Commentary: The herbs used in the above three formulas belong to the Taiyin and Yangming meridians.

Respectful Note: Ancient formulas for treating Fan Wei (Regurgitation/Reverse Flow) mostly use aromatic, drying, and intensely hot herbs, which are not suitable as standard practice. Here, only one or two are retained for reference. Regarding Zhu Danxi's mention of herbs that nourish blood, benefit yin, moisten dryness, harmonize the Stomach, and regulate the middle, although specific formulas are not provided, they should be selected according to the pattern. Observing his theoretical stance already covers more than half of the matter.

Miscellaneous Formulas
Shao Zhen Wan (Burned Needle Pill)
(See the Children's Section for the formula)

The *Zhen Jing* (Classic of Acupuncture) states: All cases of Zhang (Distension) occur outside the Zang-Fu organs, pushing against them and expanding the chest and hypochondrium, causing the skin to swell; hence it is named "Zhang". It may also arise from Jue Qi (Rebellious Qi) accumulating below, where Ying and Wei (Nutritive and Defensive Qi) stagnate and stop, cold qi rebels upward, and true pathogenic factors attack each other. When these two qi interact and combine, Zhang (Distension) is formed.

Commentary: The discussion details the various syndromes of distension arising from the five Zang and six Fu organs; it is advisable to study the original text carefully.

The *Nei Jing* (Inner Canon) states: Various abdominal distensions and enlargements all belong to Heat. If there is abdominal fullness, distension obstructing the diaphragm, and Jue Qi rising from the hypochondrium to invade upwards, this belongs to Cold-Dampness stagnation in the Taiyin and Yangming meridians.

The *Yuan Bing Shi* (Book on the Origin of Diseases) states: Abdominal distension and enlargement, sounding like a drum when tapped, occurs because Qi belongs to Yang, and Yang transforms into heat. When heat is extreme, such manifestations occur.
