Food-therapy guide
What to eat for eczema and itchy skin?
Short answer
For eczema and itchy skin, Cantonese food therapy often turns to soups that clear damp-heat or, for dry chronic itching, nourish blood and yin. Fresh Smilax, Mung Bean, and Coix Seed Soup is a practical choice for damp, heat-related itching, while Cabbage, Job's Tears & Mung Bean Soup pairs an everyday cooling soup with a separate external wash. For recurring dry eczema, Mulberry, Lily Bulb, Chinese Olive & Red Date Soup is traditionally used instead.
In Cantonese food therapy, itchy, inflamed skin that flares in hot or humid weather is often described as a damp-heat pattern. Long-standing eczema with dry, rough or thickened itchy skin, particularly in autumn and winter, may instead be associated with blood deficiency and wind-dryness.
The recipes below reflect those different patterns. Smilax, mung beans, Job's tears and other beans are traditionally used in damp-clearing soups, while mulberry and lily bulb appear in a gentler soup traditionally used for chronic dryness. Some recipes also include a separate external herbal wash for local itching.

How to choose
- For itchy eczema that feels linked to heat, humidity or damp weather, choose one of the fresh-smilax soups with mung beans, Job's tears or other beans.
- For dry, rough, thickened and repeatedly recurring eczema, particularly in autumn or winter, consider the Mulberry, Lily Bulb, Chinese Olive & Red Date Soup rather than automatically choosing the most cooling recipe.
- For a straightforward family soup with little herbal flavour, Smilax, Corn, Carrot, Adzuki and Hyacinth Bean Soup is described as suitable for all ages.
- If you want both an internal food-therapy recipe and an external option, Cabbage, Job's Tears & Mung Bean Soup comes with a separate herbal wash that is applied rather than drunk.
- If you have a cold-weak spleen-stomach, avoid the Fresh Smilax, Maranta and Three-Bean Soup; another smilax recipe suggests replacing mung beans with adzuki beans for people with a cold constitution.
When to be cautious
- Fresh Smilax, Maranta and Three-Bean Soup is cooling and should not be used by pregnant women or people described as having a cold-weak spleen-stomach.
- Any herbal wash included with a recipe is for external use only. Let it cool before applying, and do not rub or scratch the skin while applying it.
- For people with a cold constitution, the Fresh Smilax Root, Mung Bean, Hyacinth Bean & Job's Tears Pork Rib Soup notes that mung beans can be replaced with adzuki beans; that recipe should also be avoided during pregnancy and by people with liver-kidney yin deficiency.
- Itchy skin has many possible causes. If symptoms persist for several weeks, see a doctor.
Common questions
Which soup is best for eczema that gets worse in hot, humid weather?
A fresh-smilax soup with beans and Job's tears is the closest traditional match. Fresh Smilax Root, Adzuki Bean, Hyacinth Bean, Mung Bean, Barley and Pork Rib Soup is specifically associated with hot, humid summer weather and is traditionally used to clear heat and dampness when eczema, rashes or general itching flare.
What should I choose if my eczema is dry rather than damp?
For long-standing eczema with dry, rough, thickened and itchy skin, especially when it worsens in late autumn or winter, Mulberry, Lily Bulb, Chinese Olive & Red Date Soup is the better traditional fit among these recipes. Rather than focusing on clearing damp-heat, it is traditionally used to nourish blood and yin and support dry, chronically irritated skin.
Are any of these recipes suitable for children?
Several are described as family-friendly. Smilax, Corn, Carrot, Adzuki and Hyacinth Bean Soup is suitable for all ages, while the fresh-smilax, three-bean and Job's tears pork rib soup has little herbal flavour and is generally easy for children to drink. The external wash paired with the cabbage soup is described as gentle enough for infants, but it must never be drunk.
Can I use an external herbal wash as well as eating the soup?
The Cabbage, Job's Tears & Mung Bean Soup recipe specifically combines an internal soup with a separate traditional herbal wash for itchy skin. The wash is applied gently with cotton wool or a cotton swab without rubbing or scratching. It is for topical use only and must not be drunk; always allow it to cool before applying.
