There should be no such service, just buy a health pot to decoct medicine yourself. I use the all-glass pot of Wandiwang 2 1A233. This pot is really good. It is necessary to share with you: First of all, it is all glass, and there is no metal heating plate in it. The medicinal materials do not contact metals at all, with a capacity of 2.5 liters. The boiling procedure is very good. The first decoction is divided into four bowls of water 1 bowl of water; Stir-fry 3 bowls of water into 1 bowl of water; Stir-fry 2 bowls of water 1 bowl of water. After selecting the program by yourself, it is fully automatic and automatically keeps warm after frying. It's really awesome.
