Total score for causality: ≤ 0/excluded; 1-2/unlikely; 3-5/possible; 6-8/probable; ≥ 9/highly probable. Considered were the items for the hepatocellular type of liver injury and the data of 26 patients with normal ALT values at hospital admission, who experienced elevated ALT levels > 5 × ULN after use of herbal TCM. In the above section 4 (part 1 of the tabula) of concomitant drug(s), the following TCM herbs and drugs were considered. In the section 5 (search for alternative causes in part 2 of the tabula), the symbol of (n) denotes that the obtained result was negative, whereas (Ø) indicates that assessment was not performed. ALT: Alanine aminotransferase; AST: Aspartate aminotransferase; CT: Computed tomography; HAV: Hepatitis A virus; HBc: Hepatitis B core; HBV: Hepatitis B virus; HCV: Hepatitis C virus; CMV: Cytomegalovirus; EBV: Epstein Barr virus; HEV: Hepatitis E virus; HSV: Herpes simplex virus; MRC: Magnetic resonance cholangiography; PCR: Polymerase chain reaction; RUCAM: Roussel Uclaf Causality Assessment Method; ULN: Upper limit normal; VZV: Varicella zoster virus.
