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...........

绿茶伤肝？正常喝的话并不会，但要小心保健品
欧洲食品安全局（EFSA）发布了关于绿茶儿茶素安全性的科学报告[1]，主要研究了儿茶素潜在的肝毒性。调查的起因是，一些病例报告和干预试验观察到，摄入绿茶儿茶素和肝脏转氨酶升高之间有关联，而转氨酶升高可能提示肝功能损伤。1
在梳理研究证据以后，这份报告的主要结论是，每日摄取800毫克或以上儿茶素（准确来说是EGCG，后文会解释）可能会导致转氨酶升高。不过，如果把这样的结论解读为“喝绿茶伤肝”，那就是断章取义了，因为正常喝绿茶不太可能摄入那么多儿茶素。倒是吃绿茶保健品的人得留心了。…………
