vu que le thé vert est un supplément qui est de plus en plus utilisé, si le seul cas de toxicité supposé remonte à 2006, je pense qu'il n'y a pas trop à d’inquiéter

The effect of epigallocatechin gallate on hepatocytes isolated from normal and partially hepatectomized rats.
Mezera V
Epigallocatechin gallate (EGCG) is an antioxidant found in green tea. In this study, male Wistar rats were subjected either to partial hepatectomy (PHx), or a sham operation (LAP). Twenty-four hours after surgery, hepatocytes were isolated and treated with various concentrations of EGCG for up to 72 h. We then measured markers of cell viability, oxidative stress, DNA synthesis, and caspase activity. Morphological criteria, cell viability tests, and albumin synthesis revealed toxicity starting at 10 μmol/L. DNA synthesis was higher in hepatocytes isolated from rats after PHx and inhibited by EGCG. Furthermore, EGCG increased the activity of caspases 3 and 7, seen more in hepatocytes from PHx rats. In conclusion, EGCG at a concentration of 10 μmol/L was toxic for hepatocytes isolated from both PHx and LAP rats.
