About This Formula*
Traditional Chinese Medicine background and properties
Formula Description*
A classical formula for persistent belching, hiccups, nausea, or a sensation of fullness and hardness in the upper abdomen. It works by calming upward-surging Qi in the Stomach, dissolving phlegm, and gently strengthening the digestive system. Originally designed for digestive disturbances arising after illness, it remains one of the most widely used formulas for stubborn reflux and belching.

TCM Patterns*
In TCM, symptoms don't appear randomly — they cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Xuan Fu Dai Zhe Tang is traditionally associated with these specific patterns.
The following describes this formula's classification within Traditional Chinese Medicine theory and is provided for educational purposes only.
Why Xuan Fu Dai Zhe Tang addresses this pattern
This is the primary pattern the formula was designed for. When the Stomach is weakened (often after illness or improper treatment), it loses its natural ability to send Qi downward. This failure allows Qi to rebel upward, producing persistent belching and hiccups. Simultaneously, the weak Stomach and Spleen can no longer properly transform fluids, leading to the accumulation of phlegm that blocks the middle burner and causes the characteristic sensation of hardness below the heart. Xuan Fu Dai Zhe Tang addresses every facet of this pattern: Xuan Fu Hua and Dai Zhe Shi redirect the rebellious Qi downward, Ban Xia and Sheng Jiang dissolve phlegm and scatter fluid accumulation, and Ren Shen, Zhi Gan Cao, and Da Zao rebuild the deficient Spleen and Stomach Qi at the root of the problem.
A practitioner would look for one or more of these signs
Frequent, persistent belching that does not relieve the discomfort
Sensation of hardness and stuffiness below the heart (epigastric area)
Nausea with possible vomiting of clear watery fluid or phlegm
Stubborn hiccups that recur frequently
Reduced appetite due to Stomach weakness
Why Xuan Fu Dai Zhe Tang addresses this pattern
When the Spleen fails to transport fluids properly, pathological fluid and phlegm accumulate in the Stomach domain. This phlegm obstructs the Qi mechanism in the middle burner, causing a palpable sense of fullness and hardness below the heart, along with nausea and the regurgitation of watery or slimy fluid. The formula dissolves this phlegm through Ban Xia and Xuan Fu Hua, scatters the fluid accumulation with a heavy dose of Sheng Jiang, and uses Dai Zhe Shi to weigh down the turbid Qi that has been pushed upward by the phlegm obstruction.
A practitioner would look for one or more of these signs
Hard, stuffy feeling in the epigastrium
Vomiting of clear watery fluid or phlegm
Persistent nausea with a slippery tongue coating
Why Xuan Fu Dai Zhe Tang addresses this pattern
When the Liver's Qi becomes excessive or stagnant, it can 'invade' the Stomach (known as Wood overacting on Earth in five-phase theory). This disrupts the Stomach's descending function, causing belching, hiccups, and nausea. The rebellious upward energy from the Liver compounds the Stomach's weakness. Dai Zhe Shi is particularly important here because it specifically suppresses the upward surging of Liver Qi, while Xuan Fu Hua calms the Liver-Stomach axis. The formula's Qi-tonifying herbs prevent the Stomach from being further overwhelmed by the Liver's aggression.
A practitioner would look for one or more of these signs
Belching that worsens with emotional stress
Short, frequent hiccups with a wiry pulse
Epigastric distention with a subjective sense of upward pressure
How It Addresses the Root Cause*
This formula addresses a condition that typically arises after an illness has been treated with sweating, vomiting, or purging methods. Although the original illness resolves, these treatments can injure the Spleen and Stomach. When the middle burner (the digestive center) is weakened, two consequences follow: the Stomach loses its natural downward-directing function, and the Spleen can no longer properly transform and transport fluids, leading to the accumulation of Phlegm and thin mucus internally.
With the Stomach too weak to push Qi downward, Qi rebels upward instead. This upward-rebelling Qi, combined with Phlegm obstruction in the middle, produces the hallmark symptoms: a sensation of fullness and hardness in the upper abdomen (below the breastbone), persistent belching that brings no relief, nausea, possible vomiting, and hiccups. The tongue coating tends to be white and slippery (reflecting Phlegm and internal dampness), and the pulse is typically wiry yet weak (wiry from Qi stagnation and possible Liver overacting on a weak Stomach, and weak from underlying deficiency).
An important secondary factor is that when the Spleen/Stomach "Earth" system is weak, the Liver "Wood" system may take advantage and overact on it, a dynamic known as "Wood overacting on Earth" (木乘土). This Liver involvement can intensify the upward rebellion of Qi, worsening belching and hiccups. The formula must therefore address the root deficiency of the middle burner, transform accumulated Phlegm, and redirect the rebellious Qi firmly downward.
Formula Properties*
Slightly Warm
Predominantly pungent and sweet with a salty component: pungent to disperse and descend Qi, sweet to tonify the Spleen and Stomach, and salty to soften hardness and direct downward.
