Japanese: クサノオウ - くさのおう
Celandine - Grass king

A biennial plant of the Papaveraceae (APG classification: Papaveraceae). It is commonly seen on roadsides and other places. It is about 60 cm tall. The stems, petioles, and veins are covered with white hairs. Yellow juice comes from the stems and leaves. The name Celandine (Kusano-o) comes from this. The leaves are alternate, 1-2 times pinnately compound, and have blunt lobes. In May and June, it produces umbels and several yellow flowers. It has two green sepals and four yellow petals. It has many stamens and one pistil. The capsule is long and slender, with two lobes. In traditional Chinese medicine, the whole dried plant is called Hakukutsusai and is used as an analgesic and antispasmodic. It is widely distributed from Hokkaido to Kyushu, and further into the temperate zones of East Asia. The genus Celandine has four petals, many stamens, a long capsule, and latex, and in addition to Celandine, there is also Keramisium, although Keramisium is often classified as a separate genus, Keramisium.

ケシ科(APG分類:ケシ科)の越年草。道端などでごく普通にみられる。高さ約60センチメートル。茎、葉柄、葉脈上には白毛が生えている。茎や葉から黄色の汁が出る。クサノオウ(草黄)の名はそのことによる。葉は互生、1~2回の羽状複葉、裂片は鈍頭。5~6月、散形花序を出し、数個の黄色の花を開く。萼片(がくへん)は緑色で2枚、花弁は黄色で4枚。雄しべは多数、雌しべは1本。蒴果(さくか)は細長く、2裂する。漢方では全草を乾かしたものを白屈菜(はっくつさい)と称し、鎮痛、鎮痙(ちんけい)薬として用いられる。北海道から九州、さらに東アジアの温帯域に広く分布する。クサノオウ属は、4枚の花弁、多数の雄しべ、細長い蒴果、乳液をもつ、などの特徴を備え、クサノオウのほかにヤマブキソウがある。ただし、ヤマブキソウはヤマブキソウ属として別の属にされることが多い。
