Can Chinese medicine soak in stainless steel thermos cup for one day?

When the traditional Chinese medicine is put into a thermos bottle and poured into boiling water, protein and starch in the traditional Chinese medicine will solidify, blocking the capillary channels on the surface of the traditional Chinese medicine, so that water cannot enter and cells are not easy to break. Even if there is, the effective components will remain in the condensed solid, which is not easy to penetrate.

Moreover, the water temperature in the thermos has been dropping. With the decrease of water temperature, it is difficult to dissolve the general Chinese medicine ingredients, even a small amount of effective substances dissolved when just washed into boiling water will form precipitation. Therefore, soaking traditional Chinese medicine in a thermos bottle can't make the effective components dissolve out and can't achieve the therapeutic purpose.

Extended data:

Chinese medicine attaches great importance to the instruments, water and fire used in decocting drugs. If any link is not done well, it will affect the curative effect. Especially when choosing decocting instruments, we should pay attention to three conditions:

1, that is, the capacity of the instrument should be moderate, which is convenient for drug soaking and boiling;

2, the container should have a cover to prevent the loss of medicinal properties with water evaporation and ensure the dissolution of drugs;

3. The parts of the appliance should be stable and will not react chemically with the liquid medicine. Therefore, the utensils with the best decocting effect belong to crock, pottery and casserole, which have uniform heat conduction, mild heat, long heat preservation time and stable chemical composition.

However, metal utensils are easy to react with the effective components of traditional Chinese medicine, which leads to discoloration of traditional Chinese medicine decoction, reduced efficacy and even side effects. If hawthorn contains tannic acid, it can react with metal and iron utensils to generate ferrous tannic acid, which will cause adverse reactions such as nausea, vomiting and abdominal distension after being absorbed by human body. Therefore, we should try to avoid frying Chinese medicine with metal utensils.
