Why people make this congee
Women, in particular, are often more susceptible to water retention than men — hormonal fluctuations, postpartum changes, and constitutional factors can all play a role. In traditional Chinese medicine thinking, two main patterns are often at work: a weakened spleen and stomach that cannot properly move fluids through the body, or a weakened kidney qi that cannot transform and circulate water. Adzuki beans have long been celebrated as a food-therapy ingredient for water retention — they are gentle, tasty, and easy to incorporate into daily eating. Cogongrass root (mao gen) adds a natural diuretic quality, helping the body move excess fluid and supporting urinary clarity. Together with brown rice, this congee is a simple, nourishing way to address puffiness associated with kidney or functional fluid retention, scanty or dark urine, or vaginal discharge caused by damp-heat.
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
