from all the descriptions of pu erh tea (cake, washes away fats, pungent) it sounds like the tuocha tea I drink from the Yunnan province. There is a brand that is supposed to be the best and it comes in a big round cake (like a bowl) in a green circular paper box that has Tuocha written in red. I've now seen them come in mini cakes (still bowl shaped) and in regular boxes with the same red text. It comes in green tea, oolong and ...something flavors. I think they're mixes. Anyhow, it is true that it washes away the fats in the body and is great to drink after an oily meal. However, be forewarned that a) it's too strong for you and/or b) it's your first time drinking, you'll probably have to run to the toilet within a half hour. A cousin of mine lost a lot of weight drinking a cup of it every day. Supposedly, he lost his belly fat that way. The bowl brick I buy can be found in a lot of Asian markets (Chinese in particular) but not all markets carry it. They used, but of late, I'm finding fewer carry it, favoring other brands or they're switching to the mini versions in the box. Either way, I've been told the best quality comes from Yunnan province. Happy drinking to a healthier you!
