Sixty images of Foxglove, Digitalis, Comon Foxglove, Digitalis purpurea, a biennial or short-lived perennial, a well-known ornamental for flower and herb gardens. Native to Europe and widely cultivated throughout the world, in the American Northwest and Northeast it is widely naturalized. In 1785, William Withering, an English physician, brought foxglove’s diuretic and dropsy-relieving properties to light, an effect induced by the highly toxic, cardiac stimulant glycosides in the plant. By the late nineteenth century, it was widely prescribed by physicians as a cardiotonic and diuretic. Today, isolated digoxins are used as a cardiac stimulant for cardiac insufficency and rythym abnormalities. Dropsy or edema from a weak heart, characterized by leg swelling and accumulation of fluids is a symptom. The purified digoxins are used in highly controlled dosages, either orally or as injections in coventional medicinal. The herb itself is no longer used as a crude drug as the therapetuic and toxic dosages are very close quantitatively and can lead to life-threatening symptoms. Considered a poisonous plant.
