5. Aloe Vera Gel
Aloe vera has been used for centuries to treat skin infections. It has natural antibacterial, antifungal and antiviral properties, making it an excellent choice for treating cold sores. Simply apply a generous dab of aloe vera gel to the sore and leave it to soak in. Don’t rub it as you could end up spreading the virus to other areas of your lips. If you don’t have a tube of aloe vera gel handy, you could also use a leaf from an aloe vera plant. Slit it lengthwise with a knife and scrape out the inner gel. Apply the gel, either the bought or the fresh, every few hours until the sore has healed completely.
