I believe alot have been discussed about whether Wulong Tea or Wu Long Tea is the same as oolong tea. This is a fact that all the above refers to the same tea. As stated in other postings, oolong or Wulong tea is just a tea category with about 50% fermentation level compared to Green Tea (0% fermentation or mininal level). when we talk about different wulong/oolong tea, we are referring to the various grades of wulong/oolong tea due to different processing method and plantation origin. So i believe if anyone call their wulong tea as ??? wu long, it should be referring to their brand name.
As for weight loss....(Oh No..Wulong Tea & Weight loss question again !!)...there is no definite answer to it. some people claimed to have lost XX amount while others said there are no effects. Its up to you whom to believe although I would rather you try to enjoy wulong/oolong tea as the tea itself instead of its potential weight loss properties. I drink wulong tea daily and i really enjoy it.
