:"Cassia humilis" ''redirects here. This taxon may also refer to other species; see below.'' ''Senna obtusifolia'' (Chinese senna, American sicklepod or sicklepod) is a legume in the genus ''Senna'', sometimes separated in the monotypic genus ''Diallobus''. It grows wild in North, Central, and South America, Asia, Africa, and Oceania, and is considered a particularly serious weed in many places. It has a long-standing history of confusion with ''Senna tora'' and that taxon in many sources actually refers to the present species. The green leaves of the plant are fermented to produce a high-protein food product called "kawal" which is eaten by many people in Sudan as a meat substitute. Its leaves, seeds, and root are also used in folk medicine, primarily in Asia. It is believed to possess a laxative effect, as well as to be beneficial for the eyes. As a folk remedy, the seeds are often roasted, then boiled in water to produce a tea. The plant's seeds are a commercial source of cassia gum, a food additive usually used as a thickener and named for the Chinese Senna's former placement in the genus ''Cassia''. Roasted and ground, the seeds have also been used as a substitute for coffee. In traditional Korean medicine, they are called ''gyeolmyeongja'' (결명자) and usually prepared as tea. They are also used in Kampō (traditional Chinese medicine in Japan), where they are called ''ketsumei-shi'' (ケツメイシ, 決明子) or by their Chinese name ''jué míng zǐ'' (traditional: 決明子, simplified: 决明子). == Names, taxonomy and identifier == Apart from "sicklepod" and "Chinese senna", ''S. obtusifolia'' has a wide range of common names. It is also known in English as Foetid Sassia (or "cassia"), Sickle Senna, Coffeeweed or Arsenic Weed, and somewhat ambiguously as "blunt-leaved senna", "coffee pod" or "java bean". The scientific name means "blunt-leaved senna", with ''obtusifolia'' coming from Latin ''obtusus'' ("dull", "blunt") + ''folium'' ("leaf"). Names in its native range are also: * Chinese: pinyin: ''jué míng zi'' () * Japanese: ''ebisu-gusa'' ("''Ebisu'' grass": エビスグサ; 胡草; 恵比須草) * Korean: ''gyeolmyeongja'' (hangul: ; hanja: ) * Portuguese: ''fedegoso'' (also used for ''Senna macranthera'' and others) * Hindi: ''chirauta'' ''chokad'' * Vietnamese: ''quyết minh tử'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Senna obtusifolia」の詳細全文を読む スポンサード リンク
