True Risk of 'Natural' Treatments Like Green Tea Supplements

A few weeks ago, a patient came to me complaining of nausea, muscle weakness and fatigue. Her urine was tea-colored despite drinking loads of water. A middle-aged woman, she seemed worried she had cancer or some deadly disease.

Her lab tests revealed significant liver dysfunction. But her symptoms were not due to liver cancer, hepatitis or other disease. It turned out she had liver toxicity from a green tea supplement that she'd heard was a "natural" way to lose weight.

When she stopped taking the supplement at my suggestion, her liver tests gradually normalized and she felt better over the course of a few weeks

I've seen the green tea issue in patients before and often witness the real-life pitfalls of eschewing traditional medicine, science and facts in favor of supplements, herbs and cleanses in the name of "natural" healing.

In an effort to be healthy, patients can easily become ensnared in the potential dangers of alternative medicine or homeopathy.

Let's be clear: Nature has a lot to offer patients...........

綠茶傷肝？正常喝的話並不會，但要小心保健品

歐洲食品安全局（EFSA）發布了關於綠茶兒茶素安全性的科學報告^[1]，主要研究了兒茶素潛在的肝毒性。調查的起因是，一些病例報告和幹預試驗觀察到，攝入綠茶兒茶素和肝髒轉氨酶升高之間有關聯，而轉氨酶升高可能提示肝功能損傷。1

在梳理研究證據以後，這份報告的主要結論是，每日攝取800毫克或以上兒茶素（準確來說是EGCG，後文會解釋）可能會導致轉氨酶升高。不過，如果把這樣的結論解讀為“喝綠茶傷肝”，那就是斷章取義了，因為正常喝綠茶不太可能攝入那麽多兒茶素。倒是吃綠茶保健品的人得留心了。…………
