Signs and Symptoms of Cold Sores

Typical signs and symptoms of cold sores to watch out for include fevers, swollen lymph nodes in the neck, sore throats, a burning or tingling sensation around the nose and mouth, usually a few days before blisters appear.

Small painful blisters on the edge of mouth or around the lips that keep spreading and expanding are also a sign of cold sores.


Fewer Side Effects

Chances are you’ll be taking medication to relive pain and stop inflammation. Depending on the severity, you might have to take these medications for some time. 

Don’t we all know that every drug under the sun has side effects? Some of the common drug side effects are nausea, vomiting, drowsiness, diarrhea, lightheadedness, etc.

It is believed that these numerous side effects are caused by the many ingredients that make up conventional drugs. 

Since peppermint is made from natural or organic compounds, they are likely to cause minimal side effects or none at all. This explains why organic and natural products are becoming popular by the day.

No Resistance

Since people with low immunity are likely to suffer from viral infections often, they will be taking antivirals and other medication for a long time. This leads to the virus developing resistance to the drugs. 

Resistance to a drug means the causative organism is used to the drug and mutates to form another strain that the drug cannot identify. Peppermint has antiviral, antibacterial and antiseptic properties.

Topical Application

Most essential oils need to be applied topically as opposed to ingestion. It is advisable that you dilute peppermint with a milder carrier oil to reduce its potency and apply it directly on the cold sores. 

You can also mix it with a little water and apply it as a compress onto the cold sore. It takes a few weeks for the sores to disappear completely and calls for some patience. Don’t throw it away in 3 days that it is not working.

Disadvantages of Peppermint Oil

Peppermint is not supposed to be ingested as it can cause harmful side effects. All essential oils are meant to be applied topically or inhaled with a diffuser. When you ingest it, it leads to side effects like drowsiness, dehydration, allergy, lightheadedness, and others.

Also, if you are having a serious medical issue, do not hesitate to seek out a medical professional because there are limitations to solely relying on essential oils.
