About This Formula*
Traditional Chinese Medicine background and properties
Formula Description*
A formula centered on Chuan Bei Mu (Fritillaria) designed to stop coughing, transform phlegm, moisten the Lungs, and clear Heat from the respiratory tract. It is commonly used for cough with phlegm that is difficult to expectorate, sore throat, and respiratory discomfort from either Wind-Cold or Wind-Heat invading the Lungs.

Main Actions*
- Clears Lung Heat and Transforms Phlegm
- Stops Cough and Calms Wheezing
- Disperses Wind-Cold from the Exterior
- Descends Lung Qi and Stops Cough
- Transforms Dampness and Resolves Turbidity
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. Chuan Bei Jing 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 Chuan Bei Jing Tang addresses this pattern
When Heat lodges in the Lungs, it condenses the body's fluids into thick, sticky phlegm that is difficult to cough up. This creates a vicious cycle: the phlegm blocks the Lung's descending function, causing more Heat to build, which further thickens the phlegm. Chuan Bei Mu directly clears Lung Heat while dissolving the sticky phlegm. Jie Geng opens the Lung Qi to help expel the phlegm, while Ban Xia and Chen Pi work to dry residual Dampness and prevent phlegm from re-forming. Fu Ling strengthens the Spleen to cut off the root source of phlegm production.
A practitioner would look for one or more of these signs
Cough with thick, yellow, sticky phlegm difficult to expectorate
Sore, dry, or irritated throat
Wheezing or labored breathing with phlegm rattling
Feeling of fullness or oppression in the chest
Thirst with desire for cold drinks
Why Chuan Bei Jing Tang addresses this pattern
When Lung Yin is depleted — from chronic illness, dry environments, or prolonged Heat — the Lungs lose their natural moisture. Without adequate fluids, the Lungs cannot descend Qi smoothly, leading to a dry, persistent cough with scant, sticky phlegm or no phlegm at all. Chuan Bei Mu is particularly well-suited here because unlike many phlegm-resolving herbs that are drying, it simultaneously moistens the Lungs while transforming whatever phlegm remains. Gan Cao and Fu Ling provide gentle support without further depleting Yin.
A practitioner would look for one or more of these signs
Dry cough or cough with very little sticky phlegm
Dry, scratchy throat, worse in the evening
Night sweats or afternoon tidal heat
Dry mouth and throat
Why Chuan Bei Jing Tang addresses this pattern
When external Wind-Cold enters the body and lodges in the Lungs, it impairs the Lung's dispersing and descending functions, causing cough with thin, white, frothy phlegm, nasal congestion, and body aches. Some formulations of Chuan Bei Jing (particularly the patent medicine version) are indicated for this pattern. Jie Geng helps open and diffuse the constrained Lung Qi, while Ban Xia and Chen Pi transform the watery phlegm typical of Cold patterns. Fu Ling supports the Spleen to manage the excess fluid accumulation.
A practitioner would look for one or more of these signs
Cough with thin, white, frothy phlegm
Nasal congestion or runny nose with clear discharge
Generalized body aches and chills
Sneezing and mild aversion to cold
How It Addresses the Root Cause*
This formula addresses a pattern in which external Wind-Cold invades the body's surface and the Lungs, causing the Lung's normal descending and dispersing function to become blocked. When Lung Qi is constrained, it rebels upward, producing cough. At the same time, the Cold pathogen causes body fluids in the Lungs to congeal into thin, watery, white Phlegm that is difficult to expel. This obstruction of Qi and Phlegm in the chest leads to a sensation of chest stuffiness and oppression.
The person typically feels cold, has body aches, a stuffy nose, and little or no sweating, reflecting the exterior Cold blocking the pores and surface. The cough is heavy-sounding with copious clear or white sputum. Because the Lung governs Qi and controls respiration, the combined burden of exterior Cold constricting the airways and interior Phlegm obstructing the passages can also produce wheezing and labored breathing. In chronic cases such as recurring bronchitis, repeated exposure to Cold and accumulated Dampness-Phlegm in the Lungs perpetuates the cycle of cough and wheeze.
The formula helps by simultaneously releasing the exterior Cold (opening the surface to allow the pathogen to leave), restoring the Lung's ability to descend Qi properly (stopping the rebellious upward flow that causes cough), and dissolving the accumulated cold Phlegm so it can be expectored. This dual action on both the root cause (exterior invasion and Phlegm accumulation) and the symptoms (cough, wheeze, chest tightness) is what makes the formula effective for this pattern.
Formula Properties*
Warm
Predominantly bitter and acrid (pungent), with mild sweetness. The acrid taste disperses the exterior and moves Qi, the bitter taste descends and transforms Phlegm, and the sweetness harmonizes and moderates.
