Xin Yi San – "Hayfever"

Helping You Breathe Freely Again

A classical Chinese herbal formula traditionally used to relieve hayfever, allergic rhinitis and chronic nasal congestion by reducing inflammation, opening the nasal passages and restoring healthy function of the upper respiratory tract.

 

What is Xin Yi San?

For many people, spring is beautiful.

For others...

It marks the beginning of months of misery.

​

The sneezing starts.

The nose blocks.

The eyes itch.

Sleep becomes difficult.

Concentration disappears.

​

Many people simply accept that hayfever is something they must endure every year.

Chinese medicine takes a different approach.

​

Rather than treating hayfever as simply "an allergy," it recognises that the body's immune response has become overly reactive to harmless substances such as pollen, grasses and dust.

​

Xin Yi San was developed to calm that response while restoring normal function to the nose and sinuses.

​

At Chiron Medical we call it "Hayfever", because it addresses the most recognisable symptoms of seasonal allergic rhinitis while helping people breathe freely again.

 

A Formula with More Than 700 Years of History

Xin Yi San first appeared in the Yan Shi Ji Sheng Fang (Formulas to Aid the Living) during the Song Dynasty in the 13th century.

​

It has remained one of Chinese medicine's classic prescriptions for allergic rhinitis and chronic nasal obstruction.

Its strength lies in restoring normal nasal function rather than simply suppressing symptoms.

 

Why We Call It "Hayfever"

Hayfever is much more than sneezing.

 

Typical symptoms include:

• repeated sneezing

• blocked nose

• runny nose

• itchy nose

• itchy eyes

• watery eyes

• sinus pressure

• reduced sense of smell

 

Many people also experience:

• poor sleep

• daytime fatigue

• reduced concentration

• mouth breathing

 

Xin Yi San was designed specifically for this pattern.

 

What Is It Traditionally Used For?

Traditionally, Xin Yi San is prescribed for chronic nasal obstruction due to Wind affecting the nasal passages, often occurring in people with an underlying weakness of the body's defensive system.

 

Allergic Rhinitis

Frequently prescribed for:

• seasonal hayfever

• perennial allergic rhinitis

• pollen allergies

• dust allergies

 

Nasal Congestion

Also used for:

• blocked nose

• chronic nasal obstruction

• recurrent sinus congestion

• impaired nasal breathing

​

The Herbs That Make the Formula

Xin Yi San combines ten carefully selected herbs that work together to reduce allergic inflammation, open blocked nasal passages, improve sinus drainage and support the body's natural immune defences.

​

Unlike formulas that simply suppress symptoms, Xin Yi San is designed to restore normal nasal function while helping the body recover from repeated allergic irritation.

 

Xin Yi Hua (Magnolia Flower)

Traditional role

The principal herb.

Opens the nasal passages and restores free breathing.

Biomedical actions

Research demonstrates:

• anti-inflammatory activity

• reduction of nasal mucosal swelling

• improved nasal airflow

• antioxidant effects

Xin Yi Hua has been one of Chinese medicine's premier herbs for nasal congestion for over a thousand years.

 

Bai Zhi (Angelica dahurica Root)

Traditional role

Opens the nose, relieves sinus congestion and reduces facial pain and headache.

Biomedical actions

Research suggests:

• anti-inflammatory activity

• analgesic effects

• antimicrobial properties

• improved sinus drainage

 

Qiang Huo (Notopterygium Root)

Traditional role

Expels external pathogens while relieving congestion affecting the head and upper respiratory tract.

Biomedical actions

• antioxidant activity

Fang Feng provides an important bridge between symptom relief and longer-term immune regulation.

 

Gao Ben (Ligusticum sinense Rhizome)

Traditional role

Relieves congestion affecting the top of the head while opening blocked nasal passages.

Biomedical actions

Research suggests:

• anti-inflammatory activity

• improved circulation

• analgesic effects

• relief of sinus-related headache

 

Chuan Xiong (Szechuan Lovage Root)

Traditional role

• immunomodulatory activity

• anti-inflammatory effects

• antioxidant properties

• support for mucosal immune function

 

Chuan Mu Tong (Clematis Stem)

Traditional role

Promotes the movement of fluids while helping reduce congestion and swelling within the nasal passages.

Biomedical actions

Research suggests:

• anti-inflammatory activity

• support for fluid regulation

• antioxidant effects

 

Shi Chang Pu (Anemone altaica Rhizome*)

Traditional role

Traditionally used to open blocked sensory pathways and improve the movement of Qi through the head.

Biomedical actions

Research suggests:

• neuroprotective activity

• anti-inflammatory effects

• antioxidant properties

• support for healthy upper respiratory function

Note: Some modern manufacturers substitute alternative herbs depending on regional practice and regulatory requirements.

 

Gan Cao (Liquorice Root)

Traditional role

Harmonises the formula while soothing irritated mucous membranes.

Biomedical actions

Research demonstrates:

• anti-inflammatory activity

• antiviral effects

• antioxidant activity

• protection of respiratory mucosa

 

Why This Formula Works So Well

Xin Yi San doesn't simply reduce sneezing.

​

It addresses several of the biological processes responsible for hayfever at the same time.

• Xin Yi Hua and Bai Zhi rapidly open blocked nasal passages and improve sinus drainage.

• Fang Feng helps regulate the body's exaggerated immune response to airborne allergens.

• Qiang Huo, Gao Ben and Chuan Xiong reduce inflammation, improve circulation and relieve sinus pressure and headache.

• Sheng Ma helps direct the formula towards the head and upper respiratory tract while supporting healthy mucosal immunity.

• Chuan Mu Tong assists in reducing congestion by promoting the movement of fluids.

• Gan Cao harmonises the prescription while soothing irritated nasal and respiratory tissues.

 

Rather than functioning like a conventional antihistamine, Xin Yi San works to restore normal physiology within the nose and sinuses by improving drainage, reducing inflammation and helping regulate the immune response that drives allergic symptoms.

Think of Xin Yi San as the formula that helps you through this hayfever season. Think of Yu Ping Feng San (Immunity) as the formula that helps prepare you for next hayfever season. Used together under the guidance of an experienced practitioner, they represent one of Chinese medicine's classic strategies: relieve today's symptoms while rebuilding tomorrow's resilience.

​

How the Formula Works

Modern allergy research shows that hayfever occurs when the immune system overreacts to otherwise harmless airborne allergens.

This produces:

• histamine release

• swelling of nasal tissues

• excessive mucus production

• itching

• sneezing

• congestion

 

Research suggests herbs contained within Xin Yi San may help:

• regulate inflammatory cytokines

• reduce allergic inflammation

• improve nasal airflow

• support healthy mucosal function

• reduce excessive immune reactivity

 

Rather than simply blocking symptoms, the formula aims to improve the health of the nasal passages while helping regulate the immune response responsible for allergic symptoms.

 

What Does Modern Research Say?

Research into the herbs contained within Xin Yi San has investigated:

 

Allergic Rhinitis

Studies suggest improvements in:

• nasal congestion

• sneezing

• rhinorrhoea

• nasal airflow

• quality of life

 

Inflammation

Research demonstrates:

• reduced inflammatory cytokines

• antioxidant activity

• immune modulation

• improved respiratory mucosal health

 

These findings closely align with the traditional use of the formula for allergic rhinitis.

 

Hayfever Is More Than a Nose Problem

Chinese medicine has always recognised that hayfever rarely begins in the nose.

The nose is simply where the symptoms appear.

​

The underlying problem often lies within the body's ability to regulate its own immune response.

This is why experienced practitioners rarely stop at simply treating sneezing.

​

They also ask:

"Why has this person become so sensitive in the first place?"

​

That question often leads to one of Chinese medicine's most important preventive formulas...

Yu Ping Feng San.

​

Comparing the Chiron Medical Nasal & Allergy Formulas

Different formulas are selected depending on whether the problem is an allergy, an infection or a weakened immune system.

​

Gui Zhi Tang - Colds, Shivers & Sniffles - Early cold with sneezing, chills and runny nose - Supports the body's first immune response during viral infection

Xin Yi San -  Hayfever - Seasonal allergies, sneezing, itchy nose and blocked sinusesReduces allergic inflammation and opens the nasal passages

Bi Min Gan Tang - Sinus Infection - Chronic sinus congestion, facial pressure and infected sinuses - Clears inflammation, drains the sinuses and treats deeper sinus disease

Yu Ping Feng San - Immunity - Recurrent hayfever, repeated respiratory infections and immune weakness - Strengthens long-term immune resilience and reduces susceptibility to recurrent illness

 

Understanding the Progression

Not every blocked nose has the same cause.

Recognising the underlying pattern helps determine the most appropriate treatment.

Colds, Shivers & Sniffles (Gui Zhi Tang)

The illness has only just begun.

Typical symptoms include:

• chills

• runny nose

• sneezing

• mild headache

• body aches

The cause is an acute viral infection.

↓

Hayfever (Xin Yi San)

The infection has gone.

Instead, the immune system is reacting excessively to pollen, dust or environmental allergens.

Typical symptoms include:

• sneezing

• itchy nose

• watery eyes

• clear nasal discharge

• blocked nose

↓

Sinus Infection (Bi Min Gan Tang)

Persistent inflammation allows mucus to accumulate within the sinuses.

Typical symptoms include:

• facial pain

• sinus pressure

• thick yellow or green mucus

• blocked nose

• headache

• reduced sense of smell

↓

Immunity (Yu Ping Feng San)

Once symptoms are controlled, the focus shifts towards reducing the likelihood of recurrence.

Rather than treating today's allergy, Yu Ping Feng San helps strengthen the body's natural defensive barrier and improve immune regulation before the next allergy season arrives.

This progression reflects one of the central principles of Chinese medicine:

Treat the current condition, then strengthen the person.

 

Clinical Insights

 

Treating Today's Symptoms While Preventing Next Season's

Experienced practitioners frequently combine Xin Yi San with other formulas depending on the patient's presentation.

 

Seasonal Hayfever

During the allergy season:

• Xin Yi San remains the primary formula for relieving sneezing, nasal congestion and allergic rhinitis.

 

Recurrent Hayfever

Between allergy seasons:

• Yu Ping Feng San (Immunity) is commonly prescribed to improve immune resilience and reduce susceptibility to future allergic episodes.

 

Chronic Sinus Disease

Where long-standing inflammation has progressed to recurrent sinus infection:

• Bi Min Gan Tang (Sinus Infection) is often added to improve sinus drainage and reduce chronic inflammation.

 

Early Viral Illness

If sneezing and a runny nose are caused by the beginning of a viral cold rather than allergy:

• Gui Zhi Tang (Colds, Shivers & Sniffles) becomes the more appropriate choice.

 

This layered approach allows treatment to evolve as the underlying cause changes—from viral infection, to allergic inflammation, to chronic sinus disease, and finally to rebuilding long-term immune resilience.

 

For Traditional Chinese Medicine Practitioners

 

Classical Pattern

Wind invading the nasal passages with underlying Lung Qi and Wei Qi deficiency

 

Typical presentation:

• sneezing

• clear nasal discharge

• blocked nose

• itchy nose

• recurrent allergic rhinitis

• aversion to wind

• pale tongue

• floating or deficient pulse

 

Formula Strategy

Xin Yi San:

• Opens the nasal passages.

• Expels Wind.

• Reduces allergic inflammation.

• Restores normal nasal function.

• Supports healthy respiratory circulation.

 

Frequently combined with Yu Ping Feng San when constitutional Wei Qi deficiency contributes to recurrent allergic disease.

 

For Medical Doctors

 

Proposed Biomedical Actions

Current research suggests the constituent herbs may influence:

• mast cell activation

• histamine-mediated inflammatory responses

• inflammatory cytokines

• nasal mucosal oedema

• mucociliary clearance

• epithelial barrier function

 

Collectively these actions may contribute to reduced allergic inflammation, improved nasal airflow and healthier sinus function.

 

Potential Herb–Drug Considerations

Clinical monitoring is advisable in patients taking:

• antihistamines

• intranasal corticosteroids

• systemic corticosteroids

• immunotherapy for allergic disease

 

Persistent unilateral nasal obstruction, recurrent nosebleeds, high fever, facial swelling or severe sinus pain should always be medically assessed to exclude structural disease or significant bacterial infection.

 

Looking Beyond Allergy Season

For many people, hayfever becomes something they simply expect each year.

Chinese medicine offers a different perspective.

​

Instead of asking only, "How do I stop the sneezing?"

​

it also asks, "Why has my immune system become so reactive?"

​

That philosophy makes Xin Yi San much more than a seasonal allergy formula.

It provides relief during the allergy season while opening the door to long-term immune support through formulas such as Yu Ping Feng San.

​

That is why we call it "Hayfever."

​

Because breathing freely shouldn't be something you only enjoy outside of spring—it should be part of everyday life.
