There was a patient with no obvious cause of malaise, poor nausea, and yellow urine, who went to the hospital and found abnormal liver function with ALT over 1000 IU/L, suggesting severe liver injury. Careful examination did not reveal the common causes of hepatitis, such as hepatitis A, B, C, and E. The patient also had no recent history of heavy alcohol consumption or drug use, however, the patient had been taking a kind of hair brightening nutritional powder purchased from a supermarket for the last 3 months or so because he had gray hair (made from grain substances such as He Shou Wu, black sesame, black beans and black rice ground on site, of which He Shou Wu is a drug that has been documented to cause liver injury). After analysis, the patient’s liver injury could not be ruled out to be related to the consumption of this nutritional product. The nutritional product contains He Shou Wu, which has been reported to cause liver injury. On July 16, 2014, the State Food and Drug Administration issued a warning message “Concerned about the risk of liver injury caused by oral intake of He Shou Wu and its prescriptions”. In recent years, there have been reports of liver injury caused by oral administration of Radix et Rhizoma Polygoni and its prescriptions, which may be related to overdose, long-term continuous use, or individual idiosyncrasies cannot be excluded. It is clear that health products should not be taken at will, and if you want to take them, you must understand their ingredients, especially those containing Chinese herbs, which need to be used with caution before understanding their properties.
