“Every cold turns into an ear infection.” This sentence, uttered by exhausted parents, sums up one of the most classic cycles in paediatrics: a runny nose in November, an ear infection in December, antibiotics, then start again in January. Chinese medicine reads this cycle not as fate but as a mechanics of terrain: an overloaded Spleen manufactures Phlegm, and that Phlegm rises towards a Lung whose defensive shield is still immature. Understanding this chain gives parents a concrete lever: dry out the terrain instead of chasing each infection.
The recurrent ear infection: neither chance nor fate
Biomedicine knows the profile of the “repeat ENT” child well: an Eustachian tube still horizontal, adenoids sometimes enlarged, immune defences still learning. That explains the point of entry, but not why one child racks up six ear infections in a winter while his brother has none.
TCM supplies the missing piece: the terrain. Two children exposed to the same virus do not produce the same outcome, because the terrain receiving the aggression differs. The relapsing child most often carries an overloaded Spleen producing Dampness, which thickens into Phlegm and congests the upper airways.
The middle ear and the nasopharynx are drainage spaces. When the terrain is dry, mucus circulates and drains away. When the terrain is saturated with Dampness-Phlegm, these spaces become marshland: the slightest external aggression makes them overflow. The ear infection is not “caught”; it is the overflow of a terrain that was already full.
The Spleen → Phlegm → ears chain: the full mechanism
The mechanics unfold in three stages.
Stage one: the Spleen overflows. A child’s Spleen-Stomach transforms cold, greasy, sweet or overly abundant food with difficulty. What is not transformed becomes Dampness. The modern sources are well known: dairy in quantity (especially served cold), fruit juices, sweets, continuous grazing, evening meals that are too large.
Stage two: the Dampness thickens into Phlegm. Stagnant Dampness condenses. The resulting Phlegm has one property: it rises. In TCM the Lung is “the receptacle of Phlegm”: whatever the Spleen fails to transform, the Lung and the airways store. Runny nose, congested throat, adenoids, blocked Eustachian tube: the mucus has taken root.
Stage three: the Wind makes the vase overflow. External Wind (Cold or Heat) penetrates a poorly defended surface. It pushes the stagnant Phlegm into the ducts: the ear blocks, heats, hurts. The ear infection is the end point of a chain whose first link was on the plate.
This is why treating each episode alone does not break the cycle: the ear is emptied, the terrain stays marshy, and the next cold reproduces the same overflow.
The immature Wei Qi: a defence still under construction
The second actor in recurrence is the Wei Qi, the defensive energy circulating beneath the skin and governing the opening of the pores. In children this shield is still being built: the Lung governing it is immature, and the Spleen producing it is fragile.
Weak Wei Qi gives signs parents recognise: the child catches everything going round at school, sweats easily (pores poorly closed), is often pale, and recovers slowly after each episode. The breach is double: the gate is poorly guarded, and the guard is fed by an overloaded Spleen.
The TCM approach therefore does not “stimulate” immunity the way one might take a supplement: it consolidates the Spleen that manufactures Wei Qi and dries the Phlegm congesting the ducts. Both gestures are dietary above all.
The background protocol: dry the Phlegm, consolidate the Spleen
The background programme rests on one simple movement: reduce what produces Phlegm, support what transforms it.
Reduce the Phlegm producers:
- cold, abundant dairy (iced yoghurts, cold milk, large quantities of fresh cheese); warm or cooked dairy (hot milk, stewed fruit) is better tolerated;
- fruit juices, concentrates of liquid sugar and dampness;
- sweets and very fatty foods, which clog the stomach contents;
- evening portions that are too large for a tired Spleen to finish transforming.
Support the Spleen that transforms:
- warm, cooked meals, especially morning and evening: congees, soups, steamed vegetables, stewed fruit;
- flavours that drain Dampness without irritating: a little spring onion or leek in soups, rice and sweet cereals as a base;
- regular mealtimes and finishing before satiety: a child’s Spleen transforms three modest foods better than one large plate;
- morning congee, the foundational dish of Chinese paediatrics: rice simmered long in plenty of water, served warm, which nourishes the Spleen without tiring it.
During the acute episode: the diet lightens further. The principle is the same as for the first 24 hours of a cold: warm, simple, small quantities, warm drinks. An acute episode is not the time to “build up strength” in a Spleen busy fighting the Wind.
Preventing autumn and winter: the seasonal programme
The winning strategy is played out before the season. Chinese tradition treats the terrain in September and October so that December stays calm.
Consolidate before the cold. Late summer and early autumn: two to four weeks of Spleen-strengthening food (congees, sweet vegetable soups, cooked fruit, a little well-cooked meat) to enter winter with better-endowed Wei Qi.
Keep the Phlegm at bay. Through the season: reduce the Phlegm producers (cold dairy, juices, sweets), keep meals warm, and treat the first cold immediately (warmth, rest, lighter eating) before it can overflow the terrain.
Protect the surface. Wei Qi likes regularity: enough sleep, a neck neither overexposed nor overheated, no abrupt hot-cold swings. A light scarf on a cold windy day is no detail: the neck is the gate of Wind.
When diet is no longer enough
Terrain dietetics changes the frequency and intensity of episodes, but it replaces neither the GP nor the ENT specialist. A painful acute ear infection, a perforation, a high fever, hearing loss, or episodes that continue despite terrain work all require medical advice. Equally, dietary change in children should be gradual and without rigidity: you dry out the terrain, you do not put the child on a diet.
