Large Intestine collapse

Point Combination Rationale

The core strategy pairs Front-Mu and Back-Shu points of the Large Intestine (Tianshu ST-25 and Dachangshu BL-25) to regulate its function from both front and back. Shangjuxu ST-37 as the Lower He-Sea point of the Large Intestine adds specificity. Zusanli ST-36 tonifies the Spleen and Stomach to address the root deficiency. Baihui GV-20 and Changqiang GV-1 form a top-to-bottom axis along the Governing Vessel specifically for lifting sunken Qi and treating prolapse.

Technique Recommendations

Moxibustion is essential for this pattern and should be used on most points, particularly Guanyuan REN-4, Shenque REN-8 (indirect moxa with salt or ginger slice only), Zusanli ST-36, and Baihui GV-20. The warming nature of moxa directly addresses the Cold deficiency at the pattern's root. Reinforcing needle technique should be used throughout. For Baihui GV-20, subcutaneous insertion directed posteriorly with moxa cone on the handle is a classical approach for prolapse.

Additional Points

Shenque REN-8 (navel): salt-separated moxibustion here powerfully warms the Spleen Yang and is a classical emergency technique for severe collapse. Pishu BL-20 and Shenshu BL-23 (Back-Shu points of Spleen and Kidney) can be added to address the root organ deficiencies. Chengshan BL-57 is empirically effective for rectal prolapse and hemorrhoids. For the Ba Liao points (BL-31 through BL-34), electroacupuncture can be applied to directly stimulate the sacral nerves that innervate the pelvic floor muscles.

Confirm that pathogenic residue is cleared before astringent therapy

The most critical clinical decision with this pattern is confirming that no residual Damp-Heat, food stagnation, or toxic pathogen remains in the intestines before using astringent and binding herbs. Premature use of formulas like Zhen Ren Yang Zang Tang when active pathogens are still present is a classic error that traps the pathogen inside, potentially causing dangerous deterioration. Look carefully for absence of foul-smelling stools, absence of burning or tenesmus, and absence of yellow greasy tongue coating before prescribing astringent formulas.

Distinguish the dominant root: Spleen Qi sinking vs. Kidney Yang deficiency

When fatigue, poor appetite, and prolapse dominate with less prominent cold signs, the primary root is Spleen Qi deficiency with sinking, and Bu Zhong Yi Qi Tang is more appropriate. When dawn diarrhea, cold limbs, sore lower back, and deep cold dominate, Kidney Yang deficiency is the primary root, and Si Shen Wan or formulas with Fu Zi and Rou Gui are more appropriate. Many cases involve both, requiring combined approaches.

Moxibustion is often more effective than needling alone

Given the Cold-deficiency nature of this pattern, moxibustion is arguably more important than needling. Salt-separated moxa at Shenque REN-8, ginger-separated moxa at Guanyuan REN-4, and direct small-cone moxa at Baihui GV-20 are classical techniques that clinicians should not overlook. These warming methods directly introduce Yang Qi and have a faster clinical response for Cold-deficiency diarrhea than needling alone.

Pulse and tongue subtleties

The pulse may vary between deep-slow-thin (Kidney Yang dominant) and soft-weak-moderate (Spleen Qi dominant). A pulse that is both deep and forceless at the chi position strongly suggests Kidney involvement. The tongue in pure intestinal collapse should be pale, possibly swollen with teeth marks, with thin white coating. If the coating becomes yellow or greasy, suspect residual pathogen and reconsider the treatment approach before continuing with astringent therapy.
