This study conducted frequency statistics on the five elements and six qi formulas in Chen Wuzhi’s "Three Causes, One Extreme Disease Syndrome Formula". The top 10 specific drugs were roasted licorice, Pinellia ternata, papaya, ginger, Poria cocos, aconite, dried ginger, Achyranthes bidentata, Qingpi, and cooked Rehmannia glutinosa. The commonly used high-frequency drugs had the effect of tonifying the spleen and stomach, and the meridians were mainly attributed to the lung and spleen meridians. The pathogenesis analysis was often attributed to the "epidemic enters from the mouth and nose", There are many lung symptoms that enter from the mouth and nose in "Treatise on Febrile Diseases" [
5], such as "nasal tingling and retching" in Guizhi Tang and "wheezing without sweat" in Mahuang Tang. In addition, it also reflects Chen Wuxuan’s academic thought that "stomach is the fundamental part of the human body".
According to the statistics of drug properties, Chen prefers to use warm drugs, followed by mild and mild drugs. Chen is accustomed to using spicy and dry drugs based on differentiation of symptoms and signs. He always maintains a cautious attitude towards prescriptions and never adheres to habits. Shengsanzi "is a famous formula composed of warm and hot drugs used to treat cold and epidemic diseases. The five flavors are the most sweet, followed by the pungent and bitter flavors. The "San Yin Fang" has a saying: "When it comes to treating and transforming, people should also respond to it... Those who become ill with the deficiency and excess of their organs are called Qi of the time." Its medicinal taste is often taken from the pungent sweetness to "turn pungent sweetness into yang", and sweet flavored medicines are used to supplement and harmonize various medicines. Bitter can dry, diarrhea can be strong, and the astringent, spicy, and warm flavors can be restrained to make up for the deficiency. It has the beauty of complementing each other. He drew on clinical experience and added drugs to the original formula, We have created the "Nourishing Stomach Soup" that "warms the stomach and reduces phlegm, and eats healthy qi". An important factor is the geographical environment. Wenzhou is located near the mountains and the sea, and is humid all year round. Dampness is particularly common, so it is not afraid of dryness and is suitable for the application of calming stomach powder, regulating qi powder, and nourishing stomach soup, which are also consistent with its concept of "adapting to local conditions" [
10].
According to the ranking of confidence, it was found that the most common ingredients were roasted licorice combined with Pinellia ternata and peony, and Achyranthes bidentata combined with papaya. Roasted licorice, Pinellia ternata regulate qi and stomach, Achyranthes bidentata and papaya dry dampness and phlegm, and also supplement deficiency. After clustering analysis of traditional Chinese medicine, it can be concluded that the first group is ginger, white peony, aconite, papaya, and achyranthes bidentata, while the second group is roasted licorice, poria cocos, dried ginger, pinellia ternata, and green peel. The first group is the Wen Yang Jian Pi Li Shui group, the Jian Pi Li Shui group, which covers the spleen and likes dryness and dampness, and spleen deficiency is prone to dampness. Therefore, Jian Pi Li Shi is a commonly used treatment for spleen deficiency. The second group is the Jian Pi and Wei group, which covers the spleen and promotes clear qi, and the stomach qi is reduced to flat. If the spleen and stomach are not in harmony, it is easy to generate turbid qi. Therefore, Jian Pi and Wei are the methods for consolidating and protecting the body’s positive qi.
These 16 prescriptions are collectively referred to as the San Yin Si Tian Fang, which are representatives of traditional Chinese medicine’s luck prescriptions. [
11] Each of the 10 "Five Yun Prescriptions" is based on its age and luck, and is blended with the five flavors. The prescription is regular, the concept is exquisite, the formula is simple and the medicine is regular, and the duration is average. (See Table 9) There are also 6 "Six Qi Seasons for the Diagnosis and Treatment of Civil Diseases", designed for the annual changes in the Qi (Sui Qi) of the Si Tian, namely: Chenxu Year Jingshun Tang, Maoyou Year Shenping Tang, Yinshen Year Shengming Tang, Ugwei Year Beihua Tang, Ziwu Year Zhengyang Tang, and Sihai Year Fuhe Tang. Each prescription has its own additions and deletions. The 16 prescriptions are characterized by a preference for Xin Gan Wen and a focus on regulating the spleen and stomach, which may be related to the common use of mature prescriptions by doctors in the Song Dynasty to treat diseases, with a preference for warming and dryness [
12]. The Qing Dynasty physician Miao Wen [
13] compiled and annotated these 16 prescriptions into the "San Yin Si Tian Fang" for publication, and Wang Xugao [
14] compiled the "Qi Zheng Zhi Ge Jue" based on the 16 prescriptions, all of which reflect the ancient physicians’ emphasis on the San Yin Si Tian Fang. Nowadays, many doctors have begun to pay attention to the clinical value of the five movements and six qi, and have applied them to clinical practice. Gu Zhishan [
15] flexibly applied the three factor method and achieved satisfactory results. However, it should also be noted that these formulas generally tend to be spicy, sweet, and warm in terms of medication. Therefore, in specific clinical practice, treatment should be based on differentiation of symptoms and signs, and adherence to ancient formulas should be avoided without being flexible.
