Huai Shan, Poria, Lotus Seed and Euryale Double-Steamed Free-Range Chicken

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
• Walnuts · Randomized controlled trial, 305 participants · 2019
  Office systolic BP changed by -4.61 mm Hg with walnuts versus -0.59 mm Hg in controls (P=0.051); 24-hour ambulatory systolic BP difference was not significant (P=0.111). No diastolic BP changes were observed.Limitation: Only 236 of 305 participants (75%) completed the study, and the main between-group differences did not reach conventional significance.PubMed 30879358 · 2 more walnuts studies
• 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
