Huo Xiang Zheng Qi Shui: Relieving Summer Dampness and Gastrointestinal Flu

SERVICE HONGJI MEDICAL

I. The Source and History of Huo Xiang Zheng Qi Shui

Huoxiang Zhengqi San is one of the classic prescriptions commonly used in clinical practice of traditional Chinese medicine, with a long history. It originated from the Taiping Huimin Heji Jufang officially promulgated in the Song Dynasty. This prescription book is the first official compiled patent medicine pharmacopoeia in the history of our country, and has had a profound impact on the development of later prescription science.

Huoxiang Zhengqi San was initially formulated to treat cholera with vomiting and diarrhea caused by external contraction of summer heat and dampness and internal injury by raw and cold foods. In ancient times, people's adaptability to the natural environment was relatively weak. During the summer and damp seasons, the climate was hot and humid, and people were prone to contracting summer heat and dampness pathogens. At the same time, due to indulging in cold drinks and foods, the yang qi of the spleen and stomach was damaged, resulting in disharmony of the spleen and stomach functions, presenting a series of symptoms such as aversion to cold and fever, headache, fullness and stuffiness in the chest and diaphragm, pain in the abdomen, nausea and vomiting, borborygmus and diarrhea.

Huoxiang Zhengqi San is an effective traditional Chinese medicine prescription created for these symptoms. After being passed down for thousands of years, it has been continuously applied to this day and has become a commonly used good prescription for treating such diseases.

III. Pathogenesis, Efficacy, and Treatment

1. Pathogenesis

Huoxiang Zhengqi Powder The pathogenesis it targets is mainly exogenous wind-damp pathogen and internal injury by raw and cold foods, leading to disharmony of the spleen and stomach functions. In summer, wind-damp is prevalent, and the human body is vulnerable to the invasion of wind-damp pathogen. At the same time, if excessive consumption of raw and cold foods damages the yang qi of the spleen and stomach, the transportation and transformation of the spleen and stomach are abnormal, endogenous damp turbidity is generated, and the internal and external damp pathogens collude with each other, blocking qi movement, thus triggering a series of diseases.

2. Efficacy

Huoxiang Zhengqi Powder has the effects of relieving the exterior syndrome, resolving dampness, regulating qi and harmonizing the middle jiao. In the formula, Herba Pogostemonis relieves the exterior syndrome, resolves dampness, regulates qi and harmonizes the middle jiao, and is the main herb; Folium Perillae and Radix Angelicae Dahuricae relieve the exterior syndrome and dispel cold, assisting Herba Pogostemonis to disperse the exterior pathogen externally; Atractylodes macrocephala, Tangerine peel, Pinellia ternata, Magnolia officinalis, Poria cocos, etc. dry dampness and promote the function of the spleen, promote qi movement and regulate the stomach to eliminate internal dampness; Platycodon grandiflorum disperses the lung qi and benefits the throat, Licorice root, Chinese date and Fresh ginger harmonize the properties of the herbs. All the herbs are used together to achieve the effects of relieving the exterior syndrome, resolving dampness, regulating qi and harmonizing the middle jiao.

3. Treatment

It is mainly used to treat the syndrome of exogenous wind-cold and internal injury by dampness stagnation. Symptoms include aversion to cold and fever, headache, chest and diaphragm fullness and oppression, abdominal pain, nausea and vomiting, borborygmus and diarrhea, etc. In addition, in modern clinical practice, Huoxiang Zhengqi Powder is also commonly used to treat various diseases such as gastrointestinal cold, acute gastroenteritis, heat stroke, etc. As long as it conforms to the pathogenesis characteristics of exogenous wind-damp and internal injury by raw and cold foods, it can be applied.

IV. Analysis of the Formula's Significance

1. Combining Exterior-Resolving and Dampness-Transforming

In the formula, Herba Pogostemonis, Folium Perillae, Radix Angelicae Dahuricae relieve exterior cold and can quickly disperse the pathogenic factors on the body surface. At the same time, drugs such as Herba Pogostemonis, Rhizoma Atractylodis Macrocephalae, Pericarpium Citri Reticulatae, Rhizoma Pinelliae, Cortex Magnoliae Officinalis, Poria can aromatically transform dampness and dry dampness to promote the function of the spleen, so as to resolve the internal and external damp pathogens. The combination of relieving the exterior and transforming dampness can not only relieve the exterior syndrome of exogenous pathogens but also eliminate the damp pathogens of internal injury, making the pathogens on the exterior and interior disappear and restoring the normal physiological functions of the human body.

2. Balancing Qi-Regulating and Center-Harmonizing

Drugs such as Pericarpium Citri Reticulatae, Cortex Magnoliae Officinalis, Pericarpium Arecae regulate qi to relieve distension, promote qi movement to stop pain, and can effectively relieve qi stagnation symptoms such as abdominal distension, fullness, and pain. Rhizoma Atractylodis Macrocephalae, Poria, Radix Glycyrrhizae, Fructus Jujubae invigorate the spleen and harmonize the stomach, regulating the qi mechanism of the middle jiao spleen and stomach. Regulating qi and harmonizing the middle jiao complement each other, making the functions of the spleen and stomach return to normal, the qi mechanism smooth, and thus eliminating symptoms such as nausea, vomiting, diarrhea, etc.

3. Combining Ascending and Descending

Platycodon grandiflorum promotes the lung qi and benefits the membranes, which can make the lung qi smooth, contributing to relieving the exterior and regulating the qi mechanism, reflecting the method of lifting the kettle lid to uncover, enabling the lung qi to be diffused, the upper jiao to be unobstructed, the body fluids to descend, and the water passages to be regulated, so that the damp pathogens have an outlet. At the same time, Pericarpium Arecae promotes qi movement to relieve distension, promotes diuresis and reduces swelling, making the damp pathogens go out through urine. There is both descent and ascent, jointly regulating the qi mechanism and water metabolism of the human body.
