 In a new case study in the British Medical Journal Case Reports, the unidentified patient came to her doctor with nausea, joint pain and nonspecific abdominal pains. Physicians gave the teen antibiotics, thinking she had a minor infection and sent her home. But she came back to the emergency room jaundiced with worsening symptoms. 
  
 The girl, 16, then told her London doctors she had started drinking green tea bought online in a bid to lose some weight. 
  
 "I had only lost a couple of pounds but then started having horrible pains in my joints, and felt very dizzy and sick," she said in the study. "I was very scared when I was admitted to hospital and had lots of tests. I didn't fully understand what was going on at the time." 
  
 After doing multiple tests searching for viral causes to her illness, the teen's doctors realized she had acute hepatitis, or an inflamed liver. Once the girl stopped drinking the tea and was given intravenous fluids and medication, she quickly recovered. 
  
 While the team did not test the tea for other substances, they theorized the tea itself could have contained materials that affected the girl's liver function. 
  
 "We acknowledge that green tea is predominantly a very safe and healthy drink, with antioxidant properties," the case study authors wrote, explaining secondary additives may cause harm. "This raises the possibility that it is the addition of other chemicals causing hepatotoxicity, (chemical-driven liver damage) particularly in preparations used for weight loss." 
  
 They also said pesticides on the green tea leaves could potentially cause problems for tea drinkers. 
  
 Dr. Donna Seger, head of the Tennessee Poison Center in Nashville, said she's always concerned when people buy herbal supplements or tea over the Internet without knowing much about where it came from. 
  
 "I think there are still tons of people who don’t realize that because it’s natural," doesn't mean it can't hurt you, Seger said of unlisted herbs or other materials in products. "They can have very significant toxicity." 
  
 Seger said people often turn to herbal supplements for weight loss and body building and that the liver, used to filter out toxins, is often the first organ to signal something is wrong. 
  
 "You tell me anyone has gotten anything over the Internet [she says check] the liver function," Seger explained. 
  
 The unidentified patient, who was born in Yemen, said she intended not to repeat the mistake. 
  
 "I will never buy any online tea again or any weight-loss pills," she wrote. "People should be more aware of what they are buying and the side effects." ||||| It is the drink of choice for the health-conscious, but doctors have warned of the hidden dangers of green tea after a teenage girl who drank three cups a day for three months contracted acute hepatitis. 
  
 The 16-year-old complained to her GP of dizziness, nausea, stomach and joint pains. The doctor initially thought she had a urinary tract infection and she was sent home with antibiotics. 
  
 Two days later her symptoms had worsened and she went to the A&E department of Birmingham University Hospital. 
  
 By this point, she was suffering from jaundice, causing her skin and the whites of her eyes to turn yellow, according to doctors who described the case in the journal BMJ Case Reports. 
  
 Her condition was deemed so serious that she was referred to the acute medical team, who believed she was suffering from hepatitis, a swelling or inflammation of the liver. 
  
 It can be caused by a virus, or when the liver is exposed to harmful substances such as alcohol. 
  
 The girl, who is originally from Yemen but was not named in the report, said she had not recently consumed alcohol or drugs, including over-the-counter prescription drugs such as paracetamol, nor had she travelled abroad.

 But she recalled she had ordered two boxes of Chinese green tea online, and drank three cups a day for three months. 
  
 “I had bought the green tea over the internet to lose weight,” the teenager said. 
  
 “Most of the ingredients of the tea I bought were written in Chinese. 
  
 "I had only lost a couple of pounds but then started having horrible pains in my joints, and felt very dizzy and sick.” 
  
 The authors of the report said infections developing as a result of excessive herbal tea drinking were a “rare but recurring theme”. 
  
 Green tea, which is rich in a depression-fighting animo acid called theanine, has previously been lauded for its health benefits. 
  
 It has been suggested that its antioxidants help with breast, lung and stomach cancers. It has also been claimed that a cup can protect against dementia and Alzheimer’s and improve cholesterol levels. 
  
 But doctors identified green tea as the “causative agent” of the girl’s hepatitis, and ordered her to stop drinking it immediately. 
  
 “After ceasing green tea consumption, there was a rapid and sustained recovery of her hepatitis,” the report’s authors wrote. 
  
 They said it was possible that the addition of chemicals to the tea, perhaps to aid weight loss, or the use of pesticides on tea trees had contaminated the infusion. 
  
 “There is potential for pesticide-induced hepatitis to exist, especially from less regulated products ordered from developing countries over the internet,” said the report. 
  
 But the authors added: “We acknowledge that green tea is predominantly a very safe and healthy drink, with antioxidant properties.” |||||

A 16-year-old girl in England decided she was going to lose weight by drinking green tea, so she ordered two boxes online, the Telegraph reports. Most of the ingredients were written in Chinese, but the girl spent the next three months drinking three cups a day. According to ABC News, she had lost only a few pounds when she started suffering from nausea and joint and abdominal pains. She would eventually develop jaundice. "I was very scared when I was admitted to hospital and had lots of tests," the girl says in a report published Wednesday in the British Medical Journal Case Reports. "I didn't fully understand what was going on at the time." The initial suspicion was a urinary tract infection, but it turns out she had acute hepatitis. Doctors gave the girl intravenous fluids and medication—and made her stop drinking the tea—and she recovered quickly, ABC reports. According to the Telegraph, green tea has been rumored to be help everything from depression to breast cancer to dementia, thanks to its antioxidants. The report's authors even "acknowledge that green tea is predominantly a very safe and healthy drink." And while they didn't test the girl's tea, they believe chemical additives or pesticides were likely the cause of her hepatitis. One expert tells ABC that consumers need to be careful when buying herbal supplements or tea over the Internet. It's a lesson one 16-year-old girl learned the hard way. "I will never buy any online tea again," she says in the report. (The right kind of green tea might reduce your risk of stroke.)
