Chinese Medicine for Eczema

By Dr (TCM) Attilio D'Alberto | Traditional Chinese Medicine Practitioner, Wokingham

Eczema (atopic dermatitis) is one of the most extensively studied conditions in modern Chinese medicine — and for good reason. Chinese herbal medicine for eczema has been the subject of multiple Cochrane reviews and randomised trials, several showing results comparable to topical steroids without the skin-thinning, tachyphylaxis, or systemic side effects of long-term steroid use. The 1990s landmark trials at the Royal Free Hospital in London under Dr Ding-Hui Luo first brought Chinese herbal medicine for atopic eczema into mainstream UK awareness, and the evidence has only grown since. In my Wokingham clinic, the typical eczema patient has been through E45, hydrocortisone, betamethasone, and sometimes immunosuppressants, before turning to TCM — and in most cases sees meaningful, durable improvement.

What eczema is

Eczema is a chronic inflammatory skin condition characterised by an impaired skin barrier, immune dysregulation (particularly Th2-skewed cytokines), and alterations in the skin microbiome. The classical signs are itch, redness, dryness, scaling, sometimes weeping or crusting, and over time, lichenification (thickening). It commonly starts in childhood and may persist or relapse throughout life, and it is closely associated with atopic march conditions — asthma, hay fever, food allergies.

Types of eczema

• Atopic eczema — the most common; often family history of atopy.
• Contact dermatitis — irritant or allergic; localised to area of contact.
• Seborrhoeic eczema — scalp, eyebrows, naso-labial folds; greasy scaling.
• Dyshidrotic eczema (pompholyx) — small itchy blisters on hands and feet.
• Nummular (discoid) eczema — coin-shaped patches.
• Stasis eczema — lower legs, associated with venous insufficiency.
• Asteatotic eczema — older adults with very dry skin.

Common triggers

• Soap, detergents, fragrances, fabric softeners.
• Dust mites, pet dander, pollens.
• Food allergens (cow's milk, eggs, peanuts, soy, wheat in some).
• Sweat, heat, occlusion.
• Cold, dry winter air.
• Wool, synthetic fabrics.
• Stress.
• Hormonal change (premenstrual flares are common).
• Some food intolerances and additives.
• Skin infections (Staph aureus colonisation is very common).

The TCM view

In Chinese medicine, eczema is understood as a skin manifestation of internal disharmony — heat, dampness, blood deficiency, wind, or some combination — rather than a purely local skin disease. This explains why topical steroids often help temporarily but eczema returns: the surface inflammation has been suppressed but the internal pattern that produced it is unchanged. The TCM treatment principle is "treat the root and the branch" — work on the skin acutely while correcting the underlying pattern over months.

TCM patterns of eczema

• Wind-heat — acute red, intensely itchy, sometimes weeping eczema. Triggered by heat, stress, contact. Most common in children and in flares.
• Damp-heat — oozing, crusting, inflamed lesions; flexures (cubital, popliteal, neck); worsened by heat and humidity. Associated with digestive imbalance.
• Blood deficiency with wind-dryness — chronic, dry, thickened, scaly, lichenified eczema. Skin parched and itchy without weeping. Common in adults with long-standing disease.
• Kidney yin deficiency with empty heat — dry hot itchy skin worse at night; perimenopausal eczema; night sweats; restless sleep.
• Spleen qi deficiency with damp — sluggish, soggy, recurrent eczema with poor digestion, bloating, loose stools.
• Liver qi stagnation with heat — stress-driven flares, hot temper, premenstrual worsening.
• Toxic heat — severe, infected-looking, painful eczema with fever; medical assessment first.

Most patients present with a mix of two or three patterns, with shifts over the seasons (drier in winter — more blood deficiency picture; weeping in summer — more damp-heat).

Chinese herbal medicine — the workhorse

Internal Chinese herbal medicine is the most effective single TCM treatment for eczema. The Royal Free Hospital trials in the 1990s used a 10-herb formula based on Wu Wei Xiao Du Yin variations. Today's prescribing is pattern-tailored. Core formulas:

• Xiao Feng San — "Eliminate Wind Powder"; the principal formula for wind-heat with damp eczema. The most widely studied.
• Long Dan Xie Gan Tang — for damp-heat with hot, oozing, infected-type eczema, particularly in flexures and genitals.
• Si Wu Tang or Dang Gui Yin Zi — for blood deficiency with wind-dryness; the chronic dry-thickened type.
• Zhi Bai Di Huang Wan — Kidney yin deficiency with empty heat.
• Modified Bu Zhong Yi Qi Tang — Spleen qi deficiency with damp.
• Wu Wei Xiao Du Yin — toxic-heat infected eczema.
• Yin Qiao San (acute) plus Liu Wei Di Huang Wan (chronic) — for paediatric eczema with atopic march features.

Key herbs include Sheng Di Huang, Mu Dan Pi (cool blood); Jin Yin Hua, Lian Qiao (clear heat-toxin); Bai Xian Pi, Di Fu Zi (relieve itch); Cang Zhu, Fu Ling (resolve damp); Dang Gui, Bai Shao (nourish blood); Fang Feng, Jing Jie (expel wind). I prescribe pharmaceutical-grade granules from Sun Ten in Taiwan, individually blended.

Acupuncture for itch and immune modulation

Acupuncture reduces eczema-related itch and modulates the immune response. RCT evidence shows itch reduction comparable to antihistamines in some studies. Mechanisms include central modulation of itch perception, reduction of mast cell activation, and reduction of pro-inflammatory cytokines.

Typical points: LI 11, LI 4, SP 10, SP 6, BL 17, BL 13, ST 36 with auricular points (Lung, Adrenal, Skin, Shen Men). Treatment weekly for 8-12 sessions, then monthly maintenance.

External herbal applications

External herbal washes and creams are commonly combined with internal treatment:

• Cooling washes with Huang Bai, Ku Shen, Bai Xian Pi for hot, weeping eczema.
• Sheng Di Huang and Mu Dan Pi-based ointments for blood-heat dryness.
• Calendula and Centella ointments from European herbal medicine combine well.
• Honey and yoghurt masks can soothe acute flares (test for sensitivity first).

Always patch-test new external preparations and avoid them on broken or infected skin without practitioner advice.

Diet, gut and the skin

The gut-skin axis is real and clinically important in eczema. Practical advice:

• Trial removal of dairy for 4-6 weeks — many adults with eczema improve.
• Trial removal of gluten for 4-6 weeks if other measures haven't helped.
• Reduce sugar and ultra-processed food — drives inflammation.
• Reduce alcohol — particularly red wine and beer.
• Increase oily fish 2-3 times weekly — EPA/DHA reduce skin inflammation.
• Plenty of vegetables and antioxidant-rich foods — colourful plant variety.
• Fermented foods — kefir, yoghurt (if tolerated), sauerkraut, kimchi.
• Identify food triggers — eggs, nuts, soy, shellfish in some patients (allergy testing where indicated).
• For damp-heat — reduce dairy, wheat, alcohol, sugar; favour cooked over raw.
• For blood-deficient dry types — increase blood-nourishing foods: dark leafy greens, beetroot, black sesame, slow-cooked meat.
• Treat any IBS, SIBO or coeliac disease — gut healing often dramatically improves skin.

Supplements with evidence

• Vitamin D3 1,000-2,000 IU — deficiency is common in eczema; correction reduces severity.
• Omega-3 (EPA/DHA, 1-2 g) — reduces skin inflammation.
• Probiotic with L. rhamnosus GG and L. plantarum — particularly useful for paediatric eczema.
• Zinc 15-25 mg — supports skin healing.
• Quercetin 500 mg twice daily — natural antihistamine, mast cell stabiliser.
• Vitamin C 500-1,000 mg — endogenous antihistamine.
• NAC 600 mg — antioxidant; supports glutathione.
• Evening primrose oil 1-2 g — historical use, mixed evidence; some patients find useful.
• Colostrum / immunoglobulins — emerging evidence in atopic eczema.

Lifestyle and skincare

• Use fragrance-free, soap-free emollient washes — Cetraben, Aveeno, Doublebase.
• Moisturise generously and often — at least twice daily, more in winter.
• Lukewarm (not hot) showers, no longer than 5-10 minutes.
• Pat dry, don't rub; apply emollient within 3 minutes.
• Cotton clothing; avoid wool and synthetic fibres next to skin.
• Wash bedding weekly at 60°C if dust mite allergic; use anti-mite covers.
• Keep nails short to reduce damage from scratching.
• Stress reduction — meditation, breathwork; stress is a major trigger.
• Sleep 7-9 hours — sleep deprivation worsens itch.
• Identify and remove environmental triggers — perfume, fabric softener, particular cleaning products.

Combining with conventional treatment

• Topical steroids (hydrocortisone, betamethasone) — useful for acute flares; TCM allows tapering and reducing reliance.
• Topical calcineurin inhibitors (tacrolimus, pimecrolimus) — for sensitive areas.
• Antihistamines — useful for night-time itch; TCM reduces requirement.
• Antibiotics — sometimes needed for infected eczema; TCM continues alongside.
• Dupilumab (Dupixent) — biologic for severe eczema; TCM combines safely.
• Phototherapy (UVB) — useful for some; combines with TCM.

Always tell your dermatologist you are taking Chinese herbs.

Treatment timeline

• Weeks 1-2: sleep often improves first; itch reduces.
• Weeks 2-4: visible reduction in redness and weeping in damp-heat types.
• Weeks 4-8: chronic dry types soften and lichenification reduces.
• Months 2-4: meaningful reduction in flare frequency; topical steroid reliance reduces.
• Months 4-12: for chronic or severe cases, full benefit takes longer; many patients reach a stable baseline that needs only occasional treatment.

Frequently asked questions

Does Chinese medicine really work for eczema?

Yes. Cochrane reviews and multiple RCTs show Chinese herbal medicine reduces eczema severity scores compared with placebo. The Royal Free Hospital trials in the 1990s established this in the UK; subsequent research has confirmed it for both adults and children.

Can my child take Chinese herbs for eczema?

Yes. Paediatric Chinese herbal medicine for eczema has its own evidence base and is widely used. Doses are reduced and formulas adjusted for children. Use a qualified practitioner with paediatric experience.

Will I have to stop my topical steroids?

Not initially. Continue your prescribed steroids while starting TCM. As the underlying pattern settles over weeks to months, you'll need them less, and many patients taper to occasional flare-only use.

How long does Chinese medicine take to work for eczema?

Itch often reduces in 1-2 weeks; visible skin improvement in 4-8 weeks; meaningful reduction in flare frequency over 2-4 months; full benefit in chronic cases over 6-12 months.

Should I cut out dairy?

A 4-6 week trial off dairy is often informative, particularly in damp-heat types and adults with bowel symptoms. Many improve markedly.

Can Chinese medicine help with topical steroid withdrawal?

Yes — TCM is one of the more useful tools for the rebound flares of topical steroid withdrawal syndrome (TSW). Treatment is more intensive and longer than for ordinary eczema.

What about pompholyx (dyshidrotic eczema)?

Often responds well — typically a damp-heat or wind-damp pattern. Internal herbs plus targeted external washes, plus addressing nickel/cobalt sensitivities and stress.
