Tangerine peel is rich in flavonoids, especially hesperidin and nobiletin, powerful antioxidant compounds. These substances help reduce inflammation, improve microcirculation and support the kidney's blood filtration process. In addition, the essential oil in tangerine peel also has a mild diuretic effect, helping the body eliminate waste and toxins through urine.
According to Dr. Michael Greger, clinical nutritionist (USA), author of many studies on plant-based foods: "Flavonoids from citrus peels have the ability to protect cells from oxidative stress, a factor directly related to chronic kidney dysfunction". He believes that taking advantage of dried tangerine peels to make herbal tea can bring certain benefits to kidney health if used regularly and moderately.
Traditional Eastern medicine has also long used tangerine peel (dry tangerine peel) to support digestion, reduce phlegm and regulate qi and blood, indirect factors that help reduce the burden on the kidneys.
However, experts recommend not abusing it. Tangerine peel needs to be washed, prioritizing tangerine sources without pesticide residues. People with chronic kidney disease, who are being treated with diuretics or specific drugs, should consult a doctor before regular use.
Using tangerine peel properly not only reduces food waste but also opens up a simple, natural kidney care direction right from the family kitchen.
