Ginger and atopic dermatitis: soothing eczema through anti-inflammation

The ginger reduces theanti-inflammatory-inflammation-natural-remedy">cutaneous inflammation of atopic dermatitis by inhibiting IL-4, IL-13 and TSLP pathways — the central Th2 cytokines in atopic eczema. A 2022 study (Journal of Investigative Dermatology) on AD mouse models shows a 42% reduction in skin severity score with a combined topical and oral ginger extract.

Atopic dermatitis vs contact eczema: distinction

Atopic dermatitis (AD) is a chronic inflammatory disease of the skin mediated by an aberrant Th2 immune response. It differs from contact eczema (local allergic reaction). For AD, the key cytokines are IL-4, IL-13, IL-31 (pruritus), and TSLP (maintaining inflammation).

Anti-AD mechanisms of ginger

• Anti-Th2: 6-shogaol inhibits T cell differentiation into Th2 → ↓ IL-4, IL-13
• Anti-pruritus: zingerone reduces the production of substance P (mediator of pruritus)
• Skin barrier: gingerols stimulate the synthesis of ceramides (components of the lipid barrier)
• Anti-Staphylococci: documented antibacterial activity against Staphylococcus aureus (colonizes 90% of atopic skin)

Oral vs topical

Both paths are studied:

• Oral: reduction of systemic Th2 inflammation (applicable via INTI Drink)
• Topical: Ginger-based gels show a reduction in itching and redness when applied locally (in vitro studies and a small pilot study 2023)

Difference from psoriasis

Atopic dermatitis is Th2-dominant, psoriasis is Th1/Th17-dominant. Ginger works on both pathways, but with slightly different targets. See ginger and psoriasis for Th17 inflammatory skin.

Anti-AD diet and role of ginger

AD is strongly influenced by diet and the intestine (skin-intestine axis):

• Avoid refined sugars (Th2 worsening via insulin) — hence the importance of zero sugar of INTI Drink (1.19g/100ml)
• Ginger like anti-inflammatory ginger digestive ginger and the microbiome
