Essential Oils for Psoriasis: What May Help, What to Be Cautious About & How to Use Them Safely
Essential oils attract significant interest in psoriasis communities — many people try them as a gentler, natural complement to medical treatment. Some find genuine comfort; others develop contact reactions. Understanding which oils have the most plausible benefit, which carry the most risk, and how to use them appropriately makes the difference between a useful complementary measure and a contact allergy that worsens the skin they're intended to soothe.
Can essential oils help psoriasis?
Essential oils may help soothe symptoms like dryness and irritation for some people — but they can also trigger sensitivity or flare-ups, especially on psoriasis-prone skin, and the gap between those two outcomes is determined by factors that most essential oil content for psoriasis entirely fails to address. The wellness community's enthusiasm for essential oils and the medical community's general dismissal of them both miss the more nuanced and more useful picture: some essential oils contain specific compounds — terpinen-4-ol in tea tree, boswellic acids in frankincense, bisabolol in chamomile — with documented anti-inflammatory and antimicrobial activity at pathways relevant to psoriasis, while others contain known contact allergens and chemical irritants that on psoriasis-prone skin's elevated permeability and sensitisation risk are more likely to worsen than improve the condition. There's a further consideration specific to psoriasis that almost no essential oil article addresses: the Koebner phenomenon means that the friction of application, the chemical irritation from undiluted oils, or a contact allergen reaction from a sensitising compound can all trigger new plaque formation at the application site — making the difference between a correctly chosen, correctly diluted oil and the wrong product applied incorrectly not just a question of efficacy but of whether the intervention actively worsens the condition it's intended to help.
What essential oils can and cannot do for psoriasis
This framing matters before anything else. Essential oils are concentrated plant extracts with anti-inflammatory, antimicrobial, and aromatic properties. Several have documented bioactive compounds — chamomile's bisabolol, frankincense's boswellic acid fractions, geranium's citronellol — that have anti-inflammatory properties in laboratory research.
What they cannot do is address psoriasis at the pathological level. Psoriasis is driven by T-cell-mediated immune dysregulation and Th17/IL-17 inflammatory cascades. No essential oil compound penetrates to this depth or operates on these pathways at concentrations achievable through topical application. The benefit of essential oils for psoriasis is symptomatic comfort — reduced itch, mild local anti-inflammatory soothing, and the stress reduction from aromatherapy — rather than disease modification.
That is still genuinely useful. Itch reduction and stress management both matter for psoriasis management — and aromatherapy specifically (inhalation rather than topical application) addresses the stress-HPA axis pathway covered in the stress article in this series without the contact allergen risk of topical use.
Oils with more specific anti-inflammatory rationale
Chamomile (Roman chamomile, Chamaemelum nobile) contains bisabolol and alpha-bisabolol oxide, which have documented anti-inflammatory and anti-irritant properties in dermatological research. Of the commonly used essential oils for psoriasis, chamomile has one of the more coherent mechanistic rationales and is generally considered lower-risk for sensitive skin than many alternatives. Still requires dilution and patch testing.
Frankincense (Boswellia serrata or Boswellia carterii) contains boswellic acid fractions with documented 5-lipoxygenase inhibition — reducing leukotriene production in the same inflammatory pathway that fish oil omega-3s target. The evidence is primarily from oral Boswellia extracts rather than topical essential oil, but the anti-inflammatory rationale is specific and the oil is generally well-tolerated. Dilute to 1–2% in a carrier oil.
Geranium contains citronellol, geraniol, and linalool — the latter of which is also a lavender component and a potential allergen. Rose geranium oil is often described as having mild astringent and anti-inflammatory properties. Lower-risk than lavender or tea tree for most people, but linalool content means the same patch-testing caution applies.

Eucalyptus provides a cooling sensation from its high cineole (1,8-cineole) content, which has mild analgesic properties relevant to the itch and discomfort of psoriasis. The cooling effect on inflamed plaques can provide temporary comfort. However, eucalyptus is also a skin irritant at higher concentrations and should be diluted more aggressively than gentler oils — 0.5–1% maximum on psoriasis-affected skin.
Nikura Eucalyptus Essential Oil— a pure eucalyptus oil. Use at 0.5–1% dilution only. Not suitable on or near active plaques; more appropriate for intact skin around affected areas. (Affiliate link.)
The contact allergen issue: what to know before applying anything
Psoriasis skin, like eczema skin, has a compromised barrier that allows topical compounds to penetrate more readily — which means contact sensitisation to essential oil compounds is more likely than on intact skin.
Two of the oils most commonly recommended for psoriasis are also two of the most documented contact allergens in dermatology:
Lavender oil contains linalool and linalyl acetate — compounds that oxidise on exposure to air and become increasingly allergenic. As covered in the lavender and eczema article in this series, lavender is one of the most common patch-test-confirmed contact allergens in the UK. The contact allergy risk is the same for psoriasis skin as for eczema skin — perhaps higher given the compromised barrier.
Tea tree oil — covered in the tea tree oil and eczema article — is among the most frequently identified contact allergens from skincare products. Its active compounds also oxidise with age and improper storage, becoming more allergenic. For psoriasis skin where the Koebner phenomenon means any skin irritation can trigger new plaques, a contact reaction from tea tree oil is a more significant risk than for intact skin.
This doesn't mean lavender and tea tree can never be used for psoriasis — but they should be used with specific precautions: fresh, properly stored oil; significant dilution (1% or lower); patch testing; and avoidance on or near active plaques.
How to use essential oils safely
If you choose to try them:
Dilute properly: Mix 1–2 drops with 1 teaspoon of carrier oil such as jojoba, coconut, or sweet almond.
Patch‑test first: Apply to a small, unaffected area for 24 hours to check for irritation.
Avoid open or broken skin: Oils can sting or worsen inflammation.
Use occasionally: Treat essential oils as short‑term support, not daily treatments.
Never apply undiluted oil directly on psoriasis plaques — it can aggravate redness and dryness.
Less is more with sensitive skin.
Oils and Blends to Avoid with Psoriasis
Some essential oils can increase irritation or trigger allergic reactions, including:
lemongrass
clove
cinnamon
peppermint
citrus oils (lemon, orange, bergamot)
Many “natural” blends contain hidden fragrance compounds, so always check labels.
The lavender recommendation: using it safely
Given the documented contact allergy risk, lavender essential oil on psoriasis plaques directly is not recommended as a routine practice. The appropriate use for lavender in psoriasis management is aromatherapy — inhalation via diffuser or pillow, which captures the stress-reduction benefit of lavender (through HPA axis modulation) without skin contact.
Recommended Products
Tisserand Aromatherapy Lavender Organic Essential Oil
for use in a diffuser or on a pillow, not for topical application on psoriasis-affected skin
Australian Bodycare Tea Tree Oil Scalp Serum
for scalp psoriasis with seborrhoeic involvement. Use as directed, leave as indicated, and discontinue if irritation develops
Nikura Roman Chamomile Essential Oil
a pure Roman chamomile oil suitable for dilution in a carrier. Roman chamomile (Chamaemelum nobile) is the more appropriate species for skin use than German chamomile.
How to use essential oils safely on psoriasis skin
Always dilute. 1% dilution (1 drop per 5ml carrier oil) is appropriate for psoriasis-adjacent skin. On clear skin around plaques, 1–2%. Never apply undiluted essential oil directly to psoriasis plaques.
Choose appropriate carrier oils. Jojoba and sweet almond are the most appropriate — they have balanced fatty acid profiles and lower oleic acid content than olive oil (the oleic acid barrier-disruption risk discussed in the olive oil article applies here too).
Patch test 24 hours before use. On clear skin on the inside of the elbow, not on plaque tissue.
Apply without friction. The Koebner phenomenon means rubbing oil into plaque skin can trigger new plaques at the friction site. Pat or press gently rather than massaging.
Store oils correctly and discard old bottles. Oxidised essential oils are more allergenic than fresh ones. Keep tightly closed, in a cool dark place, and discard open bottles after 12 months.
Avoid on broken or actively inflamed plaques. Essential oils on compromised skin surfaces cause stinging and increase allergen penetration.
Skin support for psoriasis-prone skin
Essential oils work at the surface level — soothing comfort and mild topical anti-inflammatory effects. The systemic immune dysfunction, nutritional deficiencies, and chronic inflammatory burden of psoriasis require internal support that no topical intervention can address.
Drought's Skin Support Formulaprovides 14 nutrients including vitamin D, zinc, vitamin C, and magnesium — addressing the internal dimensions of psoriasis management that essential oils cannot reach. Made in the UK, suitable for vegetarians, designed for consistent long-term daily use.
FAQs: Essential oils and psoriasis
Are essential oils safe for psoriasis?
With dilution, patch testing, fresh product, and avoidance of active plaques — several are reasonably well-tolerated. Lavender and tea tree carry the most contact allergy risk and should be used cautiously.
Which essential oil is best for psoriasis?
Chamomile (Roman) and frankincense have the most specific anti-inflammatory rationale and lower sensitisation risk. Lavender is better used via aromatherapy than topically.
Can essential oils cure psoriasis?
No — psoriasis is a chronic inflammatory condition. Oils may soothe symptoms but cannot treat the root cause.
Can essential oils make psoriasis worse?
Yes — through contact sensitisation and the Koebner phenomenon from friction during application. Any new plaques appearing in the pattern of oil application should prompt stopping use.
How should I dilute essential oils for psoriasis?
1% dilution (1 drop per 5ml carrier oil) for psoriasis-prone skin; 0.5% for more sensitive presentations. Never apply undiluted.
Is lavender good for psoriasis?
As an aromatherapy tool for stress reduction, yes. As a topical oil on psoriasis plaques, its contact allergy risk (linalool sensitisation) makes it inappropriate for regular use on affected skin.
Can I use essential oils on scalp psoriasis?
Pre-formulated scalp products containing tea tree at controlled concentrations are more appropriate than home dilution for the scalp. For pure plaque psoriasis on the scalp without seborrhoeic elements, coal tar shampoo has considerably stronger evidence.
Should I use essential oils daily?
Only if your skin tolerates them well.
Is it safe to add oils to bath water?
Only when mixed first with a carrier oil or emulsifier to prevent floating undiluted oil touching the skin.
Summary
Essential oils offer mild symptomatic comfort for psoriasis — primarily through local anti-inflammatory compounds (chamomile's bisabolol, frankincense's boswellic fractions) and the stress-reduction pathway of aromatherapy. They do not address psoriasis at the immunological level. Lavender and tea tree are the most commonly recommended but also the most documented contact allergens — lavender is better used via aromatherapy than topically on psoriasis skin; tea tree in scalp psoriasis with seborrhoeic elements is more appropriate as a pre-formulated scalp product than as a diluted pure oil. All essential oils require dilution, patch testing, gentle application (Koebner risk), and fresh product with proper storage. They are a comfort measure alongside, not a replacement for, appropriate skincare and medical management.
In short:
May provide temporary relief
Can irritate sensitive skin
Must be diluted properly
Not a treatment for psoriasis
Essential oils can offer temporary soothing benefits, but they’re not a long-term solution for psoriasis. If you’re looking for more consistent results, it’s important to focus on what’s driving your skin beneath the surface.
Supporting your skin from within can help reduce flare-ups and improve long-term stability.
