[Comments] 1. Reed root is mainly used in the following two aspects in clinical practice. It can clear lung heat and remove phlegm and pus, and can also clear stomach heat and produce fluid to stop vomiting. Although it is cold in nature, it tastes sweet and light and has weak effect. It can only be used as an auxiliary medicine to clear the lungs and stomach. However, it has an advantage, that is, it is not greasy in nature, produces fluid without clinging to evil. It can be used for all febrile diseases with heat clinging to the defense and qi, or if there are symptoms of thirst after fever and damage to fluid.
2. Reed stem soup originally used the above-ground stems of reeds, not the rhizomes of reeds, but because it is not available in general pharmacies, reed roots are used instead. It has been used clinically for a long time, which shows that reed stems and reed roots have the same effect. Therefore, fresh reed roots and reed stems can be collected and used together in rural cooperative medical stations, which can not only save manpower for digging reed roots, but also expand the source of medicine.
