If the quantity of Chinese herbal medicines is too large, some of them can be separated and decocted separately, and then use the medicinal broth to decoct the rest of the medicines, or decocted in batches, or decocted on behalf of others, etc. Please consult your doctor for details. If the portion size of Chinese medicine is too large, you can separate the larger herbs such as grasses and leaves and decoct them separately, and then use the boiled broth to decoct the rest of the medicine, paying attention to the fact that some medicines should not be decocted for a long period of time, such as mint, honeysuckle, ephedra, and so on. Alternatively, they can be decocted separately in batches and subsequently mixed together, paying attention to controlling the amount of water so as not to have too much water, which may affect the efficacy of the medicine. Or ask hospitals, pharmacies and other places to make the decoction on your behalf, saving you the process of boiling the medicine yourself. The correct method of boiling Chinese medicine is as follows: before the first decoction, add water not exceeding the herbs, soak for 30~60 minutes, take out the medicinal broth after decoction, add water for the second time for 1/3~1/2 of the first decoction, decoct again, and mix the two decocted medicinal broths to be taken in separate doses. Some herbs have special texture, so the method of decoction is also special, please pay attention to read the prescription in detail. Generally speaking, fresh and clean water such as tap water, well water and distilled water is preferred for decoction. It is better to use casserole and tile pots for decoction, and avoid using metal pots and pans such as copper, iron and aluminum, in order to avoid chemical changes of Chinese medicines. Please consult a professional Chinese medicine practitioner or pharmacist for specific decoctions, and go to the hospital if you feel unwell.
