Quick Summary
Yellow corydalis, also known as rock fumewort (C. lutea), is a species of herbaceous flowering plant belonging to the genus Corydalis within the poppy family (Papaveraceae). This plant, native to southern Europe, is a popular garden ornamental, typically growing to about 9 inches tall and producing sprays of yellow, tubular flowers.1
The genus Corydalis comprises over 400 species found throughout north temperate areas, with a high diversity concentrated in the Sino-Himalayan region.

While the root tubers of some Asian Corydalis species are used in traditional medicine, scientific studies to support their efficacy are lacking.1
