The reason potato slices can reduce swelling

The principle behind using potato slices to reduce swelling lies in the fact that potatoes are rich in potassium, which helps expel excess sodium and water from the body. However, if there is broken skin or improper application, it may lead to infection. Patients are advised to adopt scientifically sound and appropriate methods for reducing swelling to avoid physical discomfort.

Potatoes are a common vegetable containing abundant potassium. Because they create a relatively hypertonic environment compared to subcutaneous edema, they not only assist the body in eliminating retained sodium but also help remove excess fluid, thereby achieving a de-swelling effect. Potatoes are considered a food with neutral and slightly cooling properties. In traditional Chinese dietary therapy, they are believed to offer benefits such as beautifying the skin, anti-aging, detoxification, anti-inflammation, and promoting blood circulation to reduce swelling. While potatoes do possess some anti-inflammatory properties, their effectiveness is limited. Although they can be used for mild inflammation, severe inflammation may cause local skin irritation, worsening swelling, or even lead to infection. Therefore, timely medical treatment should not be delayed—patients should seek prompt medical attention at a hospital.

Using potato slices to alleviate swelling is generally considered a home remedy. When localized swelling occurs, patients should not arbitrarily apply folk remedies, as this may interfere with proper treatment. Swelling should be treated according to its specific cause. For newly developed swelling, initial management often includes local cold compresses to promote reduction. After 48 hours, gradual therapeutic measures can be introduced to enhance blood circulation, which further aids in resolving the swelling.

If the affected area shows redness, swelling, and is accompanied by pain, patients are advised to promptly visit the surgery department at a hospital for wound debridement. The affected area should be disinfected with povidone-iodine solution to reduce bacterial growth and support recovery. Medication should be taken strictly according to medical advice based on the severity of the condition.
