties of milkweed have resulted in various uses for the stems and fluff-filled seed pods, including a wartime effort by World War II's greatest generation.
