Key Takeaways

Traditional Chinese Medicine (TCM) addresses persistent coughs by first examining symptom patterns, environmental factors, and an individual’s constitution.
Coughs are either induced by external pathogens or caused by internal imbalances.
TCM remedies for cough include Acupuncture, herbal formulas, Food Therapy (食疗), and tech-enhanced therapies such as Cell Pro Therapy (CPT) and Electro-Lymphatic Therapy (ELT).

Understanding the Root of a Lingering Cough

A lingering cough that doesn’t seem to go away can be more than just an annoyance, affecting sleep, concentration, and overall quality of life. While over-the-counter options may provide short-term relief, ongoing symptoms are an indication of deeper imbalances that require further attention. In this article, we explore common causes of persistent cough and how Traditional Chinese Medicine (TCM) approaches cough to support your recovery.

What is Considered a Persistent Cough?

In Western medicine, a cough that lasts longer than eight weeks is typically classified as chronic^[1]. In TCM, however, the diagnosis of a cough also considers other factors, such as:

The nature of the cough
Environmental influences
Characteristics of phlegm
The individual’s constitution

By taking these elements into consideration, TCM offers a holistic framework for understanding persistent cough. Identifying whether the cause is largely internal or external can also guide the choice of supportive therapies.

Types and Causes of Cough in TCM

1. Cough Induced by External Factors (外感咳嗽)

In TCM, certain types of cough can be caused by or linked to external environmental influences such as Wind, Cold, Heat, and Dryness. Coughs of this nature often develop suddenly and may vary in presentation depending on the specific trigger.

Common patterns include:

Wind-Cold Cough: Often presents with symptoms like chills, aversion to cold, and clear or white phlegm. It may occur more frequently in air-conditioned environments or during colder seasons^[2].

Wind-Heat Cough: This type of cough may come with a sore throat, thick or yellow phlegm, and low-grade fever. It is commonly associated with exposure to warm or humid environments^[2].
Wind-Dryness Cough: Characterised by a dry, scratchy cough with little or no phlegm. This is sometimes observed during hazy periods or in environments with low humidity^[2].

TCM treatments for externally induced coughs usually aim to address the external influences and support respiratory comfort. Food therapy, for example, is commonly used as a complementary approach. Some recommendations include:

Snow fungus and pear soup, which moistens the lungs and dispels heatiness^[3]. This makes it particularly suitable for Wind-Dryness coughs.
Chrysanthemum tea for Wind-Heat cough due to its ability to clear heat and detoxify the lungs^[4].

2. Cough Caused by Internal Imbalances (内伤咳嗽)

Coughs stemming from internal imbalances often develop slowly and are more likely to become chronic. These may involve factors such as imbalances in the Lungs, the accumulation of phlegm and Dampness, or a deficiency in Yin.

They may present as:

Damp-Heat Cough:
Associated with thick, yellow phlegm that may be tough to expel. This pattern is common in hot, humid climates^[5] like Singapore’s, or after the consumption of rich or oily foods.
Liver-Fire Cough:
Characterised by sudden coughing spells and minimal phlegm. This type of cough is often associated with periods of high stress or irritability^[5].
Lung Yin Deficiency:
A dry cough with little or no phlegm, often experienced during recovery from illness or in individuals with naturally dry constitutions^[6].
Phlegm-Damp Cough:
Typically presents with a chronic, lingering cough accompanied by sticky, white phlegm that feels difficult to fully clear. Symptoms may worsen in humid environments or after consuming cold, sweet or greasy foods, as these can further contribute to Phlegm and Dampness accumulation in the body^[7].

TCM for chronic cough focuses on restoring internal balance and supporting the body’s own healing processes. Common therapies include:

Acupuncture
Fine needles are inserted into the body at specific acupoints to help regulate Organ systems, promote the flow of Qi, and enhance circulation. In TCM, smooth Qi flow and improved circulation help with chronic cough because they restore balance in the Lungs, disperse stagnation and support the body’s ability to expel phlegm and pathogens.
Cell Pro Therapy (CPT)
CPT involves the delivery of reducing electrons through the skin to support cellular activity. By supporting cellular metabolism, it helps the body defend against daily stressors, restore internal balance, and support immune function^[8]^[9].
Electro-Lymphatic Therapy (ELT)
ELT is a non-invasive method designed to improve lymphatic circulation. Enhanced lymphatic flow aims to support the body’s natural detoxification processes and immune function. In TCM, ELT may be used in conjunction with other TCM therapies for cough, such as acupuncture and herbal medicine^[10].
Herbal Medication

TCM physicians may also customise herbal formulas based on the individual’s symptoms, pulse, and tongue diagnosis. These prescriptions are designed to address the root imbalances and support Lung function. Some commonly prescribed herbs for cough include:

Dried Tangerine Peel (陈皮): This herb is known to relieve coughs associated with Phlegm-Damp obstruction in the Lungs. It helps regulate Qi, dry Dampness and support the body’s natural process of clearing phlegm, making it suitable when a cough feels heavy or congested.
Semen Armeniacae Amarum (杏仁): Also known as bitter apricot seed, it is a classic herb in TCM used to relieve cough and wheezing. It works by directing Lung Qi downward hence stopping cough, and moistening the intestines.
Lily Bulb: Particularly known for replenishing Yin and moistening the Lungs. It is considered excellent for dry coughs, sore throats and a general feeling of dryness in the respiratory system.
