Chicory

Common chicory, Cichorium intybus, is a somewhat woody, perennial
herbaceous plant of the dandelion family, usually with bright blue flowers, rarely white or pink. Many varieties are cultivated for salad leaves, chicons (blanched buds), or roots (var. sativum), which are baked, ground, and used as a coffee substitute and additive. It is also grown as a forage crop for livestock. It lives as a wild plant on roadsides in its native Europe, and now common in North America, China, and Australia, where it has become widely naturalized.

"Chicory" is also the common name in the United States for curly endive (Cichorium endivia); these two closely related species are often confused.

Root chicory contains volatile oils similar to those found in plants in the related genus Tanacetum which includes Tansy, and is similarly effective at eliminating intestinal worms. All parts of the plant contain these volatile oils, with the majority of the toxic components concentrated in the plant's root.

Chicory is well known for its toxicity to internal parasites. Studies indicate that ingestion of chicory by farm animals results in reduction of worm burdens, which has prompted its widespread use as a forage supplement. Only a few major companies are active in research, development, and production of chicory varieties and selections, most in New Zealand.

Chicory (especially the flower), used as a folk medicine in Germany, is recorded in many books as an ancient German treatment for everyday ailments. It is variously used as a tonic and as a treatment for gallstones, gastro-enteritis, sinus problems and cuts and bruises. (Howard M. 1987). Chicory contains inulin, which may help humans with weight loss, constipation, improving bowel function and general health. In rats, it may increase calcium absorption and bone mineral density.

Chicory has demonstrated antihepatotoxic potential in animal studies.

Chicory has been listed as one of the 38 plants that are used to prepare Bach flower remedies, a kind of alternative medicine. However, according to Cancer Research UK, "there is no scientific evidence to prove that flower remedies can control, cure or prevent any type of disease, including cancer".
The Cherokee use an infusion of the root as a tonic for nerves. Iroquois use a decoction of the roots as a wash and apply a poultice of it to chancres and fever sores.

Common chicory is also known as blue daisy, blue dandelion, blue sailors, blue weed, bunk, coffeeweed, cornflower, hendibeh, horseweed, ragged sailors, succory, wild bachelor's buttons, and wild endive. (Note: "Cornflower" is commonly applied to Centaurea cyanus.) Common names for varieties of var. foliosum include endive, radicchio, Belgian endive, French endive, red endive, sugarloaf, and witloof (or witlof).

When flowering, chicory has a tough, grooved, and more or less hairy stem, from 30 to 100 cm (10 to 40 in) tall. The leaves are stalked, lanceolate and unlobed. The flower heads are 2 to 4 cm (0.79 to 1.6 in) wide, and usually bright blue, rarely white or pink. Of the two rows of involucral bracts, the inner is longer and erect, the outer is shorter and spreading. It flowers from July until October. The achenes have no pappus (feathery hairs), but do have toothed scales on top.
