Roselle Chrysanthemum Tea (Luo Shen Hua Ju Hua Cha)

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.

• Chrysanthemum · Randomized controlled trial, 37 participants · 2023
  Compared with the high-fat meal alone, the extract group had lower postprandial glucose at 1 hour and higher antioxidant markers (T-AOC, SOD, GSH), with lower MDA. Incremental area under the curve did not differ significantly between groups.Limitation: Small sample of healthy young adults given a single high-fat meal, so longer-term effects and effects in people with metabolic conditions are unknown.PubMed 36677639 · 1 more chrysanthemum study
• 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
