Potato slices can be used to treat hemorrhoids, using them externally to reduce swelling and pain. Since potato slices contain a lot of starch, applying them externally has a hypertonic effect, which reduces tissue permeability and reduces exudation, thus relieving local swelling and painful symptoms, and is a better treatment for local thrombosis or edema in hemorrhoids. You can cut potatoes into very thin slices for external application of hemorrhoids 3 times a day for about 15 minutes each time, or chop potatoes into mashed potatoes for external application of hemorrhoids, using the same method as before, if the symptoms are still not relieved or aggravated after 2-3 days of treatment, you need to go to the hospital in time.
