This genus is native to temperate regions of [[Asia]], [[Europe]], and [[North America]]. The name ''Leonurus'' derives from the Greek words ''leon'' (lion) and ''oura'' (tail), referring to the shape of the plant's leaves that resemble a lion's tail. Motherwort is widely recognized for its traditional use in [[herbal medicine]], particularly for treating heart conditions and as a sedative.<br />
<br />
== Description ==<br />
Plants in the ''Leonurus'' genus are [[perennial plant|perennial]] [[herb]]s, characterized by their square stems, opposite leaves, and pink to purple [[flower]]s arranged in dense whorls along the upper part of the stem. The leaves are often deeply lobed, resembling the tail of a lion, which is reflected in the genus name. The flowers are small, with a distinctive upper lip shape, attracting a variety of [[pollinator]]s, including [[bee]]s.<br />
