casserole, ceramic pot, stainless steel pot and copper pot should be selected.

1. Casserole: Uniform heat transfer, stable chemical properties and small water evaporation. However, it also has many pores and textures, and it is easy to absorb various pharmaceutical ingredients and taste.

2. ceramic pot: It is not easy to paste the pot, and will not react chemically with the effective components of traditional Chinese medicine. It is easy to clean, does not leave the smell of medicine, and has a fresh-keeping function, so it is a good decocting instrument.

3. stainless steel pot: It has the characteristics of fast heat transfer, acid and alkali resistance, corrosion resistance and long service life, and is the foundation of modern multifunctional Chinese medicine decocting device.

4. Red copper pot: The red copper pot made of red copper is one of the commonly used instruments for making paste. As a simple substance of copper, its melting point is over 1, degrees Celsius, and its physical and chemical properties are stable, but the disadvantage is that it is expensive.

expanded information

iron pot, aluminum pot, tin pot and ordinary copper pot are not allowed to be used for decocting traditional Chinese medicine.

1. Iron pot: The chemical properties of iron are unstable, and it is easy to change chemically with tannins, oils, alkaloids, coumarins and other components contained in traditional Chinese medicine during the decocting process, which affects the efficacy, and even the liquid medicine is green, black, astringent and fishy.

2. aluminum pot: It is intolerant of strong acid and alkali, and aluminum ions can be detected from the decoction with pH 1 ~ 2 or pH1, even aggravating some diseases caused by excessive aluminum content in the body.

3. Copper pot: The common copper pot is an alloy composed of copper and zinc. When the liquid medicine is decocted, trace copper ions can be detected, and the copper ions will make the unsaturated carbon chain oil and vitamins A, C and D in traditional Chinese medicine oxidize and lose their biological activity, and may cause irritation and toxicity to mucous membranes, so the common copper pot is not an ideal decocting instrument.
