Description edit
It's commonly found on the sides of roads, and in the wilderness, throughout Japan, Korea, and parts of China. It grows to about 20-40 centimeters tall. It has yellow, usually five petaled flowers that bloom in the spring. Its rhizome is short, its stem is thin and upright, and the stem branches near the top. Its leaves are broad and lanceolate. It prefers partial shade. In Japan, it's known as “nigana” which literally translates to English as “bitter greens.” However, other plants of this genus are also known as “nigana” in Japanese, so it's not a specific term.[4]
Uses edit
Used as a folk remedy in Japan where it's said to relieve indigestion and reduce inflammation. The whole plant is used as a remedy including roots. The plant is harvested during its flowering period, and then washed and dried before consuming.[5]
