Clears thick, stuck mucus from deep in the lungs.

A towering perennial, often taller than a person, with huge downy leaves and shaggy yellow sunflowers; its thick root smells of violets and camphor. Elecampane warms and strengthens the lungs, brings up heavy, stubborn phlegm, and fights the infections that settle in for weeks.

Folklore

Helenium honors Helen of Troy, and one legend says the plant sprang where her tears fell. Pliny wrote that the empress Julia Augusta ate a little preserved elecampane root every day for her digestion. Londoners sucked on elecampane candy for coughs into the twentieth century. In 1804 the chemist Valentin Rose isolated a new starch from the root, and it was named inulin after the plant's genus.

How to grow

A hardy, long-lived perennial for full sun and rich, moist soil. Give it room; one plant can reach six to eight feet. Dig roots from plants two or three years old in autumn, then chop them while fresh, since they dry rock hard.

In the wild

Native to Europe and western Asia and naturalized along roadsides, old farmsteads, and damp field edges in eastern North America.
