A cough can be the result of a number of different causes. Identifying the type of cough and its cause will help in deciding what approach is best in providing relief. Read on to discover more about coughs, what Chinese medicine has to say about them, and herbal and lifestyle support to use to relieve them.


Types of cough

A cough is often described as either ‘wet’ or ‘dry’ to signify whether it’s accompanied by the production of phlegm (also known as sputum). Phlegm can vary in consistency, from clear and watery to thick. A wet (or ‘productive’) cough can be accompanied by other symptoms that vary according to the cough’s cause and duration.1

When a cough is caused by a common cold or flu, additional symptoms may include a sore throat and the presence of mucus that is either expelled from the body during coughing or accumulates causing congestion.2

In some cases, the cough be characterised by dryness - sometimes referred to as unproductive - and can include hacking, without the expulsion of phlegm.2

What causes cough?

Coughing occurs when something irritates the mucous membranes of the airways. Common triggers include common colds and flus, post-nasal drip (in which mucus drips into the throat from the nasal passages), and mild bronchial irritation.

Coughing is something that you can do at will, but it also occurs as a reflexive action – meaning that it occurs automatically (and sometimes without your voluntary control) when your body is attempting to clear your airways –usually in response to some form of irritation. It involves a deep inhalation and subsequent rapid, forced exhalation, which creates the characteristic sound of the cough.

Irritation of the airways prompts the increased production of sputum, which forms on the lining of the membranes in the affected parts of the respiratory tract, triggering cough.


What do the lungs do in Chinese medicine?

In traditional Chinese medicine (TCM), the lung organ-meridian system encompasses not only the lungs themselves, but also the skin and mucous membranes such as the throat and nasal passages. Together these tissues are regarded as the first line of defence against influences from outside the body with the potential to penetrate the body’s surfaces and cause illness.

The lung organ-meridian system is considered responsible for breathing, immune system function and keeping the body’s various fluids in a liquid state in TCM. Importantly, it also plays a key role in the way Qi (vital force energy) is absorbed and transported around the body.

The lungs and coughing

Phlegm may accumulate if the lung organ-meridian is unable to liquefy the fluids in the lungs appropriately, leading to congestion and coughing.

From the perspective of TCM, cough can be thought of as an excess of wind, commonly in combination with excess cold, heat and/or dryness.

Herbal therapies for cough

In both Western and Chinese herbal medicine, there are a number of herbs that can provide relief from the common symptoms of cough. Many of these have an expectorant type action, that is, they help to expel respiratory mucus. Read on to do discover how specific herbs are traditionally used in Chinese and Western herbal medicine, and when to consider each of them.

Diet and lifestyle recommendations for cough

  • It’s a no-brainer, but stop smoking if you haven’t already done so. There are a number of excellent support services and treatment options available to help in quitting smoking
  • Support your defensive Qi by avoiding exposure to excessive wind and extremes of heat or cold. If you need to go out in windy or chilly weather, rug up well and wear a scarf to protect your neck and chest. To support your lung organ-meridian according to TCM, eat foods with warm and pungent flavours such as garlic, onions, ginger and chilli
  • Avoid dairy products and foods that are cool in temperature as they’re traditionally believed to promote the formation of phlegm in TCM
  • Regular exercise helps keep your lungs healthy. From the perspective of TCM, choose gentle, breath-based forms of exercise such as Tai Chi and Qigong. Always talk to your health professional before beginning a new exercise routine
  • In TCM, issues affecting the lung organ-meridian system are sometimes associated with unresolved sadness or grief. If you believe you may be experiencing such issues, ask your healthcare professional for a referral to a counsellor or psychologist
  • If your work exposes you to environmental irritants, take every possible step to protect your lungs, including wearing a face mask and using an extraction fan where possible
