I just read a BBC story about a man who nuked his liver by taking concentrated green tea capsules. He requires a full transplant and four years later his kidneys are failing and he has chronic abdominal pain. It seems that one or more compounds in green tea (safe as a beverage, problematic as a concentrate) may negatively impact liver function in some genetically vulnerable populations. Truthfully though, it’s not known exactly what happened, only that it does happen.
