Formula Overview
The foundational classical formula for exterior excess Wind-Cold attack. Characterised by chills more severe than fever, absence of sweating, body aches, headache and possible wheezing with thin white sputum.
Therapeutic Principle
Traditionally selected for excess Wind-Cold with a closed exterior — marked chills, body aches and a complete absence of sweating — rather than the sweating, deficiency-type presentation that calls for Gui Zhi Tang, and before the pattern has transformed into the Lung Heat with thirst and wheezing addressed by Ma Xing Shi Gan Tang.

Actions
- Induces sweating to release the exterior
- diffuses the lung to calm labored breathing.
Indications
- Ma Huang Tang is indicated for an externally contracted wind-cold exterior-excess pattern.
- The symptoms are aversion to cold, headache, generalized body pain, absence of sweating, and labored breathing.
Tongue & pulseThe tongue coating is thin and white, and the pulse is superficial and tight.
Traditional Pathogenesis
Cause & mechanism
- This pattern is due to externally contracted wind-cold which causes the lung qi failing to diffuse.
- The invasion of the exterior by external wind-cold obstructs the wei yang, blocks and congests the striae and interstices, constrains ying yin, and obstructs the channels.
- The lung governs the qi and belongs to wei, which is connected with the skin and body hair at the body’s exterior.
- The regular diffusion and descent of lung qi is affected when the exterior of the body is restrained by wind-cold.
- The body’s exterior is linked internally with the lung.
- Therefore, the tension of the body’s exterior constrains the lung qi within.
- The constrained lung qi ascends counter-flow to induce labored breathing.
Clinical presentation
- The result is aversion to cold, fever, absence of sweating, headache, and generalized pain.
- Thin and white tongue coating and a superficial, tight pulse are indications of an exterior pattern fettered by wind-cold.
Treatment strategy
- The treatment is to induce sweating to release the exterior and diffuse the lung to calm labored breathing.
How does this formula compare?
Clinical Perspective
Ma Huang Tang addresses excess Wind-Cold with no sweating (closed exterior). Gui Zhi Tang is used for deficient Wind-Cold with sweating. Ma Xing Shi Gan Tang is chosen when the pattern has shifted to Lung Heat with wheezing and thirst. Sang Ju Yin addresses mild early-stage Wind-Heat cough.
Clinical Differentiation
- Ma Huang Tang is used to treat an externally contracted wind-cold exterior-excess pattern.
- It is both a fundamental and a representative formula.
- This clinical pattern is marked by aversion to cold, fever without sweating, labored breathing, superficial and tight pulse.
Safety notes: To avoid qi consumption and fluid damage, this formula should not be overdosed because of its drastic sweat-inducing effect. It is not applicable for patients with patterns such as exterior-deficiency wind-cold, exterior wind-heat, and exterior wind-cold with a weak constitution.

Frequently Asked Questions
What are the actions of Ma Huang Tang?
Ma Huang Tang has the actions of inducing sweating to release the exterior, disseminating Lung Qi, and calming wheezing. It is the classic Shang Han Lun formula for exterior Wind-Cold excess (Taiyang Shang Han) in which the pores are tightly closed and the pathogen has no outlet.
Which modern diseases is Ma Huang Tang suited to?
Modern TCM clinical practice commonly applies it to individuals whose pattern differentiation falls within exterior Wind-Cold excess, including the common cold or influenza with no sweating and strong chills, acute bronchitis or bronchial asthma with exterior Cold signs, and certain acute upper respiratory conditions presenting with body aches and a floating tight pulse.
Is Ma Huang Tang suitable for improving severe chills, fever without sweating, and body aches?
For presentations of severe aversion to cold, fever, complete absence of sweating, headache, generalized body aches, possible wheezing or tight chest, a thin white tongue coating, and a floating tight pulse — in those whose pattern differentiation confirms Taiyang Wind-Cold excess — TCM commonly applies Ma Huang Tang as an adjunct. It cannot replace standard medical treatment.
