About This Formula
Traditional Chinese Medicine background and properties
Formula Description
A classical formula designed to calm the Liver and stop internally generated Wind, used for conditions related to high blood pressure, dizziness, headache, and stroke risk caused by an overactive Liver and depleted Kidney Yin. It works by anchoring rising Qi and Blood back downward, calming the Liver, nourishing Yin, and preventing the chaotic upward rush that can lead to serious neurological symptoms.

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. Zhen Gan Xi Feng 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 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.
A practitioner would look for one or more of these signs
Dizziness that worsens with fatigue
Soreness and weakness of the lower back and knees
Difficulty sleeping with restless mind
Night sweats or heat sensations
How It Addresses the Root Cause
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
Cool
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.
