I drank these flavors: Poria cocos, cassia seed (or Gynostemma pentaphyllum), hawthorn, Polygonatum sibiricum and lotus leaf. Put a few grams of tea at a time. It can be brewed repeatedly all day. Just try it.
Of course, diet and exercise are better, or diet and exercise are the basis.
This tea is a little cold. Don't eat cold things like bingo at ordinary times, or you may have a stomachache.
