1 The pattern of liver injury could not be assessed as no ALP values were available and no liver biopsy was conducted; 2 Based on the updated CIOMS score as proposed by Teschke et al. [4]; 3 Tea containing liquorice, ginger, cardamom, and cinnamon. Herbs are written in bold. Numbers in brackets depict the points in CIOMS score for each compound. ASA = acetyl salicylic acid; PS = Pelargonium sidoides; ALT = alanine aminotransferase; N = enzyme value at a certain time point; CIOMS = Council for International Organizations of Medical Sciences.
