 Prostrate evergreen perennial, up to 10cm high, native to eastern North America; slender rhizome with the smell of ginger; stems short, developing in spring, each branch with one leave; leaves dark green, reniform (kidney-shaped), downy at both sides, 5-20cm across; flowers on short stalkes near ground, solitary, dark purple-brown, campanulate; fruit a coriaceous, 6-celled capsule.
+"Flowers are quite attractive on close inspection, but bloom singly on or near the ground and are usually hidden from view by the foliage. Although not related to culinary ginger (Zingiber officinale), the roots of this plant produce a scent that is reminiscent thereof. Fresh or dried roots were used by early Americans as a ginger substitute, but the plant is not normally used today for culinary purposes."

Moerman 1986)." \\

-In 2010, the use of all plants belonging to the Asarum species in drugs was banned in Germany by decree of the Federal Institute for Drugs and Medical Devices (BfArM). The cause of this was the detection of aristolochic acid I in homeopathic mother tinctures of Asarum europaeum with approximately 0.044 to 0.13 ppm, and of Asarum canadense with approximately 127.4g/kg (about 0.13 ppm). \\
