1. Peppermint Essential Oil

Peppermint has a strong antiviral effect and may fight well the virus that causes the blisters to erupt. Anytime a blister shows up and breaks, particles of the virus will be present in it and on your skin. Unfortunately, you cannot treat herpes simplex virus by ingesting peppermint oil as a prevention method. It only works if the virus resides outside your skin.

A lot of people used peppermint essential oil to treat cold sores, and they testified that they felt better and that the healing process of an outbreak was faster. Even scientific studies (like the one published in Phytomedicine, in 2013) certified that this oil can inhibit the development of both herpes simplex viruses, HSV1 and HSV2. The study demonstrated the antiviral effect in a proportion of 99% after three hours of virus incubation. You should use it right from the beginning, when you first notice any sign of a possible herpes episode, to get best results.


  • Clean the infected area to make room for the oil to act.
  • Soak a small cotton pad in cold water, and then pour a few drops of peppermint oil. This dilution is beneficial for your skin because it eliminates the probability of irritation.
  • Place the cotton pad on the blisters and keep there for a couple of minutes.
  • Rinse with warm water after that.
  • Repeat the process of applying the remedy twice a day until you get rid of the cold sore outbreak.

2. Geranium Essential Oil

Ancient Egyptians used geranium oil for keeping their skin healthy because it has anti-inflammatory and antibacterial properties. They passed away their knowledge from generation to generation and so modern people still use this herb to treat various skin conditions. It is a mild oil, similar to lavender one; it doesn’t have an irritating effect, and it isn’t toxic. Also, it can heal wounds and acts as an antiseptic and antidepressant. Because of these facts, geranium essential oil is a good candidate to treat a cold sore outbreak. Just like for the peppermint oil, the ideal use is a topical application.


  • Only wet a cotton swab and drip some oil drops.
  • Apply on the sore spot and leave it to act for three to five minutes.
  • You should clean the area after that with warm water and use a bit pf petroleum jelly.

Caution: Don’t use geranium oil if you are pregnant or breastfeeding because it may have an effect on the hormone secretions.
