Yang Yin Qing Fei Tang – "Throat Infection"

Soothing Inflamed Throats While Supporting Recovery

A classical Chinese herbal formula traditionally used to relieve severe sore throat, inflamed tonsils and persistent throat irritation by reducing inflammation, protecting delicate throat tissues and supporting the body's natural healing response.

​

What is Yang Yin Qing Fei Tang?

A sore throat is often one of the first signs that something is wrong.

For some people it remains mild.

For others, it quickly becomes the worst part of the illness.

Swallowing becomes painful.

Talking hurts.

The throat feels raw.

The glands become swollen.

Even drinking water becomes uncomfortable.

​

Chinese medicine recognised centuries ago that severe throat infections often represent a progression of inflammation deeper into the respiratory tract.

​

Rather than simply numbing the pain, Yang Yin Qing Fei Tang was developed to reduce inflammation while protecting the delicate tissues lining the throat.

​

At Chiron Medical we call it "Throat Infection", because it is specifically designed for significant inflammatory conditions affecting the throat and tonsils.

​

A Formula with More Than 300 Years of History

Yang Yin Qing Fei Tang first appeared in the Chong Lou Yu Yao (Essential Remedies from Chonglou) during the Qing Dynasty.

​

Originally developed for severe inflammatory throat disorders, the formula became highly regarded for its ability to calm inflammation while nourishing tissues damaged by prolonged infection.

​

Today it remains one of Chinese medicine's classic prescriptions for painful inflammatory disorders of the throat.

​

Why We Call It "Throat Infection"

Most sore throats are caused by inflammation.

Whether that inflammation is triggered by viruses or bacteria, the body's immune response produces:

• swelling

• redness

• pain

• difficulty swallowing

• enlarged lymph nodes

• irritation

As inflammation increases, the throat becomes increasingly damaged and uncomfortable.

Yang Yin Qing Fei Tang was designed to interrupt that inflammatory process while helping the tissues recover.

What Is It Traditionally Used For?

Traditionally, Yang Yin Qing Fei Tang is prescribed for Heat damaging the throat with depletion of Yin fluids.

In modern practice it is commonly considered for supportive management of:

• severe sore throat

• tonsillitis

• pharyngitis

• laryngitis

• recurrent throat infections

• persistent throat inflammation

• post-infectious throat irritation

It is particularly useful when the throat is red, swollen, painful and dry.

The Herbs That Make the Formula

A healthy throat is protected by a thin, moist lining that acts as both a physical barrier and an important part of the immune system. During a throat infection this delicate tissue becomes inflamed, swollen and painful as the immune system responds to invading bacteria or viruses. While this inflammatory response is essential for fighting infection, excessive inflammation can damage the very tissues it is trying to protect.

​

Yang Yin Qing Fei Tang was developed to restore that balance. Rather than simply suppressing inflammation, it combines herbs that calm excessive immune activity, soothe damaged tissues and support the natural healing process while the body clears the infection.

​

Sheng Di Huang (Fresh Rehmannia Root)

Traditional Role

Sheng Di Huang provides the restorative foundation of the formula. Traditionally it was used when inflammation had begun to dry and irritate the throat, helping protect tissues while supporting recovery from prolonged infection.

Biomedical Actions

Research demonstrates antioxidant and anti-inflammatory activity together with immune regulation and support for tissue repair. Experimental studies also suggest protection against oxidative injury and inflammatory damage within delicate epithelial tissues.

Mai Men Dong (Ophiopogon Root)

Traditional Role

Inflamed tissues heal best when they remain well hydrated. Mai Men Dong helps restore moisture to the throat, relieving irritation while protecting the delicate lining of the upper respiratory tract.

Biomedical Actions

Research suggests protection of respiratory mucosa, antioxidant and anti-inflammatory effects, together with support for epithelial regeneration and maintenance of mucosal barrier integrity.

Xuan Shen (Scrophularia Root)

Traditional Role

Xuan Shen helps settle the intense inflammatory response that often accompanies severe throat infections. It has traditionally been used when swelling, redness and pain become the dominant features of the illness.

Biomedical Actions

Research demonstrates anti-inflammatory, antimicrobial and antioxidant activity together with immune-modulating effects. Studies suggest it may help regulate inflammatory cytokines while supporting tissue recovery.

Bai Shao (White Peony Root)

Traditional Role

Bai Shao helps calm irritated tissues while supporting recovery during acute inflammation. Within the formula it provides balance, preventing excessive inflammatory activity from causing further tissue damage.

Biomedical Actions

Research suggests anti-inflammatory and antioxidant effects together with immune regulation, smooth muscle relaxation and protection against inflammatory tissue injury.

Mu Dan Pi (Moutan Bark)

Traditional Role

Inflamed tissues require both healthy circulation and controlled inflammation to heal effectively. Mu Dan Pi supports this process by helping restore normal blood flow while calming persistent inflammatory activity.

Biomedical Actions

Research demonstrates anti-inflammatory, antioxidant and vascular-protective effects together with immune modulation. Experimental studies also suggest inhibition of inflammatory mediators involved in tissue injury.

Bo He (Peppermint)

Traditional Role

Bo He provides rapid symptomatic relief by cooling and soothing an acutely inflamed throat. It also helps relieve the discomfort that accompanies swallowing during the early stages of infection.

Biomedical Actions

Research suggests antimicrobial, analgesic and anti-inflammatory activity. Its volatile oils provide a cooling sensation while demonstrating inhibitory effects against several respiratory pathogens.

Gan Cao (Liquorice Root)

Traditional Role

Gan Cao soothes irritated tissues while bringing the formula together into a balanced prescription. It has been used for centuries to relieve sore throats because of its ability to coat and protect inflamed mucous membranes.

Biomedical Actions

Research demonstrates antiviral, anti-inflammatory and antioxidant activity together with protection of respiratory mucosa. Glycyrrhizin has also been shown to influence immune function and may help reduce inflammatory damage during respiratory infections.

How the Formula Works

A sore throat is far more than a local infection. It is the result of an active immune response occurring within one of the body's most delicate protective barriers. As immune cells attack invading pathogens, inflammatory chemicals increase blood flow, recruit additional immune cells and activate pain receptors. While these processes are essential for controlling infection, they also produce the redness, swelling and pain that make swallowing so uncomfortable.

​

Chinese physicians recognised this balance centuries ago. Their aim was not simply to reduce pain, but to control excessive inflammation while protecting the tissues needed for recovery.

​

Yang Yin Qing Fei Tang reflects that philosophy. Some herbs help regulate the inflammatory response, others soothe and protect damaged mucous membranes, while others support tissue repair as the infection resolves. Modern research suggests the formula may reduce inflammatory signalling, limit oxidative stress, support epithelial repair and help regulate immune activity without interfering with the body's natural defence against infection.

​

This integrated approach helps explain why Yang Yin Qing Fei Tang has remained one of Chinese medicine's classic prescriptions for severe sore throat and inflammatory infections of the upper respiratory tract.

​

​

What Does Modern Research Say?

Research into the constituent herbs has investigated their role in:

Upper Respiratory Tract Infections

Studies suggest supportive effects on:

• sore throat severity

• inflammatory swelling

• mucosal healing

• immune regulation

Airway Protection

Research demonstrates:

• antioxidant activity

• protection of respiratory epithelial cells

• anti-inflammatory effects

• regulation of inflammatory cytokines

Comparing the Chiron Medical Infection Formulas

Respiratory infections often progress through recognisable stages. Selecting the correct formula depends on where the inflammation is now, not where it started.

​

Gui Zhi Tang - Colds, Shivers & Sniffles - Early chills, runny nose and mild cold symptoms - Supports the body's first response to Wind-Cold invasion

Yin Qiao San - No.1 Fever & Flu - Early fever, sore throat and viral respiratory infection - Clears early Heat and provides antiviral support

Sang Ju Yin - New Cough - Early cough with mild throat irritation - Protects the lungs as infection begins affecting the airways

Yang Yin Qing Fei Tang - Throat Infection - Severe sore throat, tonsillitis and inflamed throat tissues - Reduces inflammation while protecting and repairing the throat

Long Dan Xie Gan Tang - Liver Fire - Intense inflammatory Heat affecting specific organs - Clears severe inflammatory Heat

Wu Wei Xiao Du Yin - Inflammation - Skin infections, boils and spreading bacterial inflammation - Powerful antibacterial and anti-inflammatory support

Chuan Xin Lian Jie Du Tang - Break High Fever - High fever with severe systemic inflammatory illness - Intensive Heat-clearing and immune support

​

Understanding the Progression

Respiratory infections usually evolve rather than appearing all at once.

Colds, Shivers & Sniffles (Gui Zhi Tang)

The illness has only just begun.

↓

Fever & Flu (Yin Qiao San)

Heat develops with fever, sore throat and early viral symptoms.

↓

Throat Infection (Yang Yin Qing Fei Tang)

Inflammation becomes concentrated within the throat and tonsils.

Swallowing becomes painful.

The throat becomes intensely red, swollen and irritated.

↓

Liver Fire (Long Dan Xie Gan Tang)

If inflammatory Heat continues to intensify or localises elsewhere in the body, stronger Heat-clearing strategies may become appropriate.

↓

Inflammation (Wu Wei Xiao Du Yin)

Where bacterial skin or soft tissue infection develops with redness, swelling and pus, treatment shifts towards resolving Heat Toxin.

↓

Break High Fever (Chuan Xin Lian Jie Du Tang)

When inflammation becomes systemic, producing high fever and significant constitutional symptoms, stronger whole-body Heat-clearing support may be required.

Recognising this progression allows treatment to match the stage of illness rather than reacting only to individual symptoms.

Clinical Insights

Supporting Recovery Beyond the Acute Infection

Experienced practitioners often use Yang Yin Qing Fei Tang as the bridge between early respiratory infection and complete recovery.

Common combinations include:

Early Fever and Sore Throat

• Yin Qiao San (No.1 Fever & Flu)

when viral infection is still in its early stages.

Persistent Dry Cough After Throat Infection

• Bai He Gu Jin Tang (Dry Cough)

when throat inflammation has settled but dryness and persistent coughing remain.

Recurrent Throat Infections

• Yu Ping Feng San (Immunity)

to help rebuild immune resilience and reduce susceptibility to repeated infections once the acute illness has resolved.

Severe Inflammatory Heat

• Long Dan Xie Gan Tang (Liver Fire)

where marked inflammatory Heat extends beyond the throat or is accompanied by systemic signs of excess Heat.

High Fever

• Chuan Xin Lian Jie Du Tang (Break High Fever)

when severe throat infection is accompanied by high fever and intense constitutional symptoms.

For Traditional Chinese Medicine Practitioners

Classical Pattern

Heat Toxin injuring Lung and Stomach Yin

Typical presentation:

• severe sore throat

• swollen tonsils

• dry throat

• painful swallowing

• red tongue

• rapid pulse

Formula Strategy

Yang Yin Qing Fei Tang:

• Nourishes Yin.

• Clears Heat.

• Relieves throat swelling.

• Protects mucosal tissues.

• Supports recovery following inflammatory throat disease.

For Medical Doctors

Proposed Biomedical Actions

Current evidence suggests the constituent herbs influence:

• inflammatory cytokines

• oxidative stress

• epithelial repair

• immune regulation

• respiratory mucosal protection

Collectively these mechanisms may help reduce inflammatory tissue injury while supporting recovery of the upper respiratory tract.

Potential Herb–Drug Considerations

Clinical monitoring is advisable in patients taking:

• antibiotics

• corticosteroids

• anticoagulants

• immunosuppressive medications

Persistent sore throat lasting longer than one week, difficulty breathing, inability to swallow saliva, neck swelling, dehydration or suspected peritonsillar abscess requires urgent medical assessment.

Helping the Throat Heal

A throat infection can make even the simplest activities painful.

Eating.

Talking.

Swallowing.

Sleeping.

​

Yang Yin Qing Fei Tang recognises that healing requires more than simply reducing pain. The damaged tissues must also recover.

That is why we call it "Throat Infection."

​

Its purpose is to calm inflammation, protect delicate throat tissues and support the body's recovery so that swallowing, speaking and breathing become comfortable once again.
