About This Formula
Traditional Chinese Medicine background and properties
Formula Description
A modern formula designed for allergic rhinitis and nasal allergies, both seasonal and year-round. It works by strengthening the body's defensive capacity through the Lung, Spleen, and Kidney systems while dispelling Wind, opening the nasal passages, and reducing itching and discharge.
Formula Category
Main Actions
- Tonifies Lung and Kidney Qi

- Eliminates Dampness and transforms Phlegm
- Unblocks the Nasal Passages
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. Bi Qiu 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 Bi Qiu Tang addresses this pattern
When Lung Qi is deficient, the nose (the sensory orifice of the Lung) loses its nourishment and its Defensive Qi becomes weak. The exterior of the body becomes insecure, allowing Wind to penetrate easily and disturb the nasal passages. This results in frequent sneezing, runny nose with clear discharge, nasal congestion, and susceptibility to respiratory irritants. Bi Qiu Tang addresses this with its Qi-tonifying core of Dang Shen and Huang Qi, which directly replenish Lung Qi. Jie Geng lifts and diffuses Lung Qi upward to the nose, while Wu Wei Zi and He Zi astringe the Lung to prevent further Qi leakage. The Wind-expelling herbs (Fang Feng, Jing Jie, Bo He) clear the immediate invasion while the tonifying herbs prevent recurrence.
A practitioner would look for one or more of these signs
Frequent bouts of sneezing, especially on waking or exposure to cold air
Profuse clear, watery nasal discharge
Nasal stuffiness that worsens with cold or weather changes
Shortness of breath or weak voice
Fatigue and low resistance to colds
Spontaneous sweating and sensitivity to wind
Why Bi Qiu Tang addresses this pattern
The Spleen is the source of Qi and Blood production, and when Spleen Qi is deficient, the Lung (its child organ in the Five Element cycle) also becomes depleted. Furthermore, a weak Spleen fails to properly transform and transport fluids, leading to Dampness accumulation that manifests as watery nasal discharge and a heavy, foggy sensation in the head. Bi Qiu Tang addresses Spleen deficiency through Dang Shen, Bai Zhu, Shan Yao, and Yi Yi Ren, which collectively strengthen the Spleen, dry Dampness, and restore proper fluid metabolism. Ze Xie further drains accumulated fluids downward. This 'treating the mother to nourish the child' approach ensures the Lung receives adequate Qi supply from the Spleen.
A practitioner would look for one or more of these signs
Copious thin watery nasal discharge
Reduced appetite and loose stools
Persistent tiredness, especially after eating
Bloating and heaviness after meals
Nasal congestion with sensation of heaviness in the head
Why Bi Qiu Tang addresses this pattern
The Kidney is the root of all Qi in the body. When Kidney Qi is insufficient, it cannot grasp the Qi sent down by the Lung, and the body's ability to consolidate its exterior and resist external pathogens becomes fundamentally compromised. Chronic, long-standing allergies that persist year-round and worsen with age often reflect this deeper Kidney deficiency. The classical teaching that 'the Kidney governs sneezing' directly links Kidney Qi deficiency to the paroxysmal sneezing seen in allergic rhinitis. Bi Qiu Tang addresses this through Shan Yao, which tonifies the Kidney, while Wu Wei Zi astringes Kidney Qi to prevent its dissipation. The overall tonifying strategy of the formula gradually rebuilds the Kidney foundation.
A practitioner would look for one or more of these signs
Severe paroxysmal sneezing that is difficult to control
Lower back soreness and weakness
Frequent or clear urination
Deep constitutional fatigue and cold limbs
Persistent clear nasal discharge that is difficult to resolve
Why Bi Qiu Tang addresses this pattern
This pattern combines the underlying deficiency (weak Defensive Qi) with the active triggering factor (Wind invasion). When Defensive Qi is insufficient, the body's surface becomes porous to external pathogens, particularly Wind. Wind entering the nasal passages causes itching, sneezing, and discharge. This is the most clinically common presentation for allergic rhinitis, where patients have both constitutional weakness and active allergic symptoms. Bi Qiu Tang's combination of Huang Qi, Bai Zhu, and Fang Feng (the Yu Ping Feng San core) directly targets Defensive Qi deficiency, while the Wind-expelling herbs (Jing Jie, Fang Feng, Chan Tui, Bo He) address the active Wind invasion. This dual approach treats both the root weakness and the branch symptoms simultaneously.
A practitioner would look for one or more of these signs
Sudden onset sneezing triggered by wind, cold air, or allergens
Intense nasal and eye itching
Sudden onset of profuse watery nasal discharge
Alternating nasal blockage
Tendency to catch colds easily with spontaneous sweating
How It Addresses the Root Cause
Bi Qiu Tang addresses the condition known as Bi Qiu (鼻鼽), which corresponds to allergic rhinitis in modern medicine. The underlying disease mechanism is one of internal deficiency (the "root") combined with external invasion (the "branch"), making it a classic pattern of ben xu biao shi (本虚标实, root deficiency with branch excess).
The root problem lies in the weakness of three organ systems working together. The Lungs "open into the nose" and govern the body's defensive layer (Wei Qi). When Lung Qi is deficient, this protective barrier becomes porous, allowing Wind and Cold to penetrate the nasal passages easily. The Spleen, as the source of Qi and Blood production, is responsible for "generating" the Lung's Qi through the Earth-generating-Metal (土生金) relationship in Five Phase theory. When Spleen Qi is weak, it cannot adequately nourish the Lungs, compounding the Lung's defensive weakness. Meanwhile, the Kidneys serve as the "root of Qi," responsible for grasping and anchoring Qi. When Kidney Qi is insufficient, it fails to hold Qi in its proper place, and the body's warming function deteriorates, leaving the nasal passages cold and poorly nourished.
When Wind, Cold, or allergens (what classical texts call "unusual Qi" or 异气) invade through the weakened exterior, they lodge in the nasal orifices. The struggle between the weakened defensive Qi and the invading pathogen causes the sudden paroxysms characteristic of this condition: itchy nose, explosive sneezing, and profuse watery discharge. The fluids that pour from the nose represent the body's inability to contain and transform its own fluids properly, a direct consequence of the Qi deficiency failing to "hold" the body's fluids in place. The chronic, recurring nature of the condition reflects the persistent underlying organ deficiency that has never been adequately corrected.
Formula Properties
Slightly Warm
Predominantly sweet and acrid — sweet herbs tonify Qi of the Lungs, Spleen, and Kidneys, while acrid herbs open the nasal passages and disperse Wind from the exterior.
