Fresh Lotus Leaf & Aged Yellow Cucumber Soup

Why people make this soup

In the traditional Chinese calendar, the solar term known as “Minor Heat” (Xiao Shu) marks the point when summer heat begins climbing seriously — hot, humid, and often stormy. This is precisely when home cooks in southern China reach for ingredients that help the body manage heat and humidity from the inside. This soup pairs the famously cooling fresh lotus leaf with the gentle hydrating effect of aged yellow cucumber, backed up by mung beans and pearl barley to support the digestive system. It is a refreshing pot that requires no special skill and suits the whole family.

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.

  • Mung beans · Randomized crossover trial, 20 participants · 2019
    Breath hydrogen and methane were higher after wheat than after rice or mung bean noodles. Bloating scores after mung bean did not differ significantly from wheat, and mung bean produced gas levels similar to rice.Limitation: Small sample of 20 patients, with single meals tested rather than habitual intake, so longer-term effects of mung bean on symptoms are unknown.PubMed 31484315 · 1 more mung beans study
  • 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
  • Red dates · Meta-analysis, 483 participants · 2025
    Jujube was associated with significantly lower BMI and triglycerides, and lower fasting blood sugar in people with type 2 diabetes. LDL and total cholesterol fell only in some subgroups. HDL, AST and ALT did not change significantly.Limitation: The authors state the overall quality of the evidence is limited, and results varied significantly by dose, treatment duration and disease type.PubMed 40399274 · 3 more red dates studies
