An itchy rash that keeps flaring often means eczema, not only dry skin. Herbs, named creams, and acupuncture usually fit once the stage is named.
In brief
An itchy rash that keeps flaring is eczema (湿疹, also called atopic dermatitis, 异位性皮炎). It is among the most common skin conditions in Singapore. Genes, a weaker skin barrier, immune dysfunction, and the environment sit underneath. TCM reads Wind-Dampness-Heat (风湿热): spicy or oily food taxes the Spleen and Stomach, Dampness-Heat gathers under the skin, and external Wind sparks the itch. Stages describe lesion severity, not a one-way timeline: acute damp-heat, subacute Spleen-damp, chronic Blood-deficiency Wind. Clinic care mixes herbs, Huang Lian and Zi Yun creams, acupuncture, and plum-blossom needling. Moisturise often, skip hot showers, and do not stop topical steroids suddenly.
01 · What it is
湿疹 · 异位性皮炎 · atopic dermatitis
An itchy rash that keeps flaring is eczema (湿疹, also called atopic dermatitis, 异位性皮炎). It is among the most common skin conditions in Singapore, and occurrence here is among the highest in the world.
About one in five school-age children and teenagers, and about one in ten adults, live with atopic dermatitis. About a quarter of those adults have a moderate-to-severe form.
02 · Causes
Genes · barrier · immune · environment
Modern medicine names several factors behind eczema. Genes play an important role, as eczema often runs in families. Skin-barrier defects, immune dysfunction, and environmental loads sit alongside that inherited lean.
风湿热 · Spleen · Stomach · Wind
TCM reads eczema as a Wind-Dampness-Heat (风湿热) constitution. People with this irritable lean often over-consume spicy, pungent, or oily foods, which weaken the Spleen and Stomach.
The Spleen and Stomach govern digestion and the conversion of food and drink into the essence that nourishes the body. When they fail to convert that load fully, Dampness-Heat arises. With Wind invading from outside, and Dampness-Heat accumulating beneath the skin, the two forces combine as an itchy rash.
Singapore heaty and oily loads, plus long hours in air-conditioning, often tax the same Spleen picture. See heaty versus cooling for how local foods stack, and the nine constitution types when a damp-heat lean sits underneath.
03 · Stages
Eczema can be read in three stages: acute, subacute, and chronic. The stages describe the severity of the skin lesions rather than a one-way timeline. A rash may start at the subacute stage and move to acute. The same patch may cycle through the stages many times, and it may start or stop at nearly any stage.
| Stage | What the skin shows | Syndrome |
|---|---|---|
| AcuteHeat and damp sit on the surface. | Red, intensely itchy patches, often with leakage | Dampness-heat (湿热证) |
| SubacuteLeakage eases; damp lingers. | Less oozy, still itchy; the barrier is settling | Spleen deficiency with dampness (脾虚湿蕴证) |
| ChronicBlood runs thin; Wind stirs. | Drier, thicker patches and a lingering itch | Blood deficiency with Wind (血虚风证) |
04 · Clinic care
The main principle is to clear heat, eliminate dampness, and relieve the itch. Herbs, named topicals, and acupuncture are matched to the stage after pulse and tongue.
| Method | What it does | When it sits in the plan |
|---|---|---|
| Herbal prescriptionFormulae change with the syndrome. | Clears heat and drains dampness in acute flares; tonifies the Spleen when dampness lingers; nourishes Blood and dispels Wind in chronic patches. | After the stage is named. Not a fixed eczema pack. |
| Topical medicationConcoctions, ointments, or lotions on the lesion. | 黄连膏 (Huang Lian Cream) and 紫云膏 (Zi Yun Cream) are anti-inflammatory ointments used once wound leakage decreases. Chronic patches may use anti-itch lotions. | Subacute lesions often take Zi Yun Cream. Huang Lian Cream sits when the wound is drier. The formula follows the stage. |
| AcupunctureHair-thin needles at points and around lesions. | Moves qi and blood, clears heat, eliminates dampness, and relieves itching. Plum-blossom needles can be used at the lesion sites for itch. | Alongside herbs for acute and chronic pictures. Plum-blossom needling is local, at the rash. |
Pattern formula
Custom prescriptions clear heat, drain dampness, tonify the Spleen, or nourish Blood after the stage is named. Formulae change as leakage eases and the itch settles.
Chinese herbal medicine
黄连膏 · 紫云膏
Named TCM ointments sit on the lesion once leakage decreases. Zi Yun Cream is often used in the subacute stage; Huang Lian Cream when the wound is drier. Chronic patches may take an anti-itch lotion.
Qi · local itch
Body points address the internal pattern. Needling around the rash, and plum-blossom needling on the lesion, is used to move qi and blood and ease severe itching.
Acupuncture at PULSE
Clinic care
Bring dermatology notes and the steroid you use. Physicians at 15 clinics can name the stage and match herbs, topicals, and acupuncture.
05 · Skin care
Daily habits sit beside clinic care. Scratching, hot water, and harsh soap all feed the next flare.
Scratching aggravates the eczema and can lead to pigmentation, open wounds, infection, and scars.
Use gentle soaps or soap substitutes instead of ordinary detergents that strip the barrier.
Water hotter than 40°C makes moisture evaporate faster after the shower and increases transepidermal water loss.
Non-steroid moisturisers do not thin the skin. Apply them liberally through the day, including after swimming.
In a dry or cold environment, keep the skin well moisturised so the eczema is less likely to flare.
Wool and linen tend to irritate. Cotton is usually more comfortable on sensitive skin.
Heat, damp, and toxic-heat loads can worsen the itch. Spicy food, seafood, beef, mutton, and spices such as coriander, chives, celery, ginger, onion, and garlic are common flare foods.
| Load | Ease off |
|---|---|
| Heat-inducingFeeds internal Heat. | Spicy food, deep-fried food, beef, and mutton |
| Dampness-inducingTaxes the Spleen. | Dairy, refined sugars, and cold or raw food |
| Toxic heatCommon flare loads. | Shellfish (crabs, prawns), seafood, alcohol, and heavy spices such as garlic, ginger, onion, coriander, chives, and celery |
Topical steroids
Topical steroids can settle a flare. They should not be used without supervision. Ask your doctor before starting or stopping them, and do not stop suddenly.
Urgent signs
These sit outside a typical flare. Seek conventional medical care the same day.
Spreading redness, heat, pus, or fever after scratching or an open wound.
A rash that spreads quickly over large areas of skin.
Swelling of the face or throat, trouble breathing, or a sudden systemic reaction.
06 · Living with it
A pattern-led plan, with daily barrier care, can reduce how often flares return and how hard they hit. Timelines follow the stage, not a single cream.
| Picture | What often shifts | Typical window |
|---|---|---|
| Acute flareItch and redness on the surface. | Itching and redness may ease as heat and damp are cleared. | 1 to 2 weeks |
| Chronic eczemaBarrier and Spleen work underneath. | Repairing the skin barrier and restoring Spleen and Stomach function. | 3 to 6 months of consistent herbs and acupuncture |
小儿推拿 · herbal powders
Children’s digestive systems are more delicate, so a licensed physician prescribes a gentler, customised dose of herbal powders. Paediatric massage (小儿推拿, Xiao Er Tui Na) is a needle-free option used to support immunity and ease skin inflammation.

FAQs
Common questions before you change food, combine care, or book a first visit.
TCM focuses on the internal imbalance rather than only calming the surface, so timelines vary with severity. For acute flare-ups, itching and redness may ease within 1 to 2 weeks. For chronic eczema, repairing the skin barrier and restoring Spleen and Stomach function typically needs 3 to 6 months of consistent herbal medicine and acupuncture.
Yes. Integrative care is common. You do not need to stop Western medicines or topical steroids abruptly, as a sudden stop can trigger a rebound flare. Leave a two-hour gap between oral Western medicines and TCM herbal prescriptions. Tell your TCM physician about any steroid creams or antihistamines you are using.
Acupuncture for eczema is generally well tolerated. Physicians use sterile, hair-thin needles; most people feel a mild aching or tingling (De Qi). Needling is used to move qi and blood, clear trapped heat, drain dampness, and ease severe itching.
From a TCM view, eczema is driven by internal Dampness and Heat. Ease off heat-inducing foods (spicy food, deep-fried food, beef, and mutton), dampness-inducing foods (dairy, refined sugars, and cold or raw food), and common toxic-heat loads (shellfish such as crabs and prawns, alcohol, and heavy spices such as garlic and ginger).
Eczema (atopic dermatitis) is a chronic genetic condition, so there is no definitive cure in either Western or Chinese medicine. TCM is used to push eczema into longer remission by strengthening the Spleen, clearing Dampness-Heat, and naming your triggers, so flares are less frequent and less severe.
Paediatric TCM is used for childhood eczema under a licensed physician. Because children’s digestive systems are more delicate, the physician prescribes a gentler, customised dose of herbal powders. Paediatric massage (小儿推拿, Xiao Er Tui Na) is a needle-free option used to support immunity and ease skin inflammation.
