Why people make this soup
Watercress is one of those ingredients that Cantonese cooks have long had a deep affection for. Nourilo loves using it in wontons, fresh tofu rolls, and above all, in slow-cooked soups. Paired with dried figs and pig lung, this soup becomes a classic remedy for what traditional Chinese medicine describes as “lung and stomach heat” — the kind of internal warmth that shows up as dry mouth, bad breath, red eyes, or sluggish bowels.
Watercress is rich in vitamins and antioxidants and has a naturally cooling quality. Dried figs bring sweetness while traditionally supporting the intestines and soothing irritated tissues. Pig lung (a clean, mild organ meat when properly prepared) is used in the principle of “like nourishes like” — traditionally believed to support the respiratory system. A handful of apricot kernels and a piece of dried tangerine peel round out the flavour and function.
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
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
