Task: Sentiment Analysis
Input (English): A friend sent me two boxes of this for Christmas.  I thought it an odd gift, as I can just go out and buy herbal tea.  Shortly thereafter, I was flung into major stress and chaos during an extreme family crisis. I started drinking this tea to help with unexpected stomach pains and it worked!  Not only that, during this time, other family members got physically ill, but I was able to carry on without catching the bug.  Since then, I'm a believer.  I make this as iced tea for daytime and drink a cup at night before bed. 
 Polarity: Positive
Output (English): True
