Bottle Gourd, Adzuki Bean and Barley Soup
traditionally used to support urinary comfort and reduce summer dampness
In short: Bottle Gourd, Adzuki Bean and Barley Soup is a soup that traditionally used to support urinary comfort and reduce summer dampness. It is most often made for cooling & summer heat, children's wellness, kidney & urinary wellness. Total time about 2 hr 15 min. Key ingredients: adzuki beans, hyacinth beans / flat beans, job's tears (coix), rock sugar.
Why people make this soup
When summer heat is at its peak, drinking too little water — especially for children — can quickly lead to dark, scanty urine or a burning sensation when going to the bathroom. This classic cooling soup pairs bottle gourd with adzuki beans, flat beans and barley for a broth that is mildly sweet, refreshing and very easy to drink. In traditional food therapy, this combination is associated with relieving summer heaviness and supporting the body’s natural urinary function. It is a family-friendly recipe, suitable for adults and children alike.
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.
- Adzuki beans
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 - Job's tears (coix)
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
