3. Use Baking Powder
A paste of baking powder and water will dry up blisters and soothe the itching. Add enough water to dry baking powder to create a paste, then apply it liberally to the affected area.
4. Try Epsom Salt
Another remedy for drying blisters and soothing inflammation is a paste made from Epsom salt and water. Apply directly to the affected area. Repeat as often as you wish.
5. Brew Some Tea
Brew a tea of lemon balm, an herb from the mint family that European studies suggest fights herpes viruses. To make it, boil 2 teaspoons dried herb in 1 cup boiling water. Use a cotton ball to dab it directly onto the affected areas. Some herbalists recommend bolstering the brew with rose oil or mints such as peppermint, spearmint, and sage.
