Chelidonium majus

Chelidonium majus or greater celandine (scientific name: Chelidonium majus) is a perennial plant of the family Papaveraceae native to Eurasia. It grows naturally in sunny areas from Honshu to Kyushu, and is known as a pioneer plant that grows quickly during deforestation. It grows to a height of 50 to 80 cm. The leaves are rhizomatous and rosette-shaped, with two pinnate compound leaves. In summer, it produces yellow four-petaled flowers in a spreading inflorescence from the tip of the stem. The yellow juice that comes out when the stems are broken contains protoanemonin and protopine, which can be irritating to the touch. The whole plant is poisonous, but it can also be used as a medicinal herb.
