Er Xian Tang – "Hot Flushes"

A modern Chinese herbal formula traditionally used to relieve hot flushes, night sweats and other symptoms of menopause by restoring the natural balance between Yin and Yang.

 

What is Er Xian Tang?

For many women, menopause is much more than simply the end of menstruation.

 

It can affect:

• body temperature

• sleep

• mood

• energy

• memory

• libido

• bone health

• quality of life

 

One of the most recognisable symptoms is the hot flush.

A sudden wave of heat rises through the chest, neck and face.

Sweating follows.

Sleep is interrupted.

Confidence can suffer.

​

Traditional Chinese Medicine (TCM) recognised that these symptoms occur because the body's internal balance begins to change with age.

​

Er Xian Tang (二仙汤) was developed specifically to restore that balance.

​

At Chiron Medical we call it "Hot Flushes", because reducing the frequency and severity of vasomotor symptoms is its most recognised clinical application.

​

A Modern Classical Formula

 

Unlike many famous Chinese herbal prescriptions, Er Xian Tang is not an ancient formula.

​

It was developed in Shanghai during the 1950s by Professor Zhang Bo-Na, one of China's leading physicians in women's health, specifically to treat menopausal syndrome. Since then it has become one of the most widely researched Chinese herbal formulas for menopause and healthy ageing.

​

Today it is prescribed throughout China and has been investigated in numerous clinical and experimental studies involving menopause, osteoporosis and age-related hormonal decline. 

 

Why We Call It "Hot Flushes"

Most women recognise the symptoms immediately.

 

Common complaints include:

• hot flushes

• night sweats

• facial flushing

• disturbed sleep

• irritability

• fatigue

• reduced libido

• vaginal dryness

• poor concentration

 

Chinese medicine views these symptoms as a gradual loss of harmony between the body's warming (Yang) and cooling (Yin) systems.

​

Er Xian Tang was specifically designed to restore that balance.

 

What Is It Traditionally Used For?

Traditionally, Er Xian Tang is prescribed for Kidney Yin and Kidney Yang Deficiency with Deficiency Heat.

 

Menopause

• hot flushes

• night sweats

• menopausal fatigue

• emotional irritability

• reduced libido

• disturbed sleep

 

Healthy Ageing

Modern practitioners also prescribe the formula to support:

• age-related hormonal changes

• bone health

• healthy ageing

• vitality during menopause

 

Other Traditional Uses

Research has also explored supportive applications in:

• osteoporosis

• premature ovarian insufficiency

• male androgen decline (pattern dependent)

 

The Herbs That Make the Formula

Er Xian Tang combines six herbs that work together to support the body's natural adaptation to menopause. Rather than replacing hormones, the formula has traditionally been used to help the body regulate temperature, maintain energy, support bone health and promote a smoother transition through hormonal change.

 

Xian Mao (Curculigo Rhizome)

 

Traditional Role

Xian Mao is one of the formula's primary restorative herbs. Traditionally used to improve vitality and resilience, it helps restore warmth, strength and physical energy during times of hormonal decline.

 

Biomedical Actions

Research suggests it may support endocrine function, bone metabolism, antioxidant activity and resistance to fatigue.

 

Yin Yang Huo (Epimedium)

 

Traditional Role

Often called the "bone and vitality" herb, Yin Yang Huo has long been used to support healthy ageing, maintain mobility and promote hormonal balance.

 

Biomedical Actions

Research demonstrates phytoestrogen-like activity, improved bone density, cardiovascular support, endothelial protection and antioxidant effects.

 

Ba Ji Tian (Morinda Root)

 

Traditional Role

Ba Ji Tian supports strength and stamina while helping maintain healthy bones and joints as the body adapts to changing hormone levels.

 

Biomedical Actions

Studies suggest anti-inflammatory, immune-modulating and endocrine-regulating effects, together with support for bone health.

 

Dang Gui (Chinese Angelica Root)

 

Traditional Role

Dang Gui has traditionally been used throughout a woman's reproductive life to support healthy circulation and nourish the body's recovery during periods of hormonal change.

 

Biomedical Actions

Research demonstrates improvements in microcirculation together with anti-inflammatory, antioxidant and vascular-protective effects.

 

Huang Bai (Phellodendron Bark)

 

Traditional Role

As the body adjusts to menopause, Huang Bai helps calm the internal "heat" traditionally associated with hot flushes, night sweats and irritability.

 

Biomedical Actions

Research suggests anti-inflammatory, antioxidant and antimicrobial activity, together with regulation of inflammatory signalling pathways.

 

Zhi Mu (Anemarrhena Rhizome)

 

Traditional Role

Zhi Mu complements Huang Bai by helping cool the body and relieve dryness, making it particularly valuable for women experiencing hot flushes, night sweats and restless sleep.

 

Biomedical Actions

Research demonstrates anti-inflammatory and antioxidant effects, while supporting bone metabolism and healthy endocrine function.

 

How the Formula Works

 

Menopause is now recognised as far more than a simple decline in oestrogen. It is a whole-body transition involving changes in hormone regulation, temperature control, sleep, bone health, metabolism and inflammatory signalling.

 

Er Xian Tang has been used for centuries to help women adapt to this transition more comfortably. Rather than replacing hormones, the formula supports the body's own regulatory systems, helping restore balance as hormone levels naturally change.

 

Modern research suggests Er Xian Tang may help regulate the hypothalamic-pituitary-ovarian axis, reduce hot flushes and night sweats, support bone metabolism, calm inflammatory pathways and improve sleep quality. Together, these actions help explain why it has remained one of Chinese medicine's most respected formulas for managing menopausal symptoms naturally.

 

What Does Modern Research Say?

Er Xian Tang is one of the most extensively researched Chinese herbal formulas for menopausal symptoms.

 

Menopause

Clinical studies have investigated:

• hot flush frequency

• hot flush severity

• night sweats

• sleep quality

• overall menopausal symptoms

 

Bone Health

Research suggests supportive effects on:

• bone mineral density

• osteoblast activity

• reduction of bone resorption

 

Endocrine Function

Experimental studies suggest the formula may influence:

• hypothalamic-pituitary-ovarian regulation

• sex hormone balance

• immune function

• oxidative stress (ScienceDirect)

 

While larger high-quality trials are still needed, current evidence supports its role as an adjunctive therapy for menopausal symptom management.

 

More Than Hot Flushes

Although we call it "Hot Flushes," Er Xian Tang addresses much more than temperature regulation.

 

The transition through menopause can influence:

• sleep

• mood

• energy

• bones

• joints

• cardiovascular health

• sexual wellbeing

 

By restoring balance between Yin and Yang, the formula aims to support the whole person—not just one symptom.

 

Comparing the Chiron Medical Menopause Formulas

Although both formulas support women through menopause, they are designed for different constitutional patterns.

​

Er Xian Tang - Hot Flushes - Women experiencing frequent hot flushes, night sweats and fluctuating body temperatureBalances Kidney Yin and Yang while regulating menopausal symptoms

Zhi Bai Di Huang Tang - Menopause - Women with longstanding Yin deficiency, dryness and deficiency HeatNourishes Kidney Yin, restores body fluids and cools chronic deficiency Heat

 

How Er Xian Tang and Zhi Bai Di Huang Tang Work Together

Although both formulas are used to support each other and those who take during menopause, they are not interchangeable.

 

Er Xian Tang ("Hot Flushes") is often chosen when vasomotor symptoms are the dominant complaint. Women commonly experience intense hot flushes, night sweats, sleep disturbance and fluctuating body temperature. The formula is unique because it supports both Kidney Yin and Kidney Yang simultaneously, helping the body adapt to hormonal change rather than simply cooling the symptoms.

 

Zhi Bai Di Huang Tang ("Menopause"), on the other hand, is generally more appropriate when there is deep Yin depletion. Women often complain of persistent dryness, burning sensations, night sweats, dry mouth, dry skin and long-standing constitutional depletion. Its emphasis is on replenishing body fluids and calming chronic deficiency Heat.

​

In practice, many women move between these patterns as menopause progresses. One formula may be more appropriate in the early transition, while the other becomes more suitable later, depending on the individual's presentation. This pattern-based approach is one of the great strengths of Traditional Chinese Medicine, allowing treatment to evolve as symptoms change.

​

For Traditional Chinese Medicine Practitioners

 

Classical Pattern

Kidney Yin and Yang Deficiency with Deficiency Heat

 

Typical presentation:

• hot flushes

• night sweats

• lumbar weakness

• fatigue

• irritability

• insomnia

• red tongue with little coating

• deep deficient pulse

 

Formula Strategy

Er Xian Tang:

• Tonifies Kidney Yin.

• Tonifies Kidney Yang.

• Clears Deficiency Heat.

• Nourishes Blood.

• Harmonises the Chong and Ren vessels.

 

Common Clinical Modifications

Frequently adapted for:

• menopausal syndrome

• premature ovarian insufficiency

• osteoporosis

• male climacteric syndrome

• age-related endocrine decline

 

For Medical Doctors

 

Proposed Biomedical Actions

Current research suggests the constituent herbs influence:

• hypothalamic-pituitary-ovarian axis regulation

• thermoregulation

• bone remodelling

• inflammatory cytokines

• oxidative stress

• immune modulation

• vascular function

 

Major bioactive compounds include:

• icariin

• berberine

• mangiferin

• ferulic acid

• curculigosides

• anemarrhenasaponins

 

Collectively these compounds demonstrate phytoestrogen-like, osteoprotective, antioxidant and immunomodulatory activities that may help explain the formula's traditional role in menopausal care. (ScienceDirect)

 

Potential Herb–Drug Considerations

Clinical monitoring is advisable in women taking:

• menopausal hormone therapy (MHT/HRT)

• selective oestrogen receptor modulators

• bisphosphonates

• antihypertensive medications

• anticoagulants

 

Women experiencing postmenopausal bleeding, unexplained weight loss, persistent pelvic pain or new breast symptoms should undergo prompt medical assessment. Er Xian Tang is intended as supportive therapy and should complement, not replace, evidence-based medical care.

 

Finding Balance Through Change

Menopause is not an illness.

It is one of life's natural transitions.

For many women, however, that transition is accompanied by symptoms that affect sleep, confidence, relationships and quality of life.

​

Er Xian Tang was created to help women move through this stage with greater comfort and resilience.

That is why we call it "Hot Flushes."

​

By supporting the body's natural balance between Yin and Yang, this remarkable formula helps reduce one of menopause's most recognisable symptoms while supporting the broader health changes that accompany healthy ageing.

​

Key Takeaways

• Er Xian Tang is a modern Chinese herbal formula developed in the 1950s specifically for menopausal syndrome and is one of the most extensively researched formulas for hot flushes. (PubMed)

• At Chiron Medical it is called "Hot Flushes" because it is primarily used to support women experiencing vasomotor symptoms, night sweats and menopausal temperature instability.

• It differs from Zhi Bai Di Huang Tang ("Menopause"), which is more strongly focused on nourishing Kidney Yin and treating longstanding dryness and deficiency Heat.

• Modern research supports actions on thermoregulation, bone health, endocrine function and inflammatory pathways, although further high-quality clinical studies are still needed. (ScienceDirect)

• The formula should be prescribed by a qualified Chinese medicine practitioner and used alongside appropriate medical care as part of an individualised menopause management plan.

Clinical Insights

 

Menopause rarely presents the same way in every woman. While hot flushes may be the most recognised symptom, they are often accompanied by disturbed sleep, mood changes, fluctuating body temperature, fatigue or an underlying constitutional weakness. For this reason, experienced practitioners rarely view Er Xian Tang as a stand-alone solution. Instead, it forms the centre of a treatment strategy that can be tailored to the individual's pattern of symptoms.

 

Alternating Hot Flushes and Chills

Some women describe swinging between feeling intensely hot one moment and unusually cold the next, as though the body's internal thermostat cannot settle. This pattern suggests the body's temperature regulation has become unstable rather than simply "too hot."

Er Xian Tang is commonly combined with:

• X factor (Xiao Chai Hu Wan) to help regulate these alternating temperature fluctuations and restore a more stable physiological rhythm.

 

Emotional Volatility and Dysphoria

Hormonal change affects far more than temperature regulation. Irritability, anxiety, emotional sensitivity and feelings of being overwhelmed frequently accompany menopause and can significantly reduce quality of life.

Depending on the predominant presentation, Er Xian Tang may be combined with:

• Happy Heart Formula (Gan Mai Da Zao Wan Jia Wei) where emotional sensitivity, anxiety and low mood predominate.

• Angry Gallbladder (Wen Dan Tang) when emotional symptoms are accompanied by mental restlessness, worry or a sense of internal agitation.

 

Insomnia and Disturbed Sleep

Many women find that sleep becomes lighter and less restorative during menopause. Difficulty falling asleep, frequent waking or waking overheated can all contribute to daytime fatigue.

To improve sleep quality, Er Xian Tang is commonly combined with:

• The Chill Pill (An Shen Ding Zhi Wan) to promote calmer, more restorative sleep.

• Angry Gallbladder (Wen Dan Tang) when restless sleep is associated with mental overactivity or vivid dreaming.

 

Constitutional Deficiency

For some women, menopausal symptoms develop on the background of longstanding constitutional weakness. In these cases, addressing the underlying decline often produces better long-term results than simply treating hot flushes alone.

Where reduced vitality and declining warmth predominate, practitioners may combine Er Xian Tang with one of the following:

• Warm the Cockles (Fu Gui Ba Wei Tang)

• You Gui Tang 

• Tao Hong Si Wu Tang when healthy circulation also requires support.

Where dryness, night sweats and depleted body fluids are more prominent, combinations may include:

• Zuo Gui Wan 

• Qi Bao Mei Ran Dan 

• Tao Hong Si Wu Wan (Persica, Carthamus & Dang Gui Combination – BP061) where circulatory support is also indicated.

 

Severe Hot Flushes

When vasomotor symptoms are particularly intense, additional formulas may be selected to improve temperature regulation and provide broader hormonal support.

These commonly include:

• Menopause (Zhi Bai Ba Wei Wan)

• Cool, Calm & Collected (Jia Wei Xiao Yao San) particularly where hot flushes are aggravated by stress, frustration or emotional tension.
