Foods for Itchy Skin: What Traditional Practice Recommends
Most dietary advice for itchy skin is vague enough to be useless. Chinese dietary therapy is not — it names specific foods for itchy skin, and even gives preparations. Whether or not every item earns its place, the specificity is a welcome change from “avoid triggers”.
Foods for itchy skin: the list for hives and welts
- Winter melon rind
- Chrysanthemum, usually as a tea
- Papaya
- Ginger
- Rice vinegar
- Dried prunes
- Black sesame and black beans
- Pearl barley, taken as a tea
The traditional preparation is oddly specific: cook papaya, ginger and rice vinegar together until the vinegar dries off, then eat the ginger and papaya twice daily for at least ten days.
Some older sources also suggest a sea salt bath with salt rubbed over the welts. We would leave that one alone. Salt on inflamed, broken skin tends to aggravate it, and hives are irritable enough already.
The list for eczema and dry, irritated skin
- Potato, broccoli and dandelion
- Mung bean, often cooked with pearl barley as a tea
- Seaweed
- Water chestnut
- Winter melon and watermelon
- Cornsilk
Traditional sources also give topical suggestions here — grated fresh potato, honey, or mashed daikon applied to the skin. Please take care with those. Anything applied to skin that is broken, weeping or scratched open carries an infection risk, so keep them to intact skin and check with your doctor or pharmacist first. Our guide to natural eczema relief covers that condition in more depth.
Why the two lists differ
It is worth understanding why foods for itchy skin split into separate lists rather than one. Traditional practice reads hives and eczema differently. Hives move around, arrive suddenly and itch fiercely, which is described as wind. Eczema sits in one place, and is read according to whether the skin is dry and flaky or weeping and inflamed.
Therefore the food advice diverges. The hives list leans on things that disperse and settle. The eczema list leans on cooling and moistening. Working out which picture fits your skin matters more than following either list exactly.
What to reduce
The tradition is consistent on this across skin conditions. Reduce seafood, duck and goose, onions, garlic, sugar and alcohol, along with anything raw, spicy, fried or greasy. Meats and dairy are described as increasing irritation in the skin. Flaxseed oil goes the other way and is encouraged.
However, a note of realism. Do not strip your diet down on suspicion. Elimination diets run without guidance tend to narrow what you eat without settling the skin, and that is worth discussing with your doctor before you start cutting food groups.
Beyond the plate
- Cotton or silk rather than synthetics, which traditional advice specifies for ventilation
- Lukewarm showers, since heat is one of the most reliable aggravators
- Short nails, because scratching releases more histamine
- Protect your sleep, as itch is loudest when everything else is quiet
When to see a doctor
Call 000 for swelling of the lips, tongue, throat or face, or any difficulty breathing or swallowing. See a doctor for welts following a new medication, individual welts lasting more than 24 hours or leaving bruising, or hives with fever and joint pain. The healthdirect guide to hives covers it, and our page on acupuncture for hives explains treatment aimed at the pattern.
Frequently asked questions
Do these foods for itchy skin really work?
They are traditional recommendations rather than tested remedies, and results vary. Most are ordinary foods, so trying them costs little, but they work best alongside proper assessment rather than instead of it.
Is the papaya and vinegar preparation safe?
It is food, so for most people yes. If you have reflux, ulcers or take medication affected by vinegar, check with your doctor or pharmacist first.
Should I cut out dairy?
Traditional advice does reduce it for skin conditions. Try it for a few weeks rather than permanently, and keep your calcium intake in mind if you do.
