Patterns Addressed
In TCM, symptoms don't appear randomly — they cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Zhen Gan Xi Feng Tang is designed to correct these specific patterns.
Why Zhen Gan Xi Feng Tang addresses this pattern
When Liver and Kidney Yin are depleted over time, Yin can no longer anchor Yang, and Liver Yang rises unchecked to the upper body. This produces dizziness, headache with a sensation of heat, tinnitus, eye distension, facial flushing, and irritability. The pulse is characteristically wiry, long, and forceful. Zhen Gan Xi Feng Tang directly addresses this by using Niu Xi and Dai Zhe Shi to strongly direct the rebellious Qi and Blood back downward, while Long Gu, Mu Li, Gui Ban, and Bai Shao anchor the floating Yang and nourish the depleted Yin at its root. The Yin-nourishing herbs (Xuan Shen, Tian Dong, Gui Ban, Bai Shao) replenish the Kidney Water needed to keep Liver Wood in check, treating the underlying cause.
A practitioner would look for one or more of these signs
Persistent or severe dizziness and vertigo
Headache with sensation of heat or distension in the head
Ringing in the ears
Face red as if intoxicated
Restlessness and irritability with heat sensation in the chest
High blood pressure with a wiry, forceful pulse
Why Zhen Gan Xi Feng Tang addresses this pattern
When Liver Yang rising progresses further, it transforms into internal Wind. This is a more severe stage where the chaotic upward movement of Qi and Blood can cause tremors, numbness, progressive limb weakness, facial deviation, and in acute cases, sudden collapse with loss of consciousness. Zhang Xichun called this 'internal Wind stroke' (类中风) and equated it with what Western medicine terms cerebral hemorrhage. The formula's heavy descending and sedating action (Niu Xi, Dai Zhe Shi, Long Gu, Mu Li) directly quells the acute Wind, while the Yin-nourishing herbs address the fundamental Yin deficiency that allowed Wind to generate. The Liver-soothing trio (Yin Chen, Chuan Lian Zi, Mai Ya) prevents the suppressive force from worsening the Liver's agitation.
A practitioner would look for one or more of these signs
Trembling of limbs, head, or tongue
Numbness or tingling in the extremities
Progressive weakness or paralysis on one side
Deviation of the mouth and eyes
Sudden collapse with loss of consciousness, recovering after some time
Severe vertigo leading to falling
Why Zhen Gan Xi Feng Tang addresses this pattern
This is the root pattern underlying both Liver Yang Rising and Liver Wind. Chronic illness, aging, emotional strain, or constitutional weakness depletes the Yin of the Liver and Kidneys. When Kidney Yin fails to nourish and anchor Liver Yang, Yang rises and eventually generates Wind. The formula addresses this root through Gui Ban, Bai Shao, Xuan Shen, and Tian Dong, which together deeply nourish Liver and Kidney Yin. Niu Xi also contributes by tonifying the Liver and Kidneys. Zhang Xichun noted that in cases with particularly weak Kidney pulses, one should add Shu Di Huang and Shan Zhu Yu to further strengthen this root treatment.

Commonly Prescribed For
These conditions can arise from the patterns above. A practitioner would consider Zhen Gan Xi Feng Tang when these conditions are specifically caused by those patterns — not for all cases of these conditions.
TCM Interpretation
In TCM, what Western medicine calls high blood pressure most commonly corresponds to Liver Yang Rising from an underlying Liver and Kidney Yin Deficiency. The Liver governs the smooth flow of Qi throughout the body, and the Kidneys store the body's foundational Yin. When Kidney Yin becomes depleted (through aging, chronic stress, overwork, or constitutional factors), it can no longer anchor and nourish the Liver. The Liver's Yang then rises unchecked, dragging Qi and Blood upward to the head. This produces the characteristic cluster of symptoms: dizziness, throbbing headache, facial flushing, tinnitus, and irritability. The wiry, long, forceful pulse that Zhang Xichun identified as the key diagnostic sign directly reflects this pattern of excessive upward force.
Why Zhen Gan Xi Feng Tang Helps
Zhen Gan Xi Feng Tang addresses hypertension through a multi-layered strategy. Niu Xi and Dai Zhe Shi at heavy dosages (30g each) powerfully redirect the upward-surging Qi and Blood back downward, which can produce relatively rapid relief of acute symptoms. Long Gu, Mu Li, and Gui Ban anchor the floating Yang and calm the spirit. Gui Ban, Bai Shao, Xuan Shen, and Tian Dong replenish the depleted Kidney and Liver Yin, addressing the root imbalance that drives the elevated blood pressure over time. Modern research has demonstrated that this formula can reduce blood pressure in spontaneously hypertensive rats and improve vascular health, supporting its traditional use.
TCM Interpretation
Zhang Xichun specifically created this formula for what he called 'internal Wind stroke' (类中风, lei zhong feng), distinguishing it from stroke caused by external Wind invasion. In TCM understanding, when Liver and Kidney Yin are severely depleted, Liver Yang rises to an extreme and transforms into internal Wind. This Wind drives Qi and Blood into a chaotic upward rush, overwhelming the brain. In mild cases this produces progressive limb weakness and facial deviation (Wind affecting the channels); in severe cases it causes sudden collapse, loss of consciousness, and paralysis (Wind affecting the organs). Zhang Xichun explicitly connected this to the Su Wen concept of Qi and Blood rushing upward together causing 'great reversal.'
Why Zhen Gan Xi Feng Tang Helps
The formula targets stroke through its heavy downward-anchoring strategy. Niu Xi pulls Blood downward from the head, acting as what Zhang Xichun called the primary herb for treating the acute manifestation. Dai Zhe Shi descends Qi alongside it. Long Gu, Mu Li, and Gui Ban subdue the Liver Wind that drives the crisis. Crucially, the Yin-nourishing herbs (Xuan Shen, Tian Dong, Gui Ban, Bai Shao) address the underlying deficiency to prevent recurrence. The formula can be used in the pre-stroke phase (when warning signs like progressive dizziness and limb numbness appear) to potentially prevent full stroke, during the acute phase, and in recovery. Clinical studies have shown improved outcomes in acute cerebral hemorrhage patients when this formula is added to standard care.
TCM Interpretation
Dizziness and vertigo are among the most common symptoms of Liver Yang Rising. In TCM, the head is the 'meeting place of all Yang,' and when Liver Yang surges upward excessively, it disturbs the clear Yang that should reside in the head. The patient experiences spinning sensations, unsteadiness, a feeling of heaviness at the top and lightness at the bottom (as if walking on cotton), and sometimes a sensation of heat or pressure in the head. This is particularly common in middle-aged and older adults with a background of Liver-Kidney Yin depletion and a wiry, forceful pulse.
Why Zhen Gan Xi Feng Tang Helps
Zhen Gan Xi Feng Tang is one of the most frequently used formulas for vertigo associated with Liver Yang Rising. The combination of Niu Xi directing Blood downward, Dai Zhe Shi descending Qi, and Long Gu and Mu Li anchoring Yang directly addresses the upward disturbance causing dizziness. Bai Shao, Gui Ban, Xuan Shen, and Tian Dong nourish the Yin root to produce lasting improvement. Clinical practitioners note that this formula is particularly well suited when dizziness is accompanied by a flushed face, sensation of head heat, irritability, and a wiry forceful pulse, helping distinguish its use from other dizziness formulas.

How It Addresses the Root Cause
TCM doesn't just suppress symptoms — it aims to resolve the underlying imbalance. Here's how Zhen Gan Xi Feng Tang works at the root level.
The core disease mechanism addressed by Zhen Gan Xi Feng Tang is internal Wind generated by Liver Yang rising, rooted in Liver and Kidney Yin deficiency. In TCM theory, the Liver is a Wood-phase organ that stores Blood and governs the smooth flow of Qi. When Kidney and Liver Yin become depleted (from aging, chronic illness, emotional strain, or overwork), they can no longer anchor the Liver's Yang aspect. This unanchored Yang rises unchecked, and when it intensifies further, it transforms into internal Wind.
Zhang Xichun explains that when Liver Wood's fire blazes, the Lung's descending function fails, the Kidney's anchoring function weakens, and the Qi of the Penetrating Vessel (Chong Mai) and Stomach also rebel upward. All the organ systems' Qi moves excessively upward, carrying Blood up to the brain. The brain's blood vessels become overfilled, affecting the nervous system. In mild cases, this produces headache with a sensation of heat in the head, dizziness, eye distension, ear ringing, a flushed face, and irritability. In severe cases, the chaotic upward surging of Qi and Blood leads to sudden collapse, loss of consciousness, and what he terms "internal Wind-stroke" (equivalent to what he recognized as cerebral hemorrhage or severe hypertension).
Crucially, this is not Wind coming from outside the body. The Wind is generated internally by the body's own imbalance. Zhang Xichun specifically warns that confusing this with externally-contracted Wind and using dispersing herbs would be disastrous, as such herbs would drive more Blood upward to the brain. The underlying pattern is one of excess above (Yang and Wind surging to the head) combined with deficiency below (depleted Yin failing to anchor), with the acute excess being the dominant clinical concern.
Formula Properties
Every formula has an inherent temperature, taste, and affinity for specific organs — these properties determine how it interacts with the body
Overall Temperature
Taste Profile
Predominantly salty and bitter with some sweet notes. The salty quality (from shells and minerals) softens hardness and anchors the Yang downward, while the bitter quality (from Xuan Shen, Chuan Lian Zi, Yin Chen) clears Heat and descends. The sweet taste of Gan Cao and Mai Ya harmonizes and protects the Stomach.
