Winter Melon, Fresh Lotus Seed and Wild Duck 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.

• 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
• 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
• Ginger · Meta-analysis, 23 studies · 2022
  Overall, acute and delayed nausea and vomiting did not differ significantly between ginger and control groups. A subgroup taking 1 g/day or less for over four days had less acute vomiting (OR 0.30).Limitation: Clinical heterogeneity between trials required subgroup analyses, and the authors state that sufficiently large, high-quality RCTs are still needed.PubMed 36501010 · 3 more ginger studies
