Why people make this drink
When a family member faces surgery that requires general anaesthesia, many readers in Nourilo’s community prepare a flask of this simple radish and chen pi water to bring to the hospital. In Nourilo’s own experience with a relative’s operation, the patient drank a large thermos of this water as soon as she was allowed fluids — and urinated freely not long after, which is traditionally understood to signal that the anaesthetic is moving out of the body. By contrast, a neighbour in the same ward who had not drunk it struggled for some time before she could urinate at all.
This is, in Nourilo’s words, an extremely easy drink to prepare in advance and bring along. The key is to sip it slowly and steadily, in small mouthfuls, and to drink as much as you comfortably can.
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
