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 · 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
• Job's tears (coix) · Randomized controlled trial · 2024
  Myeloperoxidase activity rose significantly in the placebo group after 8 weeks but showed no significant change in the adlay tea group. Vascular endothelial function improved in the adlay group, especially in those over 40.Limitation: Participants were healthy adults and the outcomes were surrogate markers, so the results say little about clinical disease outcomes. Tea is a polyphenol-rich extract, not whole grain.PubMed 38945894 · 2 more job's tears (coix) 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
