+'''''Asarum''''' (''[[Syllable stress of Botanical Latin|Á-sa-rum]]'') is a genus of plants in the birthwort family [[Aristolochiaceae]], commonly known as '''Wild ginger'''.
+
+Asarum consists low-growing herbs , that are distributed over the north temperate zones with most species in Asia (mainly China, Japan and Vietnam), North America and one species in Europe. Biogeographically, ''Asarum'' originated in Asia
+
+They have characteristically kidney-shaped leaves, growing from creeping [[rhizome]]s. They bear small, [[wikt:axil|axil]]lary brown or reddish flowers.
+
+''[[Asarum canadense]]'' is native to the forests of eastern [[North America]]. It is found from the [[Great Plains]] east to the [[Atlantic Ocean|Atlantic]] Coast, and from southeastern [[Canada]] south to approximately the [[fall line]] in the southeastern [[United States]].
+
+''[[Asarum caudatum]]'' is found in [[British Columbia]] south through [[Washington]] and [[Oregon]] to central [[California]], and from the [[Coast Range]] east to western [[Montana]].
+
+The plant is called wild ginger because the [[rhizome]] tastes and smells similar to that of [[ginger root]], but the two are not particularly related. The root can be used as a [[spice]], but is a potent [[diuretic]], or urinary stimulant. ''Asarum canadense'' and other species in the genus contain the [[nephrotoxic]] rodent [[carcinogen]] [[aristolochic acid]], which is the FDA warns against consuming.<ref>U.S. Food and Drug Administration |url=http://www.fda.gov/Food/DietarySupplements/Alerts/ucm096388.htm</ref>

+The birthwort family also contains the genus [[Aristolochia]], known for [[carcinogens]].
