Pertussis, widely known as whooping cough, is a bacterial infection caused by Bordetella pertussis. This respiratory ailment is especially notorious for its intense, unrelenting coughing fits that can culminate in a characteristic whooping sound during inhalation.
It's particularly severe in infants and young children and starts with symptoms akin to a common cold before progressing to more pronounced and severe coughing episodes.
TCM Perspective on Pertussis
From the viewpoint of Traditional Chinese Medicine (TCM), pertussis is perceived as a disruption of Qi, the vital life energy, predominantly in the Lung region. This disruption is often attributed to external pathogenic factors such as Wind, which invades the Lungs, resulting in an imbalance and manifesting as the severe cough associated with pertussis.
TCM treatment strategies revolve around expelling these external pathogens, restoring Qi balance, and reinforcing the body's innate defenses against such external factors. The unique aspect of TCM lies in its approach to identify and rectify the specific pattern of disharmony underlying each case.
TCM identifies various patterns of disharmony as potential causes behind pertussis. A common pattern is Lung Qi Deficiency, where the lung's capability to distribute and lower Qi is compromised, leading to symptoms like severe coughing.
Another pattern could involve the invasion of Wind-Cold or Wind-Heat, disrupting Lung functionality. Phlegm accumulation is also considered a significant factor in TCM, as it can obstruct Lung Qi, contributing to the severity of coughing spells. The emphasis in TCM treatment is on identifying these individual patterns in patients and tailoring the treatment accordingly, which may include herbal remedies and acupuncture.
TCM Patterns for Pertussis
Each pattern represents a distinct underlying imbalance that can cause pertussis
Heat invading the Pericardium
Diagnostic signs
Fine (Xi), Rapid (Shu), Wiry (Xian)
The tongue is typically deep red or crimson (绛色), reflecting Heat at the Ying or Blood level. The body is often stiff, making it difficult for the patient to protrude the tongue. In severe cases, prickles or thorns may appear on the tip, indicating intense Heart-Pericardium Fire. The coating is usually yellow and dry, or may be scanty to absent as Heat consumes fluids. The tip of the tongue, which corresponds to the Heart, tends to be the most intensely red area. In some cases, the tongue may appear curled or shortened due to the Heat contracting the sinews.
Wind-Heat entering the Lungs
Diagnostic signs
Floating (Fu), Rapid (Shu)
The tongue body is typically a normal pink-red colour overall, but with a notably red tip. The tip of the tongue corresponds to the upper body (Heart and Lungs) in tongue diagnosis, so redness here specifically reflects Heat affecting the Lungs and the upper burner. The coating is thin and yellow, indicating Wind-Heat that has not yet penetrated deeply. In very early stages, the coating may still appear thin and white before transitioning to yellow as the Heat becomes more established. The edges may also show slight redness.
Lung Yin Deficiency
Diagnostic signs
Fine (Xi), Rapid (Shu), Floating (Fu), Empty (Xu)
The tongue is characteristically red and dry, often appearing slightly thin or shrunken due to fluid depletion. The coating is typically scanty or absent entirely, sometimes presenting as a 'mirror tongue' (glossy with no coating at all) or a geographic/peeled pattern where patches of coating are missing. The front portion of the tongue (corresponding to the Lung area) may be particularly dry or show small red spots. Cracks on the tongue surface, especially in the central area, reflect long-standing fluid depletion. In milder or earlier cases, there may still be a thin white coating but with notably reduced moisture.
Stomach Yin Deficiency
Diagnostic signs
Fine (Xi), Rapid (Shu)
The classic tongue for this pattern is red with little or no coating, and notably dry, especially in the centre. The centre of the tongue corresponds to the Stomach area, and this is often where dryness and coating loss are most prominent. In early or mild stages, the coating may still be present but appears rootless, as though resting on the surface rather than growing from the tongue body. As the condition progresses, the coating peels off in patches (geographic tongue), and in more advanced cases the entire tongue may be bare and mirror-like. Cracks may develop in the central area, reflecting deeper fluid depletion. The overall tongue body tends to be thin rather than swollen, reflecting the drying and wasting nature of Yin Deficiency.
Diagnostic signs
Deep (Chen), Wiry (Xian), Slippery (Hua)
The tongue typically shows a pale, slightly puffy body with a slippery white coating, reflecting the cold, fluid-retaining nature of this pattern. In the early stage when external pathogenic factors are involved, the coating may be thin and white. As fluid accumulates, the coating becomes white and greasy or slippery. In some cases with Heat developing during the initial invasion phase, the coating may have a slight yellow tinge. Teeth marks on the edges reflect underlying Spleen Qi weakness. The tongue body is moist or wet rather than dry, consistent with the retention of pathological fluid.
