Herbs 6 Rebellious Qi Downward

定喘湯 (Dìng Chuǎn Tāng) - Arrest Wheezing Decoction
6 factoids

(1) "Everything enters LU. Unlike Su Zi Jiang Qi Tang, which hints at Kidney involvement with Rou Gui, this formula is pure Lung. No other organs need to be considered ."

(2) "Ma Huang Tang shadow, not full Ma Huang Tang. Gui Zhi is absent, so the exterior-releasing action is minimized. The focus is on internal regulation, not sweating out a pathogen ."

"Two cold herbs mean real heat. (3) Sang Bai Pi and Huang Qin aren't there for show—they indicate that phlegm-heat has formed. The sputum is thick and yellow, not thin and white ."
(4) "Bai Guo is the unique element. Its astringent quality prevents the dispersing herbs from scattering Lung Qi. It ""holds"" while the formula opens and descends " (6) Acrid count is lower than Su Zi Jiang Qi Tang. Only four acrid herbs (Ma Huang, Zi Su Zi, Kuan Dong Hua, Ban Xia) compared to the previous formula's all-acrid-warm profile. This reflects the shift from pure cold to (5) mixed heat-cold pathology ."
Exterior signs may persist. Even without Gui Zhi, the Ma Huang core can still address lingering fever and chills if present .

""The cold has turned to heat, the phlegm is thick, and the Lungs need both opening and cooling to restore order."""

丁香柿蒂湯 (Dīng Xiāng Shì Dì Tāng) - Clove and Persimmon Calyx Decoction

(1) Exclusively for hiccup. This is the specific formula for this specific complaint. When you see hiccup, you think of this formula . (2) No cold herbs. Ding Xiang (warm), Ren Shen (slightly warm), Sheng Jiang (warm). Only Shi Di is neutral. This tells you the pattern is cold, not heat ." (3) Shi Di's astringent quality is key. The unripe persimmon's ""paint in the mouth"" sensation is astringency—it binds rebellious Qi and pulls it down ." (4) Mild Qi deficiency is assumed. Ren Shen (or Dang Shen) supports the Middle so Qi can stay down. The deficiency is subtle—just enough that the Qi lacks anchoring ."
Channel entry is LU, SP, ST. (5) Hiccup involves both the Stomach (digestive) and diaphragm (respiratory)—the formula addresses both ." Warm the Middle, move Qi down. The strategy is simple and direct. No complex heat-clearing, no deep Kidney tonification—just warmth and descent ."

橘皮竹茹湯 (Jú Pí Zhú Rú Tāng) - Tangerine Peel and Bamboo Shavings Decoction

(1) Ju Pi + Zhu Ru = warm-cool balance. Ju Pi moves Qi (warm), Zhu Ru clears Stomach heat (cool). Together they harmonize the Middle regardless of temperature predominance ."

Zhu Ru is unique. It specifically cools Stomach heat—not Lung, not Heart, not general heat. This is why it's the ""sage herb"" for heat-type vomiting ."

The 3 Pals are included. Gan Cao, Da Zao, Sheng Jiang—the harmonizing trio from GZT—provide foundation and protection .

Same structure as XCHT. Ren Shen, Sheng Jiang, Da Zao, Gan Cao"

Extension of Ding Xiang Shi Di Tang. Same channels (LU, SP, ST), same purpose (stop rebellious Qi), (2) but with cooling capacity added .

(3) Intensity is slightly more. More herbs, more complex, more Qi support—for when the condition is a bit more stubborn or the deficiency more pronounced ."

Don't fixate on tongue/pulse. The textbook says the tongue/pulse indicators aren't required, and Pai agrees—the symptom (hiccup/nausea) is the guide ."

Clinical pearl: When you see a patient with hiccup or nausea—especially if they've been ill, are weak, and you can't tell if it's cold or heat (or it's both)—think of Ju Pi Zhu Ru Tang. It's the ""balanced"" option that covers both bases while supporting the Qi that makes regulation possible ."

旋覆代赭湯 (Xuán Fù Dài Zhě Tāng) - Inula and Hematite Decoction

First formula in Pai's life. His teacher prescribed it for his burping in Shang Han Lun class. It works .

Xuan Fu Hua is unique. Most flowers ascend; this one descends. It directs phlegm and rebellious Qi down .

Dai Zhe Shi weighs down. A heavy mineral that physically pulls rebellious Qi down. Its coldness balances the warm herbs .

Strongest of the three. Ding Xiang Shi Di Tang (mildest), Ju Pi Zhu Ru Tang (middle), Xuan Fu Dai Zhe Tang (strongest) .

Family resemblance to XCHT. Replace Chai Hu/Huang Qin with Xuan Fu Hua/Dai Zhe Shi, and you get this formula. Same structure, different target ."

Can address both digestion and respiration. Despite the textbook's emphasis on Middle Jiao, Xuan Fu Hua's Lung affinity means this formula can also address respiratory issues with phlegm and rebellion ."

Clinical pearl: When you see a patient with severe, unremitting belching or hiccup, especially if they have a hard, distended feeling in the epigastrium and a history of mistreated illness or chronic Stomach weakness, think of Xuan Fu Dai Zhe Tang. It's the heavy artillery when the gentler belching formulas aren't enough ."

蘇子降氣湯 (Sū Zǐ Jiàng Qì Tāng) - Perilla Fruit Decoction for Directing Qi Downward

5 facts

Rebellious Qi is the key. When Qi moves upward against its proper direction, you get coughing, wheezing, vomiting, belching.This formula directs it back down ."

Why Rou Gui?"" The presence of (1) Rou Gui tells you this isn't just a Lung issue—the Kidneys aren't grasping the Qi. Warming the source allows the Kidneys to anchor what the Lungs send down ."

(2) Er Chen Tang minus Fu Ling. Ban Xia, Chen Pi, and Gan Cao transform phlegm, but Fu Ling is omitted because its draining action would pull Qi down in a different way—here we need directed descent, not drainage ."

(3) Dang Gui addresses blood stagnation. When Qi rebels, blood doesn't flow smoothly. Dang Gui isn't treating a ""blood issue""—it's ensuring blood moves with corrected Qi ."

(4) Hou Po is distinctive. Its strong Qi-moving action in the chest and abdomen is what sets this formula apart from others .

The ""below"" symptoms are potential, not primary. Lower back pain, edema, fatigue—these suggest Kidney deficiency but may not be the chief complaint. Pain threshold varies too much to use as a severity indicator ."

Often follows unresolved wind-cold. The phlegm-cold is a (5) sequela of an exterior invasion that wasn't fully resolved .

Clinical pearl: When you see a patient with chronic cough and wheezing, especially if inhalation is more labored than exhalation (suggesting Kidney not grasping), with cold-type sputum (watery, white), and maybe some lower back weakness—think of Su Zi Jiang Qi Tang. It's the formula that says: "The Qi is flying upward because nothing is holding it down. Warm the source, direct the excess, and restore order."""
