Key points of diagnosis
Mai Men Dong Tang is a prescription commonly used to treat insufficient yin fluid in the lungs and stomach, which causes the qi to flow upward and trigger coughing or vomiting. When the yin fluid in the lungs and stomach is insufficient, the qi in the body will flow upward, causing symptoms such as coughing, shortness of breath, and wheezing.
In clinical practice, Mai Men Dong Tang is mainly used for patients with cough and spitting, shortness of breath and wheezing, or dry mouth and vomiting. These patients usually have a dry and red tongue with little coating and a weak pulse.
These symptoms indicate that the body's yin fluid is insufficient and the qi is rising. Treatment is needed by clearing the lungs and stomach and lowering the qi. Maimonide decoction is designed to target these symptoms and can effectively relieve these discomforts.
Effects and indications of Mai Men Dong Tang
effect
The main effect of Mai Men Dong Tang is to nourish the lungs and stomach, and to reduce adverse qi. It targets deficiency-heat lung consumptive disease and stomach yin deficiency caused by deficiency of lung and stomach yin.
Indications
Deficiency-heat pulmonary emphysema : The main symptoms include cough and wheezing, sore throat, uncomfortable expectoration or spitting saliva, dry mouth and throat, hot hands and feet, red tongue with little coating, and weak and rapid pulse.
Stomach Yin Deficiency Syndrome : The main symptoms include vomiting, poor appetite, hiccups, thirst and dry throat, red tongue with little coating, and weak and rapid pulse.
Pathogenesis Analysis
Maimondong decoction is mainly used to treat a condition called deficiency-heat lung atrophy, which is caused by insufficient yin fluid in the lungs and stomach, resulting in the upward reversal of qi and fire. Although the symptoms appear in the lungs, the actual source of the problem lies in the stomach.
The stomach is responsible for producing body fluids. If the stomach's body fluids are insufficient, the lung's body fluids will also decrease, eventually leading to a situation where both the lungs and stomach are deficient in yin fluids.
When the lungs and stomach are deficient in yin fluid, the virtual fire in the body will burn the body fluids and form phlegm, causing the lungs to lose their normal function of clearing the interior, resulting in symptoms such as coughing, qi reversal, and spitting saliva.
The throat is the gateway to the lungs and stomach. When the yin fluid of the lungs and stomach is damaged, the body fluid cannot go up to moisten the throat, resulting in dry mouth and dry throat. In addition, excessive internal heat can make people feel hot in the hands and feet. If the yin fluid of the stomach is insufficient, the function of the stomach will be disordered, causing qi to go up and trigger vomiting. A red tongue with little coating and a weak pulse are all manifestations of insufficient yin fluid and excessive internal heat.
Therefore, the key to treating this disease is to clear the yin fluid of the lungs and stomach, and to lower the adverse Qi so that the Qi and fire no longer rise up, thereby achieving the therapeutic effect.
Modern Pharmacology Research
In modern medicine, Mai Men Dong Tang is widely used to treat a variety of diseases. The following are some common application areas:
Respiratory diseases: Mai Men Dong Tang is often used to treat chronic bronchitis, bronchiectasis and chronic pharyngitis. These diseases are usually accompanied by symptoms such as cough, shortness of breath and wheezing. Maimonopsis soup can effectively clear the lungs and stomach, reduce adverse qi and relieve these discomforts.
Occupational diseases and infectious diseases: Maimendong decoction can also play a role in occupational diseases and infectious diseases such as silicosis and tuberculosis. These diseases often lead to insufficient yin fluid in the lungs, causing symptoms such as coughing and qi reversal. Maimendong decoction helps patients recover their health by nourishing the lungs and stomach.
Digestive system diseases: Mai Men Dong Tang is also effective for digestive system diseases such as gastric and duodenal ulcers, chronic atrophic gastritis and pregnancy vomiting. These diseases are usually accompanied by insufficient stomach yin, leading to symptoms such as vomiting, thirst, and dry throat. Maimonopsis soup can nourish stomach yin, reduce adverse reactions and stop vomiting.
Other applications: Modern research has also found that Mai Men Dong Tang has a variety of effects, such as lowering blood sugar, antitussive, anti-allergic and promoting saliva secretion. For example, studies have shown that Ophiopogon japonicus soup has a blood sugar-lowering effect on alloxan diabetic mice, and the effect is more obvious under fasting conditions.
In addition, the antitussive effect of Ophiopogon japonicus decoction is mainly related to inhibiting the production and release of inflammatory cough-inducing transmitters, and has a significant effect on cough caused by respiratory inflammation. Ophiopogon japonicus decoction can also inhibit degranulation and histamine release, has anti-allergic effects, and can promote saliva secretion. It has a significant effect on healthy people, bronchitis patients and patients with Sjögren's syndrome.
Diet therapy combined with adjunctive therapy
When using Mai Men Dong Tang for treatment, taking appropriate diet therapy can enhance the efficacy. Mai Men Dong and Tremella Soup : Tremella and crystal sugar boiled soup has the effect of nourishing yin and moistening the lungs, nourishing the stomach and producing body fluids, and is suitable for people with lung and stomach yin deficiency.
First, prepare the ingredients: 30 grams of Tremella and an appropriate amount of rock sugar. Soak the Tremella in clean water for about 2 hours in advance until it becomes soft, then tear it into small pieces. Put the soaked Tremella into the pot and add about four cups of clean water. Then, add a few slices of washed Ophiopogon japonicus to add fragrance and nourishing effect to the soup.
Place the pot on the stove, bring to a boil, then simmer for about 30 minutes to allow the essence of Tremella and Ophiopogon japonicus to be fully released. Finally, add appropriate amount of rock sugar according to personal taste, stir evenly, and continue to cook for about 5 minutes until the rock sugar is completely dissolved. This soup not only tastes smooth, but also moisturizes the lungs and clears dryness, making it suitable for daily drinking.
