Resolved Question: Does WU YI/OOLONG/WULONG TEA actually work for loosing weight?

I was thinking of purchasing WU YI OOLONG WULONG TEA from ebay for cheap but i dont know much about it. Does anyone know if it actually works for loosing weight? Does it have any side effects like stomach cramps or diahorrea? Is it better than green tea?
Thanks.
