[Hepatotoxicity of dietary supplements and herbals is mostly unknown].

The use of herbals and dietary supplements is considerable and increasing. Several cases of serious hepatotoxic side effects and a wide range of clinical manifestations have been described. As toxic hepatitis often arises in an unpredictable and dose-independent manner, diagnosis may be difficult. Increased public awareness of the potential risks of herbals and dietary supplements is desirable in order to ensure that suspected adverse effects and interactions are formally reported.
