Heqile (Roasted) 10 pieces.
The above single herb is ground into powder, mixed with rice gruel, and taken in one dose.

[Collected Explanations]
Li □ stated: Qi li (flatus accompanied by diarrhea) refers to diarrhea with flatus due to qi deficiency sinking, leading to sliding and incontinence. Heqile has astringent properties and can warm the stomach and secure the intestines. Mixing with rice gruel utilizes the grain's qi to assist the stomach qi. Taking it in one dose ensures the medicinal flavor enters together, exerting greater force.
You Yi stated: Qi li refers to the simultaneous loss of qi and stool. Heqile secures the intestines and regulates qi; rice gruel stabilizes the middle and benefits the stomach and intestines. Taking it in one dose reflects the principle of "tonifying the lower and treating the lower" using an urgent method.

If there is diarrhea with a rapid pulse, slight fever, and sweating, the condition will heal spontaneously; if the pulse is tight, the pathogen has not yet resolved.

[Annotation]
Diarrhea with a rapid pulse indicates internal heat diarrhea. Slight fever and sweating indicate that the pathogenic factor has declined, so the condition will heal spontaneously. If the pulse is tight, it indicates that the exterior pathogen has not declined, thus the disease remains unresolved.

[Collected Annotations]
Cheng Lin stated: Cold causes diarrhea. If the pulse is rapid with slight fever, the interior cold has departed; sweating harmonizes the exterior qi. With both interior and exterior harmonized, the condition heals spontaneously. If the pulse becomes tight again, it is known that the cold pathogen remains, indicating the disease is unresolved.

In cases of diarrhea with slight fever and thirst, and a weak pulse, the condition will heal spontaneously.

[Annotation]
Diarrhea with high fever and thirst indicates excess pathogen; a weak pulse indicates deficient healthy qi, which cannot recover on its own. Now, with slight fever and thirst and a weak pulse, both pathogen and healthy qi have declined, so it is known that the condition will heal spontaneously.

[Collected Annotations]
Cheng Lin stated: Diarrhea with high fever and thirst leans toward Yang syndrome; no fever and no thirst lean toward Yin syndrome; neither can heal spontaneously. Slight fever with thirst indicates harmony of Yin and Yang; a weak pulse indicates the departure of pathogenic qi, hence immediate spontaneous healing.

In cases of diarrhea with a rapid pulse and thirst, the condition will heal spontaneously; if it does not improve, pus and blood must appear in the stool, because of the presence of heat pathogen.

[Annotation]
This follows the meaning of the previous clause where both pathogen and healthy qi decline and the disease should heal spontaneously but does not. If it does not improve, the exterior harmonizes, heat recedes, but the pulse remains rapid with thirst, indicating interior heat remains unremoved, hence purging pus and blood.

[Collected Annotations]
Wei Litong stated: In diarrhea, although surplus Yang qi is auspicious, it must not be excessive, lest it form heat pathogen injuring Yin, causing the risk of Yang resurgence with bias.

In cases of diarrhea, if the Cun pulse is unexpectedly floating and rapid, while the Chi pulse is naturally choppy, pus and blood must appear in the stool.

[Annotation]
This follows the meaning of the previous clause where interior and exterior are harmonized and the disease should heal spontaneously but does not. Diarrhea is an interior disease, yet a floating and rapid exterior pulse appears, hence it is said: "the pulse is unexpectedly floating and rapid." However, since the Chi pulse is naturally choppy, it is known that heat has sunk into the blood level, inevitably resulting in purging pus and blood.

[Collected Annotations]
Xu Bin stated: Diarrhea belongs to Cold; the pulse should be deep and slow. Unexpectedly floating and rapid indicates Yang superiority. The Chi pulse being naturally choppy indicates Yang pathogen entering Yin. This also results from excess heat, hence it is said: "must purge pus and blood."
Cheng Lin stated: Floating and rapid Cun pulse indicates excess heat; naturally choppy Chi pulse indicates blood deficiency. Due to excess heat, it accompanies heat to cause passage of pus and blood.

In cases of diarrhea, if the pulses at all three positions are equal, but pressing the epigastrium reveals hardness, urgent purgation is required, suitable for Dachengqi Tang (Major Order the Qi Decoction).

[Annotation]
For patients with diarrhea, if the epigastrium is obstructed, it belongs to the syndromes of various Xiexin Tangs (Drain the Epigastrium Decoctions). If the pulses at Cun, Guan, and Chi positions are all flat, solid, and forceful, despite diarrhea, one should attack the accumulation.

[Collected Annotations]
Li □ stated: In diarrhea, hardness upon pressing the epigastrium indicates excess. If the pulse were weak or faint, purgation would still be inadvisable. Now that the pulses at all three positions are flat, it is known that the interior qi is not deficient, and urgent purgation is naturally indicated. This is the method of diagnosing based on pulse and confirming with symptoms.
