When using essential oils to treat cold sores, it is important to understand the risks. Some essential oils can be irritating to the skin and may damage the skin if they are used too much.
An allergic reaction is also possible when using essential oils. Itchiness, swelling, and a rash or hives at the site of application are signs of an allergic reaction.
If signs of an allergic reaction develop, people should stop using the oil immediately.
Diluting an essential oil with a carrier oil is necessary. Dilution means the carrier oils provide better absorption as well as less irritation to the skin.
Some carrier oils a person may wish to use to dilute essential oils include:
- coconut oil
- sweet almond oil
- olive oil
It is best to contact a doctor before trying essential oils to treat a cold sore. The doctor can advise on the suitability of the oil, and they can also recommend any other treatments that may help.
A person should also contact a doctor if cold sores keep returning, even if essential oils help to treat them. They may recommend antiviral medications for frequent cold sores.
It is best to seek medical advice if a person experiences symptoms of an allergic reaction after using essential oils. For a severe allergic reaction or anaphylaxis, seek immediate medical help.
Anaphylaxis: Symptoms and what to do
Anaphylaxis is a severe allergic reaction that can be life threatening. The symptoms develop suddenly and include:
- hives
- swelling of the face or mouth
- wheezing
- fast, shallow breathing
- a fast heart rate
- clammy skin
- anxiety or confusion
- dizziness
- vomiting
- blue or white lips
- fainting or loss of consciousness
If someone has these symptoms:
- Check whether they are carrying an epinephrine pen. If they are, follow the instructions on the side of the pen to use it.
- Dial 911 or the number of the nearest emergency department.
- Assist the person in moving from a sitting position to lying down. If they have vomited, turn them onto their side.
- Stay with them until the emergency services arrive.
Some people may need more than one epinephrine injection. If the symptoms do not improve in 5 to 15 minutes, or they come back, use a second pen if the person has one.
Some essential oils may help manage cold sore symptoms and encourage healing. While more research is necessary, some oils that may help include lavender oil, peppermint oil, eucalyptus oil, clove oil, and chamomile oil.
Always mix essential oils with a carrier oil before applying it to the skin. Before treating the cold sore, it is best to apply the oil to a small area of skin to see if an allergic reaction develops.
If cold sores occur frequently, it is also best to consult a doctor to find out if they recommend medical treatments.
