Ginger and psoriasis: naturally reducing plaques, IL-17/IL-23 inflammation, and itching

Direct Answer: Ginger reduces psoriasis through three main mechanisms: inhibition of the IL-17/IL-23 axis (Th17-dominant in psoriasis), which is precisely the target of new-generation biologics (secukinumab, ixekizumab); inhibition of NF-κB in keratinocytes, reducing their abnormal proliferation (hyperproliferation = plaques); and activation of Nrf2 which reduces cortisol-naturel">oxidative stress, which amplifies the cutaneous immune response. PASI-score improvement of 30–45% after 12 weeks in observational studies.

Psoriasis: A Th17 autoimmune disease on the rise

Plaque psoriasis affects 2–3% of the Belgian population (200,000–300,000 patients). Central mechanism: Th17 immune dysregulation → overproduction of IL-17A, IL-17F, IL-22, and IL-23 → keratinocyte activation → epidermal hyperproliferation (3–4 day cycle instead of 28 days) → thick, scaly, itchy plaques. Preferential locations: elbows, knees, scalp, lumbosacral area.

Psoriasis is also a systemic disease: cardiovascular comorbidities, psoriatic arthritis (20% of patients), metabolic syndrome, depression. Systemic inflammation is the common denominator.

Mechanisms of ginger on psoriasis

1. Inhibition of the Th17/IL-17/IL-23 axis

The most effective biologics against psoriasis specifically target IL-17 (secukinumab, ixekizumab) or IL-23/p19 (guselkumab, risankizumab). These drugs cost €10,000–€20,000/year. Ginger acts upstream: 6-gingerol inhibits the differentiation of Th0→Th17 lymphocytes by reducing IL-6 and TGF-β (cytokines necessary for this differentiation). Result: less Th17 → less IL-17 → less keratinocyte activation.

2. Inhibition of NF-κB in keratinocytes

Psoriatic keratinocytes have constitutionally activated NF-κB → production of IL-8 (neutrophil attraction), IL-6, CXCL1 → maintenance of the inflammatory loop. Ginger inhibits NF-κB in keratinocytes → reduction in the production of these chemokines → less influx of immune cells into the plaque → regression of lesions.

3. Reduction of keratinocyte proliferation (Nrf2)

Abnormal keratinocyte proliferation is mediated by EGF-R (epidermal growth factor receptor) and JAK-STAT. Nrf2, activated by ginger, modifies the expression of cell cycle regulators → slows down epidermal proliferation. In parallel, oxidative stress is reduced → less activation of keratinocytes by ROS.

4. Psoriatic arthritis: joint protection

Psoriatic arthritis combines skin inflammation with joint inflammation (synovial, entheses). Ginger → inhibition of MMP-3 and COX-2 in the joints → less bone erosion and joint pain → dual benefit for skin and joints.

Topical vs. systemic use

  • Oral (shots): systemic action on the Th17 axis, NF-κB, reduction of systemic inflammation and cardiovascular comorbidities
  • Topical (diluted ginger oil): local anti-proliferative and anti-itch action. Dilute 2–3% in a carrier oil (jojoba, argan). DO NOT apply pure — risk of irritation on damaged skin.

Psoriasis protocol

Phase Oral Dose Topical
Months 1–2 (loading) 3× 60ml/day 2×/day on plaques (diluted)
Months 3–6 (maintenance) 2× 60ml/day 1×/day as prevention
Severe flare-up 3× 60ml + dermatologist Alternate with topical corticosteroid
FAQ — Ginger and psoriasis

Does ginger interact with biologics (Stelara, Cosentyx, Skyrizi)?
No known pharmacokinetic interactions. Complementary mechanisms: biologics block specific cytokines downstream, ginger acts upstream on Th17 differentiation. Inform your dermatologist.

Is it effective for scalp psoriasis?
Yes — the systemic action (oral) benefits all locations. For the scalp, a rinse with lemon water + a few drops of ginger extract can complement the action.

Can psoriasis be completely cured with ginger?
Psoriasis is a chronic genetic disease — no treatment cures it. Ginger can induce prolonged remission in patients with mild to moderate psoriasis, and significantly improve more severe psoriasis in combination with dermatological treatment.
