Health Canada warns of liver injury risk linked to green tea extract
November 22, 2017

After completing a safety review of green tea extract in natural health products, Health Canada is strengthening warnings on labels of these products to avoid the risk for liver injury, according to a press release.

Products with green tea extract, promoted to help manage weight and as a source of antioxidants, are mainly authorized for adult use only and generally considered safe, according to the release.

Although Health Canada already includes the risk for liver-related injury on its label, the continuing global reports of serious liver injury cases prompted the department to perform a safety review to clarify the risk and determine the necessity of additional safety measures, according to the release. The results confirmed a link between green tea extract and rare serious liver-related adverse responses; however, why some people are more susceptible than others to liver injury remains unclear, per the release.

In response of these findings, Health Canada requests that companies update all affected natural products labels to warn about the rare, but serious, cases of liver injury reported after green tea extract use and to advise against use of these products if symptoms of potential liver damage appear, per the release.

The department has also updated the Green Tea Extracts monograph to include the revised warning and requests that license holders of natural health products containing green tea extract as a medical ingredient either remove the extract from the products and revise the label with indication that it is for adult use only, according to the release.

针对这些调查结果,加拿大卫生部要求公司更新所有受到影响的天然产品标签,以警告使用绿茶提取物后报告的罕见但严重的肝损伤病例,并建议如果潜在的肝损伤症状使用这些产品出现,每个版本。

看来“纯天然” 也不靠谱,天然的普通绿茶没有任何问题;
但提纯和萃取后,就本质可能是原物的几十倍的放大;
所以,对于这种保持纯天然纯植物的萃取,还是谨慎的态度
