Chinese Yam, Carrot, Black Bean and Quail 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.

• Black soybeans · Randomized controlled trial, 100 participants · 2013
  Systolic blood pressure fell more in the black soy peptide group (-9.69 mm Hg) than in the placebo group (-2.91 mm Hg) after baseline adjustment. Plasma malondialdehyde decreased and superoxide dismutase activity increased compared with placebo.Limitation: Used an isolated peptide supplement rather than whole black soybeans, and followed participants for only 8 weeks, so the results may not apply to food intake.PubMed 23924691
• 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
• 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
