Spigelia marilandica, the woodland pinkroot[1] or Indian pink[2][3] is a herbacious perennial wildflower in the Loganiaceae family[2] native to inland areas of the Southeastern and Midwestern United States.[3]
It flowers in late spring and early summer[3] and tends to be found in low moist woods, ravines, or stream banks in partial or full shade.[2] The flowers are red, erect, tubes with a star-shaped yellow center at the tip.[4] It will grow 30–61 cm (1–2 ft) high with a spread of 15–46 cm (0.5–1.5 ft).[2]
It is used as an ornamental plant,[5] more popular in the UK and Europe than its native U.S.[4]
Its dried roots are used as an anthelmintic (dewormer), and are followed by a saline aperient to avoid unpleasant side effects and ensure that the toxic root is expelled along with the worms.[6] The roots are also a narcotic hallucinogen, but the alkaloid spigiline, which is largely responsible for both its hallucinogenic and medicinal action, can cause increased heart action, vertigo, convulsions and death if overdosed.[6]
