To cook traditional Chinese medicine, do you choose the right equipment for boiling medicine in your home?

   Compared with the decoction in the hospital, taking the Chinese medicine home and boiling it is indeed a bit more troublesome, but it can be cooked more delicately. However, in the process of boiling Chinese medicine, in addition to mastering the decoction methods such as first and second decoctions, it is also very important to choose the right equipment for boiling the medicine. The Chief Chinese Pharmacist Zhao Zhihui of the First Affiliated Hospital of Guangzhou University of Chinese Medicine will teach you how to choose.

  Avoid iron, copper, aluminum, tin, etc.

  【Iron pot】The chemical properties of iron are unstable. During the decoction process, it is easy to chemically change with the tannins, oils, alkaloids, coumarins and other ingredients contained in traditional Chinese medicine, which affects the efficacy of the medicine, and even the liquid It is green and black with astringent and fishy smell.

  【Copper pot】

   (1) The general copper pot is an alloy composed of copper and zinc. Studies have found that the general copper pot decoction can detect trace amounts of copper ions. Copper ions will promote the oxidation of unsaturated carbon chain oils and vitamins A, C, D and other components in traditional Chinese medicine, and lose their biological activity. It will cause irritation and toxicity to the mucous membrane, so ordinary copperware is not an ideal decocting utensil.

   (2) Red copper is a simple substance of copper, with a melting point of 1083°C, no allotropic transformation, and the mass of the same volume is about 15% heavier than ordinary steel. Because of its relatively stable physical and chemical properties, the copper pot made of red copper is one of the commonly used utensils for making paste recipes. But the disadvantage is that the price is higher.

  [Aluminum pot] It is not resistant to strong acids and alkalis. Aluminum ions can be detected in the decoction of pH1~2 or pH10, which may even aggravate certain diseases caused by high aluminum content in the body.

  Yi casserole, ceramic pot, stainless steel pot, etc.

  【Casserole】Uniform heat transfer, stable chemical properties, and low water evaporation. But it also has the small shortcomings of many pores and textures, easy to absorb various pharmaceutical ingredients and odor.

  【Ceramic pot, enamelware】It is not easy to stick to the pot and will not chemically react with the active ingredients of Chinese medicine. It is easy to clean and will not leave medicinal smell. It has the function of keeping fresh and is a good decoction device.

  【Stainless steel pot】It has the characteristics of fast heat transfer, acid and alkali resistance, corrosion resistance, and long service life. It is the basis of a modern multifunctional Chinese medicine decoction device.

  [Automatic Chinese Medicine Pot] The automatic decocting pot currently available on the market is designed with a microcomputer to monitor automatic decocting, preventing boiling overflow, automatic heat preservation, and equipped with civil fire and military fire. In addition to being used for decocting, it can also be used Use it to boil water, stew tonics, make soup, etc. It adopts separate heating, the electric heating device is designed outside the inner tank, and the structure is compact. It is also a good decoction appliance. However, it is worth noting that after decoction of the medicine, the heat preservation function should not be used, and the liquid medicine should be poured out in time to prevent the liquid medicine from sucking back.
