29 Home Remedies to Get Rid Of Cold Sores

23. Try A Teabag Poultice

Another home remedy is using a teabag poultice, which is basically steeping a tea bag in hot water and allowing it cool completely. Then place the teabag on the affected area, either where a cold sore already is located or where you think one might occur. Leave the teabag on the area for at least ten minutes at a time, and do this between three to four times throughout the day, depending on the severity of the case. Most mention using Earl Grey as the best kind for cold sore treatments, and you can even cool the bag inside the ref before using it too.
