Ardisia japonica is a species of Ardisia native to eastern Asia, in eastern China, Japan and Korea.[1]
It is a low-growing evergreen shrub 20–40 cm tall. The leaves are opposite or in whorls, ovate, 4-7 cm long and 1.5-4 cm broad, with a sharply serrated margin and an acute apex. The flowers are 4–10 mm diameter, with five (rarely six) white to pale pink petals; they are produced in racemes in late spring. The fruit is a drupe 5-6 mm diameter, red maturing dark purple-black in early winter.[1][2]
A number of cultivars have been selected for growing as ornamental plants, including 'Hakuokan' and 'Ito Fukurin' with variegated leaves, 'Hinotsukasa', with pale cream-coloured leaves, and 'Matsu Shima' with pink stems and variegated leaves.[2]
It is used as a medicinal plant in traditional Chinese medicine, where it is called zǐjīn niú (紫金牛),[1] and is considered one of the 50 fundamental herbs.[3]
Large doses of the plant as medicine can be toxic to the kidneys.[4]
