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.

• Hawthorn · Randomized controlled trial, 41 participants · 2025
  Skin hydration scores improved more with hawthorn fruit than with placebo (p<0.05). Changes in other skin phenotypes and leukocyte telomere length were similar between groups. Genotype-specific effects were reported.Limitation: Small trial in which 36 completed follow-up; the genotype subgroup analyses are based on very few participants and are exploratory.PubMed 40573097 · 2 more hawthorn 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
• Honey · Meta-analysis, 14 studies · 2021
  Compared with usual care, honey was associated with lower combined symptom scores, cough frequency and cough severity. In two pooled placebo-controlled studies, the difference in combined symptoms was not statistically significant.Limitation: Only two studies compared honey with placebo, with high heterogeneity (I2=91%); the review calls for higher-quality placebo-controlled trials.PubMed 32817011 · 3 more honey studies
