Introduction
In general, potato slices have a certain anti-swelling effect. Before use, select fresh, plump potatoes that are not sprouted or green. Wash them thoroughly and cut into thin slices 2–3 mm thick, ensuring the surface is smooth and even. Clean the skin over the swollen area before application, then gently place the potato slice over it. Replace the slice every 15 to 20 minutes, avoiding prolonged application to prevent skin irritation.
Generally, potato slices have a certain anti-swelling effect. The specific analysis is as follows:
Potato slices are rich in potassium and plant starch. Potassium helps promote the reabsorption of local tissue fluid, thereby reducing swelling, while starch has a mild astringent effect that can alleviate local inflammatory responses. Applying fresh potato slices to swollen areas allows their moisture to hydrate the skin and facilitate ingredient penetration, effectively soothing minor swelling caused by light bumps, insect bites, or intravenous infusions. Due to their mild nature, potato slices rarely irritate the skin.
Before use, select fresh, plump potatoes that show no signs of sprouting or greening. Wash them thoroughly and cut into 2–3 mm thin slices, ensuring the surfaces are smooth and even. Clean the affected skin area before application, then gently place the potato slice over the swollen region. Replace the slice every 15–20 minutes to prevent skin discomfort from prolonged application. Store unused potato pieces in a sealed plastic bag in the refrigerator to prevent sprouting and spoilage. If swelling persists or is accompanied by pain, fever, or other symptoms, discontinue use immediately and seek medical evaluation for proper diagnosis and treatment.
