1. Source and History of Formula

1. Origin Background

Chai Ge Jie Ji Tang originated from the accumulation of traditional Chinese medicine classic theories and practical experiences. In ancient times, when people faced the invasion of exogenous diseases, they continuously explored effective treatment methods. With the in-depth understanding of diseases and the enrichment of drug applications, various formulas gradually took shape. Chai Ge Jie Ji Tang emerged under such circumstances. It is mainly designed for the situation where exogenous pathogenic factors invade the body surface of the human body, triggering a series of symptoms.

2. Historical Evolution

Chai Ge Jie Ji Tang can be traced back to 'Six Books on Cold Damage' written by Tao Hua in the Ming Dynasty. On the basis of inheriting the experiences of predecessors and combining his own clinical practice, Tao Hua carefully created this formula. Its original intention was to better treat the syndrome of the Yangming meridian of cold damage, and it played an important role in relieving the symptoms of exogenous febrile diseases at that time. As time passed, later medical experts continuously studied and applied Chai Ge Jie Ji Tang, adjusted and improved the formula according to the actual clinical situation, making its application in the treatment of exogenous diseases more extensive and accurate.

III. Pathogenesis, Effects and Treatments

1. Pathogenesis

Chai Ge Jie Ji Tang The pathogenesis targeted by Chai Ge Jie Ji Tang is exogenous wind-cold pathogenic factors, which stagnate and transform into heat, invading the muscle surface. When the healthy qi of the human body is insufficient, exogenous wind-cold pathogenic factors take advantage of the deficiency to enter the body, the pathogenic factors linger on the muscle surface, the defensive qi is stagnated, and the healthy qi and pathogenic factors struggle, resulting in symptoms such as fever and aversion to cold, and thin white tongue coating. If the pathogenic factors further transform into heat in the interior, symptoms such as bitter taste in the mouth, dryness and pain in the throat, and dizziness will appear. At this time, the qi and blood in the muscle surface meridians are not smooth, leading to discomfort such as headache and body pain.

2. Effects

Chai Ge Jie Ji Tang has the effect of relieving muscle and clearing heat. By using drugs such as Bupleurum chinense and Pueraria lobata to disperse pathogenic factors on the muscle surface, and drugs such as Scutellaria baicalensis to clear heat in the interior, the pathogenic factors on the surface can be resolved, and the heat in the interior can be cleared, so as to achieve the purpose of relieving both the exterior and the interior. At the same time, the drugs in the formula can also regulate nutrient qi and defensive qi, relieve pain, strengthen the healthy qi of the human body, and contribute to the recovery of the disease.

3. Treatments

Chai Ge Jie Ji Tang is mainly used to treat exogenous wind-cold syndrome transformed into heat. Common symptoms include gradually milder aversion to cold, increasing fever, absence of sweating, headache, eye pain, nasal dryness, restlessness and insomnia, dry throat, deafness, orbital pain, thin yellow tongue coating, floating and slightly rapid pulse, etc. These symptoms reflect the manifestations of exogenous pathogenic factors in the muscle surface and interior heat. Chai Ge Jie Ji Tang can effectively treat these symptoms and relieve the condition.

4. Analysis of Formula's Meaning

1. Synergy of Relieving Exterior & Clearing Heat

Bupleurum and Pueraria are good at inducing sweating to relieve the exterior syndrome, capable of dispersing wind-cold pathogenic factors in the muscle surface, allowing the pathogenic factors to find an outlet.

5. Comparison with Other Similar Formulas

1. Comparison with Yinqiao Powder

Yin Qiao San It is mainly used to treat the syndrome of exogenous wind-heat, with the main functions of clearing heat and detoxifying, and dispersing wind-heat. Its drug composition is mostly cold-natured herbs, such as honeysuckle flower, forsythia, etc. While Chai Ge Jie Ji Tang is mainly aimed at the syndrome of exogenous wind-cold transforming into heat, with equal emphasis on relieving the exterior and clearing heat. The drugs are relatively mild, including both herbs for dispersing wind-cold and herbs for clearing interior heat. There are obvious differences between it and Yinqiao San in terms of pathogenesis, efficacy and drug composition.

2. Comparison with Mahuang Decoction

Mahuang Tang is a pungent-warm exterior-relieving formula, mainly used to treat the exterior excess syndrome of exogenous wind-cold, with the main functions of inducing sweating to relieve the exterior and dispersing lung qi to relieve asthma. Its drug composition is mainly pungent-warm sweating herbs such as mahuang and cinnamon twig. Although Chai Ge Jie Ji Tang also has the effect of relieving the exterior, it is not simply pungent-warm sweating. Instead, it pays attention to clearing interior heat while relieving the exterior, and is applicable to the situation of exogenous wind-cold transforming into heat, which is different from Mahuang Tang in terms of applicable syndrome types and medication characteristics.
