Homemade Aged Tangerine Peel (Xin Hui Chen Pi)

Why people make this

Aged tangerine peel (chen pi) is a cornerstone of the Cantonese kitchen — a piece or two dropped into an everyday soup is traditionally said to help move qi and resolve phlegm. The Xin Hui winter tangerine is the prized source. The trick is patience: the greener the fresh peel, the more fragrant it becomes once dried and aged, and good peel needs at least three years of storage before use. And when an early cold and cough come on, that same peel becomes a quick warming tea with ginger and perilla.

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.

  • 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
  • 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
