Legend has it that yarrow (Achillea millefolium) was named after Achilles, the Greek mythical figure who used it to staunch the bleeding wounds of his soldiers. Popular in European folk medicine, yarrow has traditionally been used to treat menstrual ailments and bleeding hemorrhoids. Like chamomile, its distant botanical relative, yarrow is also a common herbal remedy for bloating, flatulence, and mild gastrointestinal cramping.

Plant Description

Yarrow flourishes in a sunny and warm habitat, and is frequently found along meadows and roadsides, as well as on dry, sunny slopes. It grows as a simple, erect, and hairy stem that reaches a height of 0.1 to 1.5 meters. The entire plant (with the exception of the fruit) is draped in white, silky hairs. Growing from underground runners are tough, angular, horizontal stems that bear flowers.

Yarrow blooms between June and September. The flowers are typically white, but either pink or pale purple flowers are common in mountain areas. The petals are densely arranged in flattened clusters, and the leaves look like feathers.
