It is well known that and licorice are harmonious medicines. Various Chinese medicines used in Chinese medicine prescriptions. What to do when people have different personalities? Licorice is used as a binder, just like the office director coordinates the relationship between all parties. It is included in many prescriptions.

If licorice is paired with Platycodon grandiflorum, its use will be limited, and it often appears in various prescriptions for clearing the lungs and regulating the lungs. For example, the "Sanyin Prescription" Nepeta Decoction is composed of platycodon licorice and nepeta . It treats wind-heat that fills the lungs, causing swelling and pain in the throat. If there is a stem in the throat, it will be particularly painful when swallowing. Many Chinese patent medicines, such as Tongxuanlifei Pills , Fenghanmao Granules, etc., also contain it.
People can't help but adapt a famous saying: The Qingfei prescription of running water is the same as the iron one. Although it is a bit exaggerated, they may not appear in every lung disease prescription, but their role cannot be ignored.
This is because licorice not only harmonizes various medicines, but also has the ability to clear the lungs and expel phlegm. Platycodon not only clears the lungs, removes phlegm, soothes the throat and relieves pain, but it can also be used as a vehicle to carry medicine upwards, allowing the medicine to more easily enter the lungs to clear phlegm and relieve coughs.
The phlegm in the lungs can be caused by a cold. Usually the phlegm disappears after the cold is gone. But there is a kind of phlegm that you always feel like you can’t finish vomiting even if you don’t have a cold, just like Xiaoqiang who can’t stop vomiting. This may be related to tobacco and alcohol, or it may be related to the body , dampness, , or even cold and dampness, etc. Therefore, there are many categories of phlegm, such as alcoholic phlegm, smoke phlegm, thick phlegm, foamy phlegm, rice soup phlegm, etc.
Friends around me often suffer from phlegm. For example, I have a friend who often gets stuck in phlegm. When talking to him, he often takes out a tissue and covers his mouth. There is also a friend who cleared his throat for a while, and once he cleared his throat again as soon as he passed by a new colleague. The new colleague was so sensitive that he thought his friend had a problem with him. Some friends do not start the day without spitting in the morning, some friends spit after eating, etc.
Coltsfoot that is compatible with Platycodon licorice, Polygala comes for this purpose,
consists of Chinese patent medicine Platycodon winter flower tablets :

Platycodon, Polygala (made), coltsfoot, and licorice.
treats cough with excessive phlegm and no obvious cold or heat. bronchitis is also included.
Although coltsfoot is not very famous, it can be used for all kinds of coughs. In the past two years, it was selected into the famous prescription Qingfei Paidu Decoction. It is an herb from the Asteraceae family. The flower buds and inflorescences used for medicinal purposes are grown from underground rhizomes that travel horizontally in winter and have first-class frost resistance.
has the properties of sweet, tonic and pungent, with mild warming and unblocking properties. It specifically enters the lung meridian and can lower qi, allowing the stagnant qi in the lungs to descend, and clearing out blood stasis in the lungs, thereby relieving coughs and asthma.
When the lungs are deficient, they become an organ for storing phlegm, so butterbur has the ability to relieve cough and asthma, and it also has the function of removing phlegm from the lungs. Regardless of whether the phlegm is thick or smelly, using it is like using a broom to sweep the floor. It is very appropriate and is a very popular flower for the lungs.
Coltsfoot and Platycodon licorice meet. Coltsfoot is more effective in relieving coughs, while Platycodon licorice is more effective in expelling pus and phlegm. The result is a happy one, with less coughing and less turbid phlegm.

Why is it said that there is less cough and less phlegm and turbidity, but not that it disappears? This is because this prescription treats various conditions where phlegm cannot be exhausted.
There is a kind of phlegm that lies in the heart and blocks the heart orifices. When it attacks, it causes epileptic convulsions and foaming phlegm at the mouth. This requires a dispersing medicine, which can not only relieve the orifices, but also enter the lungs and expel the phlegm. This is Polygala.
Polygala Polygala is bitter, pungent and slightly warm. In addition to entering the heart and lungs, it also enters the kidneys. The heart fire descends into the kidneys, which helps to open the mind. In addition, after lung qi enters the body, it needs to enter the kidneys to complete the circulation. Polygala can connect the lungs and kidneys.
Therefore, Polygala in this aspect is like the central words of an article, which can have a deepening effect. Because of this, in addition to its well-known effects of calming the nerves and improving intelligence, polygala root also has the ability to disperse phlegm and saliva and treat coughs with excessive phlegm.
The combination of four flavors is a perfect combination for relieving cough and eliminating phlegm. No wonder it can be used to treat various types of phlegm. Since people with long-term cough or phlegm usually do not have special symptoms of cold and heat, this prescription is more suitable for people with no obvious symptoms of cold and heat. However, since Polygala and winter flowers in this recipe are both pungent and warm, they can also be used to relieve cough and eliminate phlegm in cases of colds and colds with excessive phlegm.
