No decoction is gradually accepted by the public, mainly because it is easy to carry and convenient to take. But how to take it, I think: it is not recommended to use warm water or boiling water, it is recommended to brew with cold water (tap water or pure water can be used), stir thoroughly and then boil on low heat (microwave heating is not recommended, because the unmelted particles are easy to burn paste), stir while cooking to prevent the sticky bottom from burning paste. Can be cooked for 1 to 3 minutes the efficacy may be better. The advantages of this serving method: 1, not easy to produce sediment; 2, the taste is more pure; 3, closer to the traditional Chinese medicine compound mixed decoction.
