By Ava Huang, Herbal Science Researcher at QICAOGANGMU | Updated: May 2026 | Reading time: 9 minutes

QICAOGANGMU Caoben Yijun Rugao is a steroid-free herbal cream formulated with five Traditional Chinese Medicine actives for eczema, psoriasis, contact dermatitis, ringworm, and chronic itch. Like any topical treatment, how you use it determines how well it works. This guide covers the correct application technique, patch test protocol, frequency, layering with other products, and the safety considerations that matter for daily long-term use.

Quick reference: how to use QICAOGANGMU

Understanding the formula: five actives, five mechanisms

QICAOGANGMU Caoben Yijun Rugao is based on TCM principles, formulated to address the internal imbalances that manifest as skin discomfort - without the risks of skin thinning, rebound flares, or systemic side effects associated with corticosteroids. Its five natural actives work synergistically:

• 苦参 Ku Shen (Sophora flavescens) - 1.5%: NF-kB inhibition, Th2 cytokine suppression, TSLP reduction. The primary anti-inflammatory driver. PMID 38358770
• 蛇床子 She Chuang Zi (Cnidii Fructus) - 3%: TRPV3 itch receptor desensitisation. Antifungal against Trichophyton rubrum. Synergistic antipruritic with Ku Shen. PMC6151778
• 冰片 Bing Pian (Borneolum Syntheticum) - 2%: Penetration enhancer driving all actives deeper into the skin. TRPA1 inhibition and TRPM8 activation for direct itch relief. PMID 37290679
• 百部 Bai Bu (Stemonae Radix) - 0.5%: COX-2/NO anti-inflammatory. Antibacterial against Staph aureus, which colonises over 90% of eczema-affected skin. PMID 35295975
• 薄荷脑 Bo He Nao (Menthol) - 0.5%: Immediate TRPM8 cold receptor activation within minutes - the fastest itch relief you will feel on first application. PMID 30067875

Step-by-step application guide

Step 1: Wash with plain warm water only

Before each application, wash the affected area with plain warm water only - no soap, cleanser, or pH-balanced product on the inflamed skin. Soap and cleansers can strip the skin's natural oils and worsen barrier dysfunction. Avoid hot water and vigorous rubbing. Pat the skin nearly dry with a clean, soft towel, leaving it slightly damp. Slightly damp skin absorbs topical actives better than dry skin, and Borneolum is most effective when it encounters a hydrated stratum corneum.

Step 2: Patch test (mandatory before first use)

For all users, perform a patch test before widespread application - this is not optional.

• Apply a pea-sized amount of QICAOGANGMU to the inner elbow or behind the ear.
• Leave in place for 24-48 hours without washing off.
• Monitor for increased redness, itching, burning, or any new rash.
• If no reaction occurs after 48 hours, proceed with wider application.
• If any reaction develops, discontinue use and note which ingredients in the formula you may be sensitive to.

Step 3: Apply a thin, even layer

Squeeze a pea-sized amount onto a clean fingertip. A pea-sized amount covers roughly a palm-sized area of skin. Gently pat or spread a thin, even layer over the affected area. Do not rub vigorously - particularly over actively inflamed or broken skin. Do not apply thick layers; a thin, consistent application allows Borneolum to drive the active compounds through the stratum corneum more effectively than excess cream sitting on the surface.

Allow the cream to fully absorb before covering with clothing. If applying to the scalp, work a small amount directly onto visible plaques before washing.

Step 4: Frequency

• During active flare-ups: apply 2-3 times daily - morning, evening, and once more during the day if symptoms are intense.
• For maintenance: once daily or twice daily once symptoms begin improving. Because QICAOGANGMU is steroid-free, there is no duration ceiling - it can be used continuously for long-term maintenance without risk of skin thinning or rebound.
• Consistency matters more than quantity: twice-daily use every day produces significantly better outcomes than occasional heavy application. Ku Shen's NF-kB modulation is cumulative and requires sustained application to build.

Step 5: Hand hygiene

Wash hands thoroughly before application to avoid introducing bacteria to sensitive or broken skin, and after application to avoid inadvertently touching eyes or mucous membranes.

Step 6: Layering with other products

If using emollients, barrier creams, or prescription topical medications:

• Apply QICAOGANGMU first directly to the affected skin.
• Allow 5 minutes for absorption.
• Apply your emollient or other products on top to seal in moisture and the herbal actives.
• If using prescription topical steroids: apply QICAOGANGMU on non-steroid days during a taper, or on adjacent unaffected areas while using steroid on the active plaque. Inform your dermatologist of all topical products you are using.

Safety considerations

For external use only

Avoid contact with eyes, mouth, and mucous membranes. If accidental contact occurs, rinse thoroughly with clean water.

Potential sensitivities

Although natural, some individuals may have sensitivities to specific botanical ingredients - particularly Menthol in people with cold receptor hypersensitivity, or any of the herbal actives in people with plant allergies. The 24-48 hour patch test identifies these before widespread use. If you have known allergies to any listed ingredients, do not use.

Product quality and adulteration

Some products sold as "herbal" or "natural" for eczema have been found to contain undisclosed corticosteroids - which produce rapid results by suppressing inflammation, but carry all the risks of steroids while being labelled as natural. PMID 10037629, PMID 8845209. QICAOGANGMU is independently batch-tested steroid-free - results at our purity report. Always buy from verified sellers - see our authenticity guide.

Topical steroid withdrawal (TSW)

If you are currently using topical corticosteroids, do not stop abruptly. Abrupt cessation after prolonged use can trigger severe rebound inflammation. PMID 16384751. QICAOGANGMU can be used alongside steroids during a gradual taper and continued after stopping - there is no rebound from stopping QICAOGANGMU itself. Consult a dermatologist for a supervised tapering plan if you are on high-potency steroids (clobetasol, betamethasone).

Underlying conditions and infections

QICAOGANGMU provides symptomatic relief and supports skin healing. It is not a substitute for medical diagnosis or treatment of severe underlying conditions. Seek prompt medical advice if your skin condition is severe, rapidly worsening, accompanied by fever, or shows signs of secondary bacterial infection (oozing, crusting, warmth, spreading redness). Do not apply to actively infected open wounds without medical guidance.

Children under 12 months

Consult a paediatrician before use in infants under 12 months. For children over 12 months, mandatory patch test required. See our infant safety guide for full guidance.

Pregnancy and breastfeeding

Topical application of the formula ingredients at stated concentrations results in minimal systemic absorption. However, as with any topical product during pregnancy or breastfeeding, consult your healthcare provider before use.

Storage

Store in a cool, dry place away from direct sunlight and excessive heat. Keep out of reach of children. Do not use after the expiry date printed on the tube.

Integrating QICAOGANGMU into your skincare routine

QICAOGANGMU works best as part of a consistent routine that addresses both the symptomatic and environmental drivers of eczema and psoriasis:

• Consistent emollient use: apply QICAOGANGMU first, then your regular moisturiser immediately after to seal in the herbal actives alongside skin moisture. The combination of active treatment and barrier support is consistently more effective than either alone.
• Identify and avoid triggers: for eczema - fragrances, harsh soaps, synthetic fabrics, certain metals in jewellery. For psoriasis - stress, streptococcal infections, certain medications (beta-blockers, lithium), alcohol, smoking. PMID 26025581
• Break the itch-scratch cycle: QICAOGANGMU's Menthol and Borneolum provide immediate itch cooling within minutes. Supplement with short-cut fingernails, cool compresses, and cotton gloves at night to prevent night scratching.
• Diet: reduce alcohol (strong evidence for worsening psoriasis and eczema), refined sugar, and processed foods. Increase omega-3 fatty acids.
• Stress management: stress is a major documented trigger for both eczema and psoriasis. Mindfulness, regular exercise, and adequate sleep reduce HPA axis activation that worsens inflammatory skin conditions.

Frequently asked questions

How quickly does QICAOGANGMU work?

Menthol's TRPM8 activation provides cooling itch relief within minutes of first application - you will feel this immediately. Borneolum's penetration enhancement means the anti-inflammatory actives begin working faster than they would in a non-enhanced formula. Visible reduction in redness and itch typically develops over 5-14 days of consistent twice-daily use. Full improvement in plaque thickness or chronic eczema generally takes 3-6 weeks.

Can I use QICAOGANGMU on my face?

Yes - QICAOGANGMU is steroid-free, which means it does not carry the skin-thinning risk that makes topical steroids unsuitable for daily long-term use on the face. Apply a thin layer to clean, slightly damp facial skin. Avoid contact with eyes. Patch test on the inner forearm before first facial use.

Can I use QICAOGANGMU on children?

For children over 12 months: yes, with mandatory 24-48 hour patch test first. For infants under 12 months: consult a paediatrician before use. The steroid-free formula carries no HPA axis suppression risk, which makes topical steroids particularly concerning in young children. See our infant guide for full details.

Can I use QICAOGANGMU while using steroid cream?

Yes - this is the recommended steroid-sparing approach. Use your prescribed steroid for acute flare control and apply QICAOGANGMU on non-steroid days and for daily maintenance. Progressively extend the gaps between steroid applications as QICAOGANGMU establishes. There is no interaction between the two - just inform your dermatologist of all topical products in use.

Is there a risk of developing dependency on QICAOGANGMU?

No. QICAOGANGMU contains no steroids and creates no receptor dependency. Stopping QICAOGANGMU simply means the anti-inflammatory protection fades - it does not cause the rebound inflammation (TSW) associated with stopping topical corticosteroids. You can stop or pause use at any time without risk of withdrawal.
