Kudzu Root & Job's Tears 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
• 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
• 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
