Nanjing Gulou Hospital received an aunt Zhong from Fujian, who began to experience abdominal distension and discomfort more than a month ago. Aunt Zhong had been plagued by chronic pharyngitis for many years, and before the Spring Festival in 2023, she returned to her hometown in Fujian.

She found a "little red" rhizome from a neighbor's house, sliced and boiled water, and drank it as "herbal tea" every day. After drinking for a month, she began to have abdominal distention, fatigue and other uncomfortable symptoms. The examination found abnormal transaminases, jaundice, and ascites.
