Hairy Gourd, Job's Tears and Walnut 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.

• 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
• 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

  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.
