Psoriasis Causes, Symptoms and Natural Treatment - Chinese Herbal Guide (2026)

By Ava Huang, Herbal Science Researcher at QICAOGANGMU | Updated: May 2026 | Reading time: 15 minutes

Psoriasis affects around 2-3% of the global population - roughly 125 million people worldwide. If you have it, you already know the statistics are cold comfort. What you want to know is why it keeps coming back, and what you can actually do about it beyond relying on creams that stop working.

Quick answer: Psoriasis is a chronic autoimmune condition where T-cells attack skin cells, accelerating keratinocyte turnover from 28 days to 3-5 days and producing the characteristic thick silvery scales. In TCM it is Blood Heat (active, expanding plaques) or Blood Stasis (chronic, dark plaques). Sophora flavescens has shown psoriasiform inflammation reduction comparable to topical steroids in vitro. PMID 38358770. Oxymatrine improved PASI scores in clinical studies. PMID 28450041. QICAOGANGMU addresses psoriasis through NF-kB inhibition and Borneolum-enhanced penetration through the thick scale barrier.

What is psoriasis?

Psoriasis is a chronic autoimmune skin condition characterised by the rapid overproduction of skin cells. In normal skin, cells regenerate over about 28-30 days. In psoriasis, this cycle accelerates to 3-5 days. The result is a build-up of skin cells that forms the raised, scaly plaques that define the condition.

Psoriasis is not contagious and is not caused by poor hygiene. It is driven by an immune system malfunction - specifically, T-cells mistakenly attacking healthy skin cells and triggering an inflammatory cascade that speeds up skin cell production.

Types of psoriasis

Plaque psoriasis is the most common form, affecting around 80-90% of people with psoriasis. It appears as raised, red or pink patches covered with silvery-white scales. It typically affects the elbows, knees, scalp, and lower back - though it can appear anywhere on the body.

Guttate psoriasis appears as small, drop-shaped lesions scattered across the trunk and limbs. It often develops after a streptococcal throat infection and is more common in children and young adults. It may resolve on its own or progress to plaque psoriasis.

Inverse psoriasis affects skin folds - the groin, armpits, under the breasts, and around the genitals. Because it affects moist areas rather than dry skin, it tends to appear as smooth, red patches without the typical scaling. It is particularly uncomfortable due to friction and moisture in affected areas.

Pustular psoriasis presents as white pustules (blisters of non-infectious pus) surrounded by red skin. It can be localised to the hands and feet or generalised across the body. Generalised pustular psoriasis can be serious and requires medical attention.

Erythrodermic psoriasis is a rare but severe form that affects most of the body surface. The skin becomes red, inflamed, and sheds in sheets. It can be life-threatening and requires urgent medical care.

Scalp psoriasis is extremely common - around 50% of people with plaque psoriasis experience it on the scalp. It can range from mild scaling to thick, crusted plaques that extend beyond the hairline.

Nail psoriasis affects the fingernails and toenails, causing pitting, discolouration, thickening, and separation of the nail from the nail bed.

What causes psoriasis - and what triggers flares?

Psoriasis has a clear genetic component - if one parent has psoriasis, there is roughly a 10% chance their child will develop it. If both parents have it, the risk rises to around 50%. However, having the genetic predisposition does not mean psoriasis will develop - it typically requires a trigger.

Common psoriasis triggers

Stress - one of the most consistently reported triggers. Psychological stress activates inflammatory pathways that can initiate or worsen psoriasis flares.
Infections - particularly streptococcal throat infections, which can trigger guttate psoriasis. HIV and certain fungal conditions can also worsen psoriasis.
Medications - lithium, beta-blockers, antimalarials, and NSAIDs in some individuals. If a new medication coincides with a flare, always discuss with your doctor.
Skin injury (Koebner phenomenon) - psoriasis can develop at sites of skin injury including cuts, sunburn, insect bites, or any trauma to the skin.
Alcohol - heavy alcohol consumption is associated with more severe psoriasis and reduced response to treatment. One of the few dietary factors with consistent evidence.
Smoking - both a risk factor for developing psoriasis and a factor that makes existing psoriasis harder to treat.
Cold, dry weather - many people find psoriasis worsens in winter when humidity is low.
Hormonal changes - psoriasis can improve during pregnancy and flare postpartum. Puberty and menopause can also affect psoriasis activity.

How Traditional Chinese Medicine understands and classifies psoriasis

In Traditional Chinese Medicine, psoriasis is not treated as a single condition with one treatment. It is differentiated into patterns based on the specific appearance and behaviour of the plaques, the patient's overall constitution, and accompanying symptoms. The same diagnosis in Western medicine can correspond to several different TCM patterns, each requiring a different treatment approach.

Blood Heat psoriasis - the most common active pattern

This pattern corresponds to active, flaring psoriasis. The plaques are bright red or deep pink, actively expanding at the edges, and new lesions are appearing. The scales are silvery and shed easily. There may be significant itching and a sensation of heat in the skin. This pattern is more common in younger patients and during stress-induced flares.

In TCM terms, excessive Heat in the Blood drives the rapid skin cell proliferation seen in active psoriasis. Treatment focuses on cooling the Blood and clearing Heat - using herbs like Sheng Di Huang (Rehmannia), Mu Dan Pi (Moutan Bark), Chi Shao (Red Peony Root), and Bai Mao Gen (Woolly Grass Rhizome).

Blood Stasis psoriasis - the chronic stubborn pattern

This pattern corresponds to long-standing, stable psoriasis where plaques have been present for months or years without significant change. The plaques are dark red or purple-red, thick, and often feel hard to the touch. Scaling may be less pronounced. The plaques respond slowly to treatment.

Blood Stasis indicates impaired circulation and an entrenched inflammatory process. Treatment focuses on activating Blood circulation - using herbs like Dan Shen (Salvia), Hong Hua (Safflower), and Tao Ren (Peach Kernel).

Blood Deficiency and Wind-Dry psoriasis - the dry, chronic pattern

This pattern is most common in elderly patients, in people with long-term psoriasis, or following illness. The plaques are pale pink or light red rather than bright red, covered with fine, dry scales. Itching tends to be mild. The plaques are stable rather than actively expanding.

Treatment focuses on nourishing the Blood and moisturising the skin - using herbs like Dang Gui (Angelica Root), Shu Di Huang (Prepared Rehmannia), and He Shou Wu (Polygonum).

Why TCM pattern matters for treatment

Blood Heat patterns benefit most from cooling, anti-inflammatory herbs. Blood Stasis patterns need herbs that improve circulation. Blood Deficiency patterns need nourishing, moisturising approaches. The herbs in QICAOGANGMU - particularly Sophora flavescens (Ku Shen) for inflammation and itch, She Chuang Zi for antimicrobial and itch action, and Borneolum for penetration through the thick psoriasis scale barrier - address the inflammatory and itch components common across all three patterns, which is why the cream is effective across the range of psoriasis presentations. For a deeper explanation, see our TCM for eczema and psoriasis guide.

The limitations of conventional psoriasis treatments

Topical treatments

Topical corticosteroids are the most commonly prescribed first-line treatment. They reduce inflammation and slow skin cell production rapidly. However, long-term use causes skin thinning, telangiectasia, and rebound flares when stopped. Potent steroids like clobetasol are effective but not suitable for extended daily use, particularly on the face, genitals, or skin folds.

Vitamin D analogues (calcipotriol, calcitriol) slow skin cell production and reduce scaling. They are often used in combination with topical steroids and have a better long-term safety profile - but can irritate the skin, particularly on the face.

Coal tar is one of the oldest established treatments for psoriasis. It slows rapid skin cell turnover and reduces inflammation. Available in shampoos, creams, and bath solutions. Downsides include smell, staining, and photosensitivity.

Systemic treatments

For moderate to severe psoriasis, systemic drugs including methotrexate, ciclosporin, and acitretin may be prescribed. Biologic therapies (including adalimumab, ustekinumab, secukinumab, and ixekizumab) are highly effective for severe psoriasis but are expensive, require injections, and carry immunosuppression risks.

The treatment gap - why people look to natural options

Most conventional topical treatments manage flares but do not address the underlying immune dysregulation. Patients often find themselves in a cycle of treatment and relapse. This is why many people with psoriasis look to Chinese medicine, dietary approaches, and herbal creams as part of a long-term management strategy - to reduce reliance on steroids and extend periods of remission.

The best Chinese herbal cream for psoriasis - what to look for

Active anti-inflammatory herbs with documented evidence

The most important ingredient in any Chinese herbal cream for psoriasis is an anti-inflammatory herb with clinical evidence. Sophora flavescens (Ku Shen) is the strongest candidate - its active compounds matrine and oxymatrine have been shown to inhibit the inflammatory cytokines involved in psoriasis, including TNF-alpha and IL-17. PMID 38358770. Oxymatrine improved PASI scores in clinical studies of psoriasis patients. PMID 28450041. Matrine also reduced TNF-alpha and IL-4 via STAT3/AKT1 pathways. PMID 36216196

Antipruritic action

Itch is a defining and often debilitating symptom of psoriasis. A cream without meaningful itch relief will not be tolerated regardless of its anti-inflammatory properties. Menthol (immediate cooling relief via TRPM8 receptor activation) and She Chuang Zi - Cnidium monnieri, with documented TRPV3 itch receptor inhibition - are the two most clinically validated options. PMID 30108138, PMID 30067875

No hidden steroids

Some products sold as herbal or natural have been found to contain undisclosed corticosteroids. PMID 10037629. This is particularly a risk with products from unregulated markets. Always choose a product with full ingredient transparency from a regulated supplier. QICAOGANGMU publishes its full ingredient list and has been independently verified as steroid-free at our purity report.

Penetration enhancement

The thick scale of plaque psoriasis creates a physical barrier to topical treatment. Borneolum Syntheticum (Bing Pian) temporarily disrupts stratum corneum lipid structure to drive active compounds deeper into the skin - including through the thickened scale of psoriasis plaques. PMC5452010. This is one reason why multi-ingredient TCM formulas often outperform single-herb preparations in practice for psoriasis.

Staph aureus protection

Staphylococcus aureus colonisation is a significant driver of skin inflammation in psoriasis as well as eczema. Stemonae Radix (Bai Bu) provides documented antibacterial activity against Staph aureus via COX-2 and NO suppression. PMID 35295975. This fifth ingredient in QICAOGANGMU addresses a pathway that single-herb psoriasis creams typically do not cover.

Diet for psoriasis - what TCM and modern research agree on

Diet does not cause psoriasis, but it can significantly influence flare frequency and severity. Both TCM psoriasis diet principles and modern nutritional research point to similar conclusions.

Foods associated with worsening psoriasis

Alcohol - the strongest dietary link to psoriasis severity. Multiple studies confirm heavy alcohol consumption worsens psoriasis and reduces treatment effectiveness. In TCM, alcohol generates Heat and Dampness - directly fuelling the Blood Heat pattern most common in active psoriasis.
Red meat and saturated fat - associated with increased systemic inflammation. In TCM, rich and greasy foods generate Heat in the Blood.
Refined sugar and processed carbohydrates - drive systemic inflammation through blood glucose spikes and promote the gut dysbiosis associated with psoriasis.
Nightshades (tomatoes, peppers, aubergine, potatoes) - some people with psoriasis report sensitivity to nightshades. The evidence is anecdotal but consistent enough to be worth testing with a 4-week elimination.
Gluten - psoriasis has a higher-than-expected association with coeliac disease and non-coeliac gluten sensitivity. A gluten-free diet significantly improves psoriasis in those with confirmed gluten sensitivity.

Foods that support psoriasis management

Oily fish (salmon, mackerel, sardines) - omega-3 fatty acids reduce the production of inflammatory prostaglandins and cytokines. Several clinical trials have shown modest but consistent improvements in psoriasis severity with omega-3 supplementation.
Colourful vegetables and fruits - rich in antioxidants that reduce systemic oxidative stress. In TCM, foods that cool the Blood include bitter melon, water chestnut, and dark leafy greens.
Turmeric - curcumin has documented anti-inflammatory and anti-psoriatic activity. Small clinical trials have shown reductions in PASI scores with curcumin supplementation.
Probiotics and fermented foods - gut microbiome dysbiosis is increasingly associated with psoriasis. Kefir, kimchi, and yogurt support beneficial gut bacteria and may reduce systemic inflammation.
TCM food remedies - mung bean soup and lotus root are classical Blood Heat-clearing foods in TCM psoriasis diet protocols. Job's tears (Yi Yi Ren / pearl barley) is used to drain Dampness and reduce inflammation.

How to use QICAOGANGMU for psoriasis alongside conventional treatment

The most effective approach for most people is combining conventional and herbal treatments strategically, rather than choosing one or the other.

For active flares: use your prescribed topical steroid or vitamin D analogue to bring the flare under control quickly. Continue applying QICAOGANGMU on adjacent unaffected areas during this time to maintain protection and reduce the area affected.
For daily maintenance: apply QICAOGANGMU twice daily to affected plaques. This addresses the ongoing inflammation and itch without the skin-thinning risk of daily steroid use. The goal over time is to use steroids only for acute flares, while herbal treatment handles daily management.
For reducing steroid frequency: as plaques stabilise with consistent herbal cream use, gradually extend the gap between steroid applications - from daily, to every other day, to every third day. Replace the steroid days with herbal cream only.
For diet and lifestyle: reducing alcohol, managing stress, and following the dietary guidelines above work on the systemic drivers of psoriasis that no topical treatment can address on its own.

How to apply

Wash with plain warm water only - no soap or cleanser on the affected area. Pat gently dry, leaving slightly damp.
Patch test first - apply a small amount to the inner forearm for 24 hours before first widespread use.
Apply a thin layer - a pea-sized amount covers a palm-sized area. Gently pat until absorbed. The Borneolum will drive all actives through the scale layer.
Apply 2-3 times daily during active flares. Reduce to once daily for maintenance. No duration restriction.

Frequently asked questions

What is the best Chinese cream for psoriasis?

Look for a Chinese herbal cream containing Sophora flavescens (Ku Shen) as its primary active ingredient - this has the strongest evidence base for psoriasis, with documented NF-kB inhibition and published PASI score improvement in clinical studies. QICAOGANGMU combines Ku Shen with Cnidium monnieri (She Chuang Zi), Borneolum (penetration through psoriasis scale), Stemonae Radix (Staph protection), and Menthol in a steroid-free, prescription-free formulation. See the full ingredient review and safety analysis for complete details.

Can Chinese medicine cure psoriasis permanently?

No treatment currently cures psoriasis permanently - including biologics. TCM does not claim otherwise. The realistic goal of Chinese medicine for psoriasis is to reduce the frequency and severity of flares, extend periods of remission, and reduce dependence on corticosteroids. Many patients achieve extended clear periods - sometimes years - with consistent TCM management and lifestyle changes.

How long does Chinese herbal cream take to work for psoriasis?

Most people notice a reduction in itch and redness within 7-14 days of consistent twice-daily application. Visible reduction in plaque thickness and scaling typically takes 3-6 weeks. The Blood Stasis pattern (dark, thick, chronic plaques) responds most slowly and may take 8-12 weeks to show significant change. Borneolum significantly speeds up penetration through thick scale, which is why the formula is more effective for plaque psoriasis than single-ingredient herbal products.

Is QICAOGANGMU safe for psoriasis on the face and genitals?

Yes - QICAOGANGMU is steroid-free, which means it does not carry the skin-thinning risk that makes topical steroids unsuitable for long-term use on the face, genitals, or skin folds. It is suitable for use on all body areas including inverse psoriasis in skin folds and facial psoriasis. Always do a patch test on a small area first.

What foods should I avoid with psoriasis?

The most consistently supported changes are reducing alcohol (strong evidence), cutting refined sugar and processed carbohydrates, and increasing omega-3 fats. If you suspect gluten sensitivity, a trial elimination is worthwhile. In TCM terms, avoid foods that generate Blood Heat - spicy foods, alcohol, and red meat in excess - and eat more cooling foods like mung beans, bitter melon, and dark leafy greens. Our TCM skin treatment guide covers the diet section in more detail.

Can psoriasis be mistaken for eczema?

Yes - and this is common. Both conditions cause red, itchy, scaly skin, but they have distinct features. Psoriasis plaques tend to be thicker, more clearly defined, and covered with silvery scales. Eczema tends to be more fluid - weeping, crusting, or appearing in skin creases. If you are unsure which condition you have, see a dermatologist for a diagnosis. QICAOGANGMU is used for both conditions, which is relevant - its five-herb formula addresses inflammatory and itch mechanisms common to both.

Does QICAOGANGMU work for scalp psoriasis?

QICAOGANGMU can be applied to the scalp, though cream formulations are less convenient for scalp use than shampoos or lotions due to the hair. Many people apply it directly to visible scalp plaques before washing. The antifungal action of She Chuang Zi is particularly relevant for scalp psoriasis, which often has a secondary Malassezia (fungal) component that worsens scaling.
