How to treat Hair Loss with Chinese Medicine

 Tiejun Tang

Hair loss is a common condition affecting millions of people worldwide. In the UK, approximately 50% of men over the age of 50 and 50% of women over the age of 65 experience hair loss.[1] Androgenetic alopecia, alopecia areata, and telogen effluvium are the most common types of hair loss. This condition can lead to significant psychological distress and social anxiety. According to the NHS, hair loss is often underreported, and many individuals seek treatment only after the condition has progressed significantly.[2]

Western Medicine Approaches to Hair Loss

Western medicine offers several treatments for hair loss, but their effectiveness is often limited:

1.     Minoxidil: A topical solution that stimulates hair growth by increasing blood flow to the scalp. It requires continuous use to maintain results; stopping treatment leads to hair loss recurrence. It is only effective for a subset of patients, with studies showing significant regrowth in about 30-40% of users. Side effects include scalp irritation, itching, and unwanted facial hair growth in some cases.

2.     Finasteride: An oral medication that inhibits the hormone dihydrotestosterone (DHT), which is responsible for androgenetic alopecia. It is primarily effective for male pattern baldness and is not suitable for women. Side effects include sexual dysfunction, which can persist even after discontinuation (post-finasteride syndrome).

3.     Hair Transplant Surgery: A surgical option for advanced hair loss. This therapy is costly and invasive, carrying risks such as scarring, infection, and unnatural-looking results if not performed well. Additionally, it does not prevent further hair loss in non-transplanted areas.

The Chinese Medicine Approach to Hair Loss

Traditional Chinese Medicine (TCM) views hair loss as a manifestation of internal imbalances, particularly involving the kidneys, liver, and blood. According to TCM, healthy hair growth depends on the abundance of Qi (vital energy) and blood, as well as the proper functioning of the kidneys, which are believed to govern hair health. Common TCM treatments for hair loss include:

Herbal Remedies

 Heshouwu (Polygonum multiflorum):  A popular herb known for its hair-nourishing properties. Studies suggest it promotes hair growth by improving blood circulation and reducing oxidative stress. Research has shown that Heshouwu extract supports hair growth by prolonging the anagen phase and counteracting the effects of androgens in cultured human dermal papilla cells.[3]

Ginseng: Enhances Qi and blood circulation, supporting hair follicle health. Treatment with Red Ginseng Oil (RGO) and its main components has been found to upregulate the expression of hair growth-related proteins, inhibit inflammation and apoptosis, and induce cytoprotective mechanisms, thereby preventing or treating hair loss and protecting the skin from UV radiation.[4]

 Danggui (Angelica sinensis)A commonly used herb for  nourishing blood, it containing glycoside active ingredients mainly promote hair follicle cells to enter the growth phase earlier or inhibit hair follicle cell apoptosis.[5]

 BeauTop (BT): A traditional Chinese medicine compound composed of Ginseng, Angelica, and Astragalus. It has been shown to promote hair growth by increasing the expression of vascular endothelial growth factor (VEGF), which is a key mediator in the angiogenesis process involved in hair growth and development.[6]

 Yangxue Shengfa Capsule (YSC): Clinically used for many years to improve androgenetic alopecia (AGA). Studies have demonstrated that five of its compounds significantly promote cell proliferation in cultured immortalized human dermal papilla cells. Ferulic acid and rhamnolide have shown promising pharmacological properties against AGA.[7]

Acupuncture

Acupuncture stimulates specific points on the scalp to improve blood flow and balance Qi. Research has shown that acupuncture can be effective in treating alopecia areata.[8]

Conclusion

Hair loss is a multifaceted condition with significant psychological and social impacts. While Western medicine provides effective treatments, these often come with limitations, including suboptimal results for some patients, side effects, and high costs.

Traditional Chinese Medicine, on the other hand, aims to address the root causes of hair loss by harmonizing Qi and blood, regulating internal organ function, and taking a multi-target approach. This holistic strategy results in a stable and lasting therapeutic effect.

How to Treat Osteoarthritis with Chinese Medicine

 Tiejun Tang

Osteoarthritis (OA) is the most prevalent form of arthritis globally, affecting approximately 7.6% of the population—equivalent to around 595 million people as of 2020. The knee is the most commonly affected joint, followed by the hip and hand.[1] In the United Kingdom, OA is a significant health concern, with an estimated 10 million people living with the condition. Among these, 5.4 million are affected by knee OA and 3.2 million by hip OA. Notably, approximately 18% of individuals over 45 in England have been diagnosed with knee OA.[2]

Western medicine primarily focuses on managing OA symptoms rather than curing the disease. Common treatments include:

1.    Pharmacological Interventions: Nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen, and corticosteroids are commonly prescribed to reduce pain and inflammation. However, long-term use of NSAIDs can lead to gastrointestinal, cardiovascular, and renal complications.

2.    Physical Therapy: Exercise and physical therapy are recommended to improve joint function and strengthen surrounding muscles. While effective, these methods require consistent effort and may not be suitable for all patients.

3.    Surgical Interventions: In severe cases, joint replacement surgery may be necessary. Although surgery can provide significant relief, it is invasive, costly, and carries risks such as infection and prolonged recovery.

4.    Lifestyle Modifications: Weight management and activity adjustments are often advised to reduce stress on joints. However, these measures are not always sufficient to control symptoms.

          Despite these options, many patients continue to experience pain and disability, highlighting the need for alternative or complementary therapies.

Traditional Chinese Medicine Approach to Osteoarthritis

Traditional Chinese Medicine (TCM) views OA as a manifestation of imbalances in the body, particularly involving the deficiency of liver, kidneys, and spleen. According to TCM theory, OA is often associated with "Bi syndrome" (obstruction syndrome), which arises when wind, cold, and dampness invade the body, blocking the flow of Qi (vital energy) and blood in the meridians. This blockage leads to pain, stiffness, and reduced mobility.

TCM treatments for OA aim to restore balance and promote the free flow of Qi and blood. Common approaches include:

1. Chinese Herbal Medicine

Duhuo Jisheng Decoction (DHJSD): This ancient prescription, attributed to Sun Simiao (581–682 AD) of the Tang Dynasty, is widely used in China to treat early-stage knee OA. Recent studies have shown that DHJSD: Increases the synthesis of chondrocyte autophagosomes and the expression of autophagic proteins (LC3 and Beclin-1).Reduces the phosphorylation levels of Akt and mTOR, as well as the levels of zinc, MMP-13, Bax, and Bcl-2.Inhibits the Akt/mTOR signaling pathway, promotes chondrocyte autophagy, and has a protective effect on cartilage.[3]

Additionally, DHJSD has been found to antagonize the production of proinflammatory cytokines in human nucleus pulposus cells (hNPCs) induced by SDF-1. This suggests that DHJSD may inhibit inflammation by targeting multiple molecules in the SDF-1/CXCR4/NF-κB pathway.[4]

The latest research in 2025 confirmed that DHJSD can repair cartilage damage in rabbits and reverse the level of inflammatory factors in joint fluid. Its therapeutic mechanism is related to the activation of TGF-β/Smad signaling pathway. This provides a reliable basis for the application of DHJSD in the treatment of cartilage damage after knee osteoarthritis.[5]

2. Acupuncture

Acupuncture is a well-studied TCM modality for OA. A clinical study involving 442 patients with knee OA compared electroacupuncture (EA)manual acupuncture (MA), and sham acupuncture (SA). The results showed that the remission rates in the EA and MA groups were significantly higher than in the SA group.[6]

3. Moxibustion

Moxibustion, a therapy that involves burning mugwort near the skin, has also shown promise for OA. A meta-analysis of 57 randomized controlled trials (RCTs) involving 5,149 subjects found that moxibustion and combined moxibustion therapies improved the overall effectiveness of knee OA treatment.[7]

4. Tuina (Therapeutic Massage)

Tuina, a traditional Chinese therapeutic massage, has been reported to: Reduce knee OA cartilage tissue damage.Decrease inflammatory response and chondrocyte apoptosis.Activate the PI3K/AKT/mTOR signaling pathway, which may contribute to its therapeutic effects.[8]

Conclusion

Osteoarthritis is a widespread and debilitating condition that poses significant challenges to patients and healthcare systems worldwide. While Western medicine provides valuable tools for managing OA, it has limitations and potential side effects. TCM offers a promising complementary approach, with mechanisms of efficacy increasingly supported by scientific research. By combining the strengths of Western and Traditional Chinese Medicine, we can provide more comprehensive and effective treatment options for osteoarthritis patients globally.

Chinese Medicine for Eczema: A Holistic Approach to Skin Health

 Tiejun Tang

Eczema, a chronic inflammatory skin condition characterized by dry, itchy, and inflamed skin, is a growing concern in the UK. According to the National Eczema Society, over 15 million people in the UK suffer from eczema, with 1 in 5 children and 1 in 10 adults affected.[1] The condition not only impacts physical health but also significantly affects mental well-being and quality of life. While Western medicine offers various treatments, many patients seek alternative therapies, such as Chinese medicine, to manage their symptoms effectively and holistically.

Western Medicine for Eczema: Challenges and Limitations

Western medicine primarily treats eczema with topical corticosteroids, emollients, and antihistamines to reduce inflammation, moisturize the skin, and relieve itching. In severe cases, systemic immunosuppressants or biologics may be prescribed. While these treatments can be effective, they often come with limitations and side effects. Prolonged use of topical steroids, for example, can lead to skin thinning, discoloration, and tolerance, while systemic treatments may carry risks of immune suppression or organ toxicity.[2] These challenges have led many patients to explore complementary and alternative therapies, especially traditional Chinese medicine (TCM).

Chinese Medicine’s Understanding of Eczema

In Chinese medicine, eczema is often attributed to an imbalance in the body’s internal environment, particularly involving the Lung, Spleen, and Liver systems. According to TCM theory, eczema is caused by a combination of factors, including:

  • Wind, Heat, and Dampness: External pathogens like wind and heat, combined with internal dampness, are believed to contribute to skin inflammation and itching.
  • Blood Deficiency: Chronic eczema is often linked to blood deficiency, which leads to dry skin and poor nourishment of the skin.
  • Emotional Factors: Stress and emotional imbalances are thought to exacerbate symptoms by disrupting the flow of Qi (vital energy) and blood.

Chinese Medicine Treatment Methods

Chinese medicine employs a holistic approach to treat eczema, focusing on addressing the root cause of the imbalance rather than just alleviating symptoms. Common treatment modalities include:

  1. Herbal Medicine: Customized herbal formulas are prescribed based on the patient’s specific pattern of imbalance. For example:
    • Wind-Heat Pattern: Herbs like Jin Yin Hua (Honeysuckle) and Lian Qiao (Forsythia) are used to clear heat and expel wind.
    • Damp-Heat Pattern: Herbs such as Huang Qin (Scutellaria) and Fu Ling (Poria) help resolve dampness and heat.
    • Blood Deficiency Pattern: Herbs like Dang Gui (Angelica Sinensis) and Shu Di Huang (Rehmannia) nourish the blood and moisten the skin.

Commonly used formulas include Xiao Feng San (Wind-Dispelling Powder) for acute eczema and Si Wu Tang (Four Substances Decoction) for chronic cases.

  1. Acupuncture: Acupuncture is used to regulate Qi and blood flow, reduce inflammation, and relieve itching. Specific points, such as LI11 (Quchi) and SP10 (Xuehai), are often targeted for skin conditions.
  2. Dietary Therapy: TCM emphasizes the role of diet in managing eczema. Patients are advised to avoid damp-producing foods like dairy and sugar while incorporating nourishing foods such as leafy greens and lean proteins.
  3. Topical Herbal Applications: Herbal creams or washes made from ingredients like Ku Shen (Sophora) and Huang Bai (Phellodendron) can soothe itching and reduce inflammation.

Efficacy of Chinese Medicine for Eczema

A Clinical study showed that Xiaofeng San can reduce in total lesion scores in the treatment group of eczema patients. It was significantly better than that in the placebo group at 8 weeks. There were also statistically significant differences between the treatment group and the placebo group in terms of erythema, skin surface damage, itching, and sleep scores. Patients reported no side effects of the treatment.[3]

A meta-analysis study included a total of 662 patients with eczema were included (322 in the experimental group and 340 in the control group). The area and severity index and the remission rate of the treatment group were better than those of the placebo group. The atopic dermatitis score, surface damage score, and sleep score of the treatment group were all improved.[4]

Modern Pharmacological Research on Chinese Medicine

Modern research has begun to validate the mechanisms behind TCM’s efficacy. For example:

  • Huang Qin (Scutellaria) has been found to contain baicalein, a compound with anti-inflammatory and antioxidant properties.[5]
  • Ku Shen (Sophora) contains matrine, which has been shown to inhibit histamine release and reduce itching.[6]
  • Dang Gui (Angelica Sinensis) promotes blood circulation and skin repair through its active compounds, such as ferulic acid.[7]

These findings bridge the gap between traditional knowledge and modern science, providing a scientific basis for the use of Chinese medicine in eczema treatment.

Conclusion

Eczema is a complex condition that requires a multifaceted approach to management. While Western medicine provides effective symptom relief, its limitations and side effects have led many patients to explore Chinese medicine as a complementary or alternative therapy. With its holistic approach, personalized treatments, and growing body of scientific evidence, Chinese medicine offers a promising option for those seeking to manage eczema naturally and effectively.

Don't Ignore Colds and Flu

 Tiejun Tang

Recently, there has been a significant increase in cold and flu cases, with the UK Health and Safety Agency (UKHSA) reporting a drop in flu positivity rates to 17.5% in week 3, up from 21.1% the week before, as of 22 January 2025. However, among children aged 5 to 14, positivity rates rose to 30.7% from 26.8% in week 2.[1] In Scotland, the flu outbreak has been particularly severe, with 168 flu-related deaths reported last week, the highest weekly toll since records began in 2000.

While some may view these illnesses as minor inconveniences, it is vital to understand the potential harm they can cause, especially if left untreated.

Why you shouldn’t ignore a cold

The common cold may seem harmless, but neglecting treatment can lead to complications. For most healthy people, symptoms may resolve on their own. However, for older people and those with chronic conditions such as diabetes, heart disease or respiratory problems, a cold can escalate into more serious problems such as bronchitis or pneumonia. If left untreated, these complications can be life-threatening.

Flu, on the other hand, is more aggressive. Viruses weaken the immune system, making the body more susceptible to bacterial infections. In severe cases, untreated flu can lead to hospitalization or even death from complications such as sepsis or organ failure.

Risks for Vulnerable Populations

Older adults and those with chronic medical conditions are particularly vulnerable to infection. Their immune systems are often weaker, making it harder for them to fight off infection. A simple cold can quickly exacerbate existing health problems, leading to hospitalization or long-term health effects.

For example:                          

Respiratory complications: Symptoms may worsen in people with chronic obstructive pulmonary disease (COPD) or asthma.

Heart strain: Infections increase the workload on the heart, leading to complications in people with heart disease.

Reduced immunity: People with diabetes may have a harder time controlling their blood sugar levels during illness, increasing their risk of further complications.

Role of TCM in Flu Treatment

Traditional Chinese Medicine (TCM) is widely recognized for its holistic approach to treating illnesses, including flu. TCM focuses on restoring balance in the body and boosting the immune system, which can be especially beneficial during flu season.

Some of the advantages of TCM in treating flu include:

Herbal remedies: Herbal formulas such as Lianhua Qingwen[2] and single herb Banlangen[3] can be used to relieve symptoms such as fever, cough and sore throat. These remedies often have antiviral and anti-inflammatory effects.

Personalized treatment: TCM practitioners tailor treatment plans to each patient's specific needs, targeting both symptoms and underlying imbalances.

Supporting recovery: Techniques such as acupuncture and cupping can improve circulation and enhance the body's natural healing process.

Fewer side effects: TCM generally has fewer side effects than some drug treatments and is suitable for people who are sensitive to traditional medicines.

By combining TCM with modern medical practices, individuals can benefit from a more comprehensive approach to flu prevention and treatment.

Self-protection measures

See a doctor promptly: Do not ignore long-term symptoms or worsening of the condition.

Vaccinations: Annual flu and pneumococcal vaccinations can reduce the risk of severe illness.

Maintain good hygiene habits: Wash your hands frequently, avoid crowded places during peak flu season, and wear a mask when necessary.

Boost your immune system: Eat a healthy diet, stay hydrated, and get plenty of rest.

 Conclusion

Colds and flu should not be underestimated, especially for vulnerable populations such as the elderly and those with chronic illnesses. Early treatment and preventive measures can significantly reduce the risks and complications associated with these illnesses. In addition, considering the benefits of TCM may provide an alternative or complementary approach to managing symptoms and enhancing overall health.

Comments on Chinese Medicine Research Papers Published in The Lancet

 Tiejun Tang    

A recent research paper published in the internationally renowned medical journal The Lancet titled "Traditional Chinese Medicine FYTF-919 (Zhongfeng Xingnao Oral Prescription) for the Treatment of Acute Cerebral Hemorrhage: A Multicenter, Randomized, Placebo-Controlled, Double-Blind Clinical Trial" [1] concluded that the efficacy of the traditional Chinese medicine (TCM) prescription, Zhongfeng Xingnao Oral Prescription, was no different from that of a placebo, and it could not improve the functional prognosis, survival rate, or quality of life of patients with cerebral hemorrhage. This conclusion could easily mislead readers into thinking that traditional Chinese medicine is ineffective in treating cerebral hemorrhage, causing a negative impact on the reputation of TCM and provoking strong responses from the TCM community both domestically and internationally.

But is it really true that traditional Chinese medicine is ineffective in treating cerebral hemorrhage? No! The conclusions of this study only show that the specific prescription used in the trial is ineffective, and they cannot be generalized to all traditional Chinese medicines. The main issue with the negative research results lies in the selection of the prescription.

Zhongfeng Xingnao Oral Prescription contains four ingredients: Hongshen, Sanqi, Chuanxiong, and Dahuang. My opinion is using Chuanxiong in the treatment of acute cerebral hemorrhage is fundamentally incorrect.

The Chinese Pharmacopoeia records that Chuanxiong is pungent, warm, and acts on the liver, gallbladder, and pericardium meridians. It is known for promoting blood circulation, dispelling wind, and relieving pain. It is typically used for irregular menstruation, dysmenorrhea, abdominal pain due to lumps, stabbing chest and rib pain, swelling and pain from injuries, and headaches. In clinical practice, Chuanxiong is recognized for its ability to promote blood circulation and remove blood stasis, making it an important medicine for treating headaches. Modern pharmacological studies have confirmed that the main active ingredient of Chuanxiong is ligustrazine. The pharmacological effects of Chuanxiong and ligustrazine have been hotly researched, with over 1,000 articles available on PubMed when searching for "Chuanxiong" or "ligustrazine" (1022 and 1608 papers, respectively). In 2024 lone, there were 96 and 115 studies published on the topic.

Recent studies on Chuanxiong’s effect on coagulation and blood rheology reveal some concerning findings:

  1. One study using network pharmacology found that Chuanxiong can inhibit TF (tissue factor) procoagulant activity and reduce TF mRNA and protein expression in EA.hy926 cells in a dose-dependent manner via the PI3K/Akt/NF-κB signaling pathway [2].
  2. Another study using affinity ultrafiltration mass spectrometry (AUF-MS) identified 21 active components from Chuanxiong, with ferulic acid, chlorogenic acid, and isochlorogenic acid A being potential antithrombin agents. The conclusion was that Chuanxiong is a Chinese herbal medicine with good anticoagulant effects [3].
  3. A third study using a microfluidic chip model of normal and stenotic arteries showed that ligustrazine inhibits platelet aggregation and activation by reducing the binding of von Willebrand factor (vWF) to the GPIb/IX/V complex, partly inhibiting platelet aggregation through the P2Y12-ADP receptor pathway [4].

Ligustrazine has effects such as inhibiting platelet aggregation, dilating blood vessels, reducing blood viscosity, and anticoagulation. It is mainly used in the treatment of ischemic stroke and can be employed for rehabilitation in hemorrhagic stroke. However, it is obviously unsuitable for use in the acute stage of cerebral hemorrhage, as its anticoagulant properties could worsen bleeding.

In contrast, Western medicine uses hemostatic drugs such as aprotinin, 6-aminocaproic acid, and tranexamic acid in treating acute cerebral hemorrhage to correct coagulation dysfunction and prevent the expansion of the bleeding area. Although the clinical effect of hemostatic drugs is not ideal, they remain one of the routine treatments for acute cerebral hemorrhage. The effect of ligustrazine on coagulation is completely opposite to that of hemostatic agents.

Traditional Chinese medicine (TCM) holds that "blood that leaves the vessel is stagnant," and there are indeed reports of using blood-activating and blood-stasis-removing methods to treat cerebral hemorrhage. However, this is generally applied in the recovery period, not in the acute phase. TCM often uses Sanqi (Panax notoginseng), which has both blood-activating and hemostatic effects, in such treatments. The two ingredients, Chuanxiong and Dahuang, in this particular prescription both promote blood circulation, which does not align with the TCM principles of syndrome differentiation and treatment. This discrepancy likely led to the negative research results in the study.

For treating acute cerebral hemorrhage, TCM must follow the principle of syndrome differentiation. For example:

  • Angong Niuhuang Wan clears heat, resolves phlegm, and opens the orifices, suitable for phlegm-heat blocking type stroke.
  • Shenfu Tang is used for yang qi exhaustion syndrome.
  • Shengmai San is used for qi and yin deficiency syndrome.

There is no single prescription that can effectively treat all types of strokes.

Furthermore, scientific research on TCM must respect the inherent principles of TCM. It cannot simply replicate the Western medical research model, as this approach would lead to biased conclusions.

The best reward for my 40 years clinical practice

Tiejun Tang

This year marks the 40th anniversary of my graduation from the University of Traditional Chinese Medicine, which marked the beginning of my career as a TCM doctor and university teacher. 

An International Chinese media and an authoritative academic institution selected 22 The Overseas Grand Master of Traditional Chinese Medicine and 155 Famous Practitioner of Traditional Chinese Medicine in the world. I am very honored to be selected as one of the 22 Overseas Grand Master of Traditional Chinese Medicine. This is the best reward for my 40 years career.

The certificate of the Overseas Grand Master of Traditional Chinese Medicine was received. I would like to thank the selection committee for their excellent work. Unfortunately, due to the time arrangement, I was unable to attend the awards ceremony in Vancouver today. I wish the conference had successfully accomplished.

At this moment, I would like to say a few words to express my feelings from the bottom of my heart:

First of all, I would like to thank my teachers in the past 45 years since I had entered the world of Traditional Chinese Medicine, including all of my teachers in my undergraduate, MSc, PhD and post-doctoral research stages. I would like to thank every alma mater where I studied and worked together for the past years.

Also, I would like to thank the countless of patients that I had treated in China and the UK in the past 40 years. Your suffering is my motivation to keep making progress. Practitioners' knowledge comes from learning, but most of their clinical experience comes from patients’ feedback

I would like to thank my students who based in China, UK and Europe in the past 40 years. Teaching and learning always enhances each other. Being a good teacher and leading my students on the right path is an additional motivating force to continue my journey.

I would like to thank my classmates, colleagues, and friends at all stages who have supported and helped me over the years. 

At last, I would like to thank my family and relatives who have given me a great support all along.

I’m so grateful to have you all in my life.

Precancerous lesions and complementary medicine approach

 TiejunTang 

In recent years, we have often heard bad news about someone who suffers from any type of cancer. According to the statistics of the Cancer Research UK, there are around 375,000 new cancer cases in the UK every year (2016-2018), and around 167,000 cancer deaths in the UK every year (2017-2019). World Cancer Research Fund reported there were 18.1 million cases of cancer diagnosed in 2020 globally.

The prognosis of different cancers are various. Some are completely curable due to the development of medical science; unfortunately some are not. Although they are incurable, we can prevent it. Cancers take time to develop; they often develop from some chronic diseases. These diseases are often called precancerous lesions. If you are being treated appropriately, the condition could be under control.

Below are some examples of common precancerous lesions and the effectiveness of Chinese herbal medicine in these conditions.

1. Atypical Breast Hyperplasia Breast Cancer

Breast cancer is one of the most common cancers, and it often develops from inconspicuous precancerous lesions, such as breast atypical hyperplasia, intraductal papilloma and cystic breast hyperplasia, which are all considered to be precancerous lesions.

From the perspective of traditional Chinese medicine (TCM) , breast hyperplasia is a condition that causes by stagnation of liver qi, which leads to the blockage of qi in the body, resulting in breast pain. TCM herbs that soothe the liver and relieve stagnation can be given to intervene. Commonly used herbs are Xiangfu, Qingpi and Chenpi for soothing the liver and regulating qi. Chishaoyao can be added to activate blood circulation and remove blood stasis, Gualou can be added to resolve phlegm and dissipate stagnation, and Banzhilian & Baihuasheshecao can be added for anti-cancer, as well as reducing the risks of getting breast cancer.

A molecular level experimental study showed: The Chinese herbs Huangqi, Renshen, Fuling and Chaihu, as well as some other herbal formulas can regulate the genetic related and protein expression via pathways such as PI3K/AKT/mTOR, MAPK and Wnt/β-catenin, which inhibits the growth, proliferation, migration, invasion and metastasis of triple-negative breast cancer cell.[1]

2. HPV Infection Cervical Cancer

HPV (human papillomavirus), is divided into high-risk, intermediate-risk and low-risk types according to the risk of causing cervical cancer. Among them, 13 types of viruses are considered in the high-risk category. In the worldwide, there are 90% of cervical cancers are caused by HPV.  In the Western medicine, there isn’t any specific medication for treating HPV, however, It can only be relied on our immunity to cure the disease. In some cases, most of the infections can be healed by themselves within 2 years, however, some patients are potentially suffering from the cervical cancer in the end.

Traditional Chinese Medicine (TCM) believes that this disease is mostly caused by damp-heat, spleen-deficiency, endogenous dampness, as well as toxins which are one of the primary pathologies. Treatment is usually based on strengthening the spleen and removing dampness, clearing away the heat and detoxifying.  The modified formula of the Traditional Chinese medicine, the Simiao Decoction is used in the treatment of HPV, showing the satisfactory efficacy.

The Research shows that the mechanism of Chinese herbal medicine may perform on the regulation of cell apoptosis, viral gene transcription and translation, cell signal transduction pathways and the immune function.[2]

3. Colon Polyps Colon Cancer

Colon cancer is relatively one of the common cancers in the UK, and a large proportion of colon cancers develop from the polyps. Adenomatous polyps have a higher probability of becoming cancerous.  As the size of adenomatous polyps grows, their growth rate is also increased with the total canceration rate ranging from 10% to 20%, therefore, the Western medicine uses endoscopic electrocoagulation resection for the treatment of intestinal polyps, and the recurrence rate is very high.

TCM believes that the causes of colon polyps is due to damp heat, phlegm, and blood stasis that accumulate in the large intestine. The principles of treating this disease are to strengthening the spleen and replenishing the qi, clear away damp heat, and resolve phlegm and blood stasis. In my master degree research in the early 1990s, I applied Jianpi Yikan Pills to treat the intestinal polyps and a satisfactory result was achieved. This patent remedy can be significantly reduced the postoperative recurrence of intestinal polyps.[3]

4. Chronic Atrophic Gastritis Stomach Cancer

For chronic stomachache patient, a gastroscopy is necessary. If the biopsy result of the gastroscopy is chronic atrophic gastritis, We must pay more attention to it, especially if it is accompanied by atypical hyperplasia and intestinal metaplasia, a high risk of stomach cancer is associated.  It is generally believed that the canceration rate is: 3% to 5% in 5 to 10 years, and 10% in more than 10 years. 

TCM believes that the etiology and pathology of atrophic gastritis may include liver and stomach qi stagnation, spleen and stomach deficiency, stomach-yin deficiency or stomach blood stasis. The herb selection should depend on the symptoms of individual cases: Chaihu, Foshou to soothe the liver and relieve the liver qi stagnation ; Dangshen and Baizhu to strengthen the spleen and stomach Qi; Maimendong, Shashen and Shihu to nourish stomach yin;  Chishaoyao and Danshen to remove blood stasis.

Research shows that the mechanism of TCM in treating chronic gastritis include the eradication of Helicobacter pylori, the anti-inflammatory effects, the immune regulation, and the regulation of gastric mucosal cell proliferation, apoptosis, and autophagy levels[4].

5. Pulmonary Nodules Lung Cancer

Chronic cough has increased since the pandemic of COVID-19.  Many people were diagnosed with pulmonary nodules after Covid.  This disease may lead to lung cancer, among which atypical adenomatous hyperplasia which is a type of precancerous lesion.  The bigger the nodule, the higher risk of malignant transformation. People with lung cancer family history are more likely to develop cancer in their lung nodules.

Nevertheless, there is no evidence that pulmonary nodules can be treated by any western medicines, and the surgical operation is necessary for the larger nodules, although the new nodules may reoccur after the surgery.

TCM believes that the main pathogenesis of pulmonary nodules is: deficiency, phlegm, blood stasis, and poison. The treatment principles are to nourish the spleen and lungs, resolve phlegm and detoxify, and dissipate blood stasis and dredge the collaterals.

Usually, Huangqi and Dangshen are used to replenish the qi of the spleen and lungs; Banxia, Qianhu, Zhebeimu and Gualou are used to resolve phlegm and relieve cough, Banzhilian and Yuxingcao are used to clear away heat and detoxify; Sanqi and Danshen are used to activate blood circulation and remove blood stasis.

The Molecular biology and pharmacology research shows that the traditional formula, QianJin WeiJing decoction (QJWJ) can inhibit the growth of lung cancer A549 cell line in a time-dependent manner, which may inhibit the growth of lung cancer cells by inhibiting EGFR and STAT3 signaling pathways, and arresting the cell cycle in G0/G1 phase. The other research showed QJWJ can induce apoptosis in lung cancer cells and enhancing immunity in lung cancer patients. [5]

6. Cirrhosis Liver Cancer

Viral hepatitis is a very common disease in China. In about 10-30% of chronic hepatitis B patients develop cirrhosis within 5-10 years, besides, 5-10% of cirrhosis patients develop liver cancer within 5-10 years as well.  Cirrhosis is considered as a precursor to liver cancer. Although viral hepatitis is relatively rare in the UK, alcoholic cirrhosis becomes the risk factor of liver cancer.

TCM has accumulated immeasurable clinical experiences in treating chronic liver diseases over thousands of years. For those with hypochondriac pain and swelling pain, Chaihu, Qingpi, and Chunlianzi can be used to promote qi and relieve pain; for jaundice conditions, Yinchen, Dahuang and Zhizi can be selected to clear away damp heat and relieve jaundice; for ascites conditions, Fuling, Zexie, Dafupi can be added to diuretic and expel dampness; for patients with hepatosplenomegaly, Danshen, Sanleng, Ezhu can be given to promote the blood circulation and remove blood stasis, or Guiban and Biejia can be used to soften the hardness; for those with cancer tendencies, Banzhilian and Baihuasheshecao can be added to prevent the occurrence of tumors.

There was a cohort study that counted 127,237 liver cancer patients, of which 30,992 (24.36%) were treated with Chinese herbal medicine. Compared with patients who did not use Chinese herbal medicine, The TCM group showed a significantly lower risk of deathModified Xiaoyao San and Chaihu Shugan San were the most effective formulas for improving survival.  [6]

Most importantly, getting early diagnosis and treatment are the most crucial part, as it has a great impact on the patient’s prognosis.

Paying enough attention to the treatment of precancerous lesions can slow down or stop the canceration of cells and avoid the occurrence of cancer. Clinical practice has proven that traditional Chinese medicine can have advantages to the treatments listed above dedicated to precancerous lesions, and its mechanism of action has been confirmed by a variety of scientific studies.

Be aware of the precancerous lesions and eliminate potential risks of cancer is the right choice of your health.
