Today, licorice is used as a sweetener, but it has a long history of medicinal use for everything from sore throats to digestive issues. This root contains antiviral and immune-boosting properties, which helps your body in fighting the shingles virus. Licorice can be bought in powder form, which can be turned into a paste and applied directly to the affected skin. Alternately, you can make a tea from the licorice root, soak a cotton ball in it, and gently dab your blisters with the liquid. This can be applied as needed.
