Rosacea

Understanding Rosacea

The tradition describes rosacea through heat, specifically heat that builds in the Stomach and Lungs and travels along the channels that end in the face.

Because the Stomach channel runs to the nose and cheeks, excess Stomach heat from spicy food, alcohol and rich meals is said to flush the face directly. The result is redness and flushing that worsens after eating or drinking, with thirst and a dry mouth.

Where heat has been present for a long time, Toxic-Heat develops: red inflamed papules and pustules on top of the flushing, with burning, thirst and constipation.

In long-standing cases the picture changes again, to Qi and Blood stagnation, described as thickened bumpy skin on the nose with a purplish-red colour, enlarged pores and fixed tenderness. The classical literature treats this as the late stage of the same process.

The organising idea is that heat moves upward and the face is where it arrives. The Stomach channel runs to the nose and cheeks, so heat gathered in the Stomach from hot spices, alcohol and heavy meals has a direct route to the skin, which is why a heavy dinner can redden the face within an hour. The Lungs matter for a different reason: they have charge of the skin and the nose is their opening, so heat held there, whether from smoke, a lingering chest complaint or long strain, also escapes through the face. Early rosacea is read as the two together.

If that heat is not cleared it changes character rather than simply increasing. The tradition describes it becoming toxic, and toxicity is what produces the inflamed papules and pustules that make rosacea look like acne, with burning, thirst and constipation. The tongue reddens and takes a thick yellow coat, and the pulse becomes slippery and rapid. Months or years of this leave a further trace, because heat that persists congeals the movement of Qi and Blood in the small vessels of the nose, and the skin grows thick, takes a purplish-red tone and turns bumpy or nodular.

That progression explains why treatment is staged rather than fixed. One person's redness settles with cool food and a break from alcohol; another needs the toxicity resolved before anything changes; a third needs the stagnation moved before the nose softens at all. The classical literature treats these as one process at different points, and expects the formula to be revised as the skin moves from flushing to papules to thickening.

How it connects

Rosacea often appears alongside digestive symptoms such as acid reflux, bad breath, a sensation of Heat in the abdomen and a bitter taste in the mouth, because they share a root in Bright Yang Stomach Heat. That pattern arises when Heat accumulates in the Stomach, often from spicy food, alcohol or emotional stress: the Heat rises along the Stomach channel to the face, causing redness and flushing, while disturbing the Stomach's descending function and leading to reflux and a bitter taste. When the Heat intensifies into Toxic-Heat, the skin may erupt with pustules and the digestive symptoms worsen with constipation and foul breath. Treating the Stomach Heat at its root often relieves skin and digestion together. Rosacea also clusters with emotional tension: Liver Qi stagnation from stress and frustration generates Heat that rises to the face, so flushing often worsens before a deadline, after an argument or when sleep is poor, and the person may notice irritability, sighing and a tight chest alongside the redness. When Stomach Heat and Liver Heat combine, spicy food and alcohol can set off a flush within minutes, while the pustular form tends to follow the same digestive pattern. This is why treatment that clears Stomach Heat and settles Liver Qi can calm the skin, the digestion and the mood together rather than treating the face in isolation.

How it is assessed

Diagnosis looks at what triggers the flushing, and whether papules, pustules or thickening have appeared.

What a practitioner looks for

• Triggers: flushing after spicy food, alcohol or hot drinks supports Stomach heat.
• Lesion type: papules and pustules on a red base point to Toxic-Heat; thickening and bumpiness to stagnation.
• Systemic signs: thirst, dry mouth, constipation and irritability support the heat patterns.
• Duration: long-standing redness with skin thickening is read as stagnation rather than active heat.

The practitioner reads the stage from the skin and then confirms it from the rest of the body. Redness that comes and goes, arriving after spicy food or alcohol and settling again, with thirst, a dry mouth and a sluggish bowel, is placed in Bright Yang Stomach Heat. The tongue is expected to be red, with a coat that is thin and slightly yellow, and the pulse rapid, possibly floating or wiry. That combination is read as excess heat climbing the Stomach channel rather than as a problem of the skin alone.

When the redness becomes fixed and acne-like papules or pustules appear with a distinct burning, the reading moves to Toxic-Heat; the tongue is redder with a thicker, yellower and greasier coat, and the pulse slippery and rapid. Where the nose has thickened, become bumpy or bulbous and taken a purplish-red colour, the pattern is Qi and Blood Stagnation, with a dark red or purple-spotted tongue and a choppy or wiry pulse. The classical literature reads that last change as structural, which is why it is expected to respond slowly and why the history of the redness matters as much as its present appearance.

TCM patterns in Rosacea

Three patterns are set out, and they mark stages of one process. In the first, Bright Yang Stomach Heat, the face flushes and reddens, particularly after spicy food, alcohol or a hot drink, with heat that has dried the fluids: thirst for cold drinks, dry lips, a red tongue with a yellow dry coat and a surging pulse at the right middle position. In the second, Toxic-Heat, the heat has become sharper: redness with inflamed papules and pustules, burning skin, intense thirst, dark scanty urine, a redder tongue with a dry yellow coat and a rapid, forceful, slippery pulse. The third, Qi and Blood Stagnation, is the late picture, where months of heat have congealed the flow in the nose: thickened bumpy skin, a purplish-red colour, enlarged pores, fixed tenderness and a wiry, choppy pulse. Because they follow one another, two may appear at once, and the formula follows whichever dominates.

Treatment approach

How the tradition treats rosacea, with the herbs, formulas and points used for it.

Principles

• Clear Stomach heat and cool the Blood while the pattern is active flushing.
• Resolve toxicity when papules and pustules appear.
• Move Qi and Blood in the late, thickened stage, where clearing alone is no longer enough.
• Avoid the dietary triggers the classical literature names: alcohol, spicy food, coffee and rich fried meals.
• One thread runs through every stage: heat is cleared from the face and from the organs that supply it. What changes is the method. Simple heat is cooled and drained downward; toxic heat needs stronger detoxifying herbs added; stagnation needs Blood moved and hardness softened, because clearing alone will not shift tissue that has already thickened. The classical literature also relies on a small set of points across all three patterns, Yingxiang (LI-20), Quchi (LI-11), Hegu (LI-4) and Zusanli (ST-36), with further points chosen for whichever pattern is dominant.

What to expect

• Flushing and papules are described as improving within weeks once the heat pattern is treated and triggers are removed.
• Skin thickening responds slowly, if at all, and is described as the least reversible stage.
• Ongoing dietary care is treated as part of maintenance.
• Most people notice the face feeling cooler and reacting less within the first few weeks, with flushing episodes becoming shorter and less intense and bumps flattening gradually. The classical literature also expects change away from the face, in digestion, sleep or stress, because the same heat is being addressed. Treatment usually begins with a daily formula and needling once or twice a week, and as the skin steadies the sessions are spaced out and the herbs adjusted or stopped. Thickened skin is the slowest element and is not promised a quick result.

Safety and when to get help

For anything severe, sudden or spreading quickly, read when a skin problem needs urgent care.

Cautions

• Do not apply strong topical preparations to inflamed facial skin without advice.
• Prescribed topical or oral treatment should not be stopped abruptly.
• Rosacea affecting the eyes needs medical assessment, not herbs alone.

Using this alongside conventional care

• TCM is described as complementary to conventional care: prescribed topical and oral treatment can continue alongside herbs and acupuncture, and eye involvement needs ophthalmological care.
• Topical gels and creams can be used alongside herbs and needling without difficulty, and the classical literature sees no direct conflict with oral antibiotics either, though it suggests taking the herbs at a separate hour so that digestion is not asked to handle both at once. Blood-moving herbs such as Tao Ren and Hong Hua need to be declared to a practitioner when anticoagulants are in use. Prescribed treatment is never stopped abruptly, and any reduction is made with the doctor as the skin improves.

Diet and lifestyle

• Avoid food and drink that heat the body: spicy dishes, alcohol, coffee, fried and greasy food and excess red meat. Cooling, moistening foods are favoured.
• The dietary rule is simple to state and takes discipline to follow: remove what heats the body. Alcohol, coffee, spicy dishes, fried or greasy food and a heavy intake of red meat are the named offenders. What replaces them is cooling and moistening: cucumber and pear, mung bean and watermelon, bitter greens, chrysanthemum tea. The classical literature adds regular, moderate meals so the Stomach is not overwhelmed, room-temperature water rather than iced drinks, protection from sun and wind, and enough calm that stress does not send heat upward. In the stagnant stage, small amounts of hawthorn and turmeric are suggested to help move Blood.

If you're pregnant

Treatment in pregnancy avoids anything that strongly moves Blood or purges downward. Tiao Wei Cheng Qi Tang is not used because it contains Da Huang, which drives the bowel and is regarded as unsuitable in pregnancy, and Xue Fu Zhu Yu Tang is avoided because Tao Ren and Hong Hua carry a risk of miscarriage. Diet and needling are the usual alternatives: Yingxiang (LI-20) and Quchi (LI-11) may be used gently, without strong stimulation, and mild teas such as chrysanthemum or honeysuckle can cool the heat. A practitioner experienced in pregnancy care should make the decision.

Any redness that spreads, blisters or comes with fever needs medical review rather than self-treatment.

If you're breastfeeding

Bitter-cold herbs such as Huang Lian can pass into milk and cause loose stools or colic, so formulas built around it, Huang Lian Jie Du Tang among them, are used with caution and only with professional guidance. Milder options such as Jin Yin Hua and Lian Qiao are considered safer. Needling is described as safe during feeding because there is no drug to transfer, and dietary change, with cooling foods such as cucumber, mung bean and pear, can do a good deal of the work on its own.

If treating a child

Rosacea is rare in children, and when it appears it is usually a mild flushing provoked by dietary heat or by fever. The Bright Yang Stomach Heat pattern may be present, but herbs are used at between a quarter and a half of the adult dose and only under supervision. Older children generally tolerate needling, with fewer needles and a gentler technique. Correcting the diet, in particular removing spicy and greasy food, is the first line and is often enough on its own.

If treating an elderly patient

In older patients rosacea more often presents as the chronic, thickened type, so Qi and Blood Stagnation dominates. Yin deficiency is also common at this age, so a purely blood-moving formula such as Xue Fu Zhu Yu Tang may need modifying to avoid over-drying the skin. Doses are reduced to about two thirds of the adult standard. Polypharmacy matters here because blood-moving herbs can interact with anticoagulants, which makes needling an attractive option, and warm compresses with gentle facial massage can help, provided the skin is handled carefully.

Urgent-sign guidance is based on standard sources: NHS anaphylaxis, NHS cellulitis, NHS Stevens-Johnson syndrome, NHS melanoma.

Evidence

Research is growing but limited in quantity and quality. Small randomised trials suggest acupuncture reduces facial flushing and papule and pustule counts, with effects comparable to topical metronidazole, and a 2020 meta-analysis of acupuncture for rosacea found moderate evidence of benefit while noting high risk of bias in many included studies. Huang Lian Jie Du Tang shows anti-inflammatory and antimicrobial effects in laboratory work, and Chinese clinical trials report improvement.

Research is growing but still limited in both size and quality. Small randomised trials report that acupuncture reduces flushing and the count of papules and pustules, with results described as comparable to topical metronidazole, and a 2020 meta-analysis found moderate evidence of benefit while noting a high risk of bias across many of the studies pooled. Laboratory work on Huang Lian Jie Du Tang has demonstrated anti-inflammatory and antimicrobial activity. Trials published in Chinese describe less redness and fewer lesions. The reference's own conclusion is that double-blind, placebo-controlled work is still needed.
