Why people make this soup

A lingering sweet sensation in the mouth — not from eating something sweet — is something many people experience without thinking much of it. In traditional Chinese medicine, this is associated with the spleen and digestive system. When the digestive system is out of balance, amylase levels in saliva can rise and stimulate the taste receptors on the tongue, creating that odd, mild sweetness. TCM further distinguishes between a “deficiency heat” pattern (fatigue, poor appetite, low energy) and an “excess heat” pattern (strong thirst, yellow urine, constipation). This soup is aimed at the excess heat type, using dried cabbage and preserved duck kidney to gently clear heat and support smooth digestion.

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
