Your pot should be the one with a metal heating plate at the bottom. In fact, this pot is not suitable for boiling traditional Chinese medicine, because the medicinal materials will come into contact with the metal heating plate, which will affect the efficacy. I suggest you use that all-glass health pot to decoct medicine. All-glass is the glass below it, and there is no metal at all. However, there are two kinds of all-glass, one is black film heating, which is unsafe and easy to leak electricity, and the other is 3C certified.
