Curculigo is the rhizome of the herbaceous plant Curculigo orchioides Gaertn. from the Amaryllidaceae family. It was first introduced to China during the Tang Dynasty along with Buddhism. At that time, it was used as a kidney-tonifying and yang-strengthening medicine and was widely consumed. Later, people discovered that this herb is toxic, and the trend of indiscriminate consumption gradually subsided. As stated in the "Poem of Curculigo": "The envoy took it away just yesterday, and today people come seeking epitaphs," indicating that many people died from the indiscriminate use of Curculigo at that time. Today, Sichuan produces the largest quantity. It is harvested in spring and autumn, dried in the sun, and used either sliced raw or after soaking in rice-washed water and slicing.
