When buying a health pot, be sure to buy all-glass ones, not metal ones. All-glass means that the pot body is made of high borosilicate glass (just like the cup we usually drink), and the bottom is also glass, without metal and silica gel. This kind of health pot, the water and ingredients in the cooking process are not polluted, keep pure and true nutrition, and escort your health. Metal bottom pot means that this pot has the structure of metal heating plate+glass pot body+silicone ring. Metal and rubber rings are soaked in water to boil, and the boiled water is equal to glue and metal water. If you take this pot to decoct medicine, it will be even more unreliable. Metals will have adverse reactions with medicinal materials, which will seriously affect the curative effect. In addition, there will be gaps between the metal plate, apron and glass, which is easy to hide things and difficult to clean. Health pot is a national compulsory certification product, which must have 3C certification. Simply put, as long as it is an all-glass healthy pot with 3C certification, it is a safe and healthy pot.
