Why people make this soup

When the air turns humid and heavy, many people notice their energy dipping, their limbs feeling puffy, or their digestion running sluggish. In traditional Chinese dietary wisdom, these sensations are often attributed to an excess of internal “dampness” — a state where the body’s fluid metabolism is a little out of balance. This simple five-ingredient soup has been used for generations as a mild, everyday remedy to bring things back into equilibrium. Because every ingredient is classified as neutral in nature, it suits the whole family — not just one constitution type.

Method

  1. Rinse all ingredients well. Soak in cold water for 1 hour to soften (this shortens cooking time and improves the final texture).
  2. Drain the soaking water. Place all ingredients in a pot with 1.8 L of fresh water.
  3. Bring to a boil over high heat, then reduce to a gentle simmer.
  4. Simmer uncovered (or with a lid slightly ajar) for 1 hour 30 minutes, until the beans and barley are tender and the broth is lightly thickened.
  5. Serve warm. You may add a pinch of salt if serving as a savoury soup, or a small piece of rock sugar if you prefer it lightly sweet.

Nourilo’s Tips

  • Meat is optional: add a few pieces of pork spare ribs or lean pork at step 2 for a heartier, more savoury soup — it does not change the food-therapy effect.
  • If you have no red adzuki beans, substitute one piece of dried tangerine peel (chen pi) to help the qi move and reduce bloating.
  • If someone in the family sweats heavily, add 15 g floating wheat (fu xiao mai) to the pot — it will not interfere with the dampness-clearing action.
  • This soup is gentle enough to drink 2–3 times per week when dampness is a recurring issue. Once symptoms ease, once a week for maintenance is plenty.
  • Not suitable during a cold or fever; people recovering from a cold with lingering weak digestion can use this soup to rebuild.

What studies say about the key ingredients

Traditional use is not the same as clinical proof. Here is the strongest human research we found for each ingredient, limitations included.

  • Lotus seeds · Randomized crossover trial, 10 participants · 2019
    Lotus seed meals had a low glycemic index (GI 21–51 across the lotus seed and adzuki bean meals), while several other starchy foods did not differ significantly from rice. Lotus seed's in vitro hydrolysis index was also lower than that of other test foods.Limitation: Only ten healthy participants and acute single-meal tests, so findings may not apply to people with diabetes or to long-term intake.PubMed 30875961
  • Job's tears (coix) · Randomized controlled trial · 2024
    Myeloperoxidase activity rose significantly in the placebo group after 8 weeks but showed no significant change in the adlay tea group. Vascular endothelial function improved in the adlay group, especially in those over 40.Limitation: Participants were healthy adults and the outcomes were surrogate markers, so the results say little about clinical disease outcomes. Tea is a polyphenol-rich extract, not whole grain.PubMed 38945894 · 2 more job's tears (coix) studies
  • Adzuki beans · Randomized crossover trial, 10 participants · 2019
    Adzuki bean meals had a low glycemic index (21–51 range reported with lotus seed), whereas other starchy foods did not differ significantly from rice. Adzuki bean hydrolysis index was lower than other test foods.Limitation: Only ten healthy participants and acute single-meal responses, so effects in people with diabetes or with regular intake are unknown.PubMed 30875961 · 1 more adzuki beans study
