Kudzu Root, Adzuki Bean and Poria Soup

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.

• Kudzu root · Randomized controlled trial, 20 participants · 2015
  The kudzu group reduced intake from 3.0 to 1.9 beers after treatment, while the placebo group rose from 2.7 to 3.4. Kudzu-treated participants also drank more slowly.Limitation: Very small sample (10 per group) with a single dose in a laboratory setting, so results may not carry over to everyday drinking.PubMed 26048637 · 2 more kudzu root 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
• Tangerine peel · Randomized controlled trial, 72 participants · 2025
  The tangerine peel drink group showed significant reductions in body weight and triglycerides after the intervention compared with the control group (p < 0.05). Safety markers showed no adverse effects. Gut microbiota and serum metabolite profiles also differed.Limitation: Small pilot trial with only 55 of 72 participants completing. The fermented product is not the same as plain tangerine peel, and the control group is not described.PubMed 40225325
