How to Use Tea Tree Oil for Cold Sores

Tea tree oil is a natural, powerful antiseptic and has been traditionally used to treat a variety of skin conditions. It has been found to be especially beneficial for cold sores. This guide will discuss what cold sores are, the health benefits of tea tree oil, and how to use it to treat cold sores.

What are Cold Sores

Cold sores, also known as fever blisters, are painful, fluid-filled blisters that appear on the lips, chin, and around the nose. They are caused by the herpes simplex virus and can often recur over time.

Health Benefits of Tea Tree Oil

Tea tree oil contains several natural antiseptic compounds, including terpinen-4-ol, which is known to kill bacteria and fungi. It also has anti-inflammatory and anti-viral properties, which make it a great choice for treating cold sores. It can help reduce swelling, redness, and discomfort associated with cold sores.

How to Use Tea Tree Oil for Cold Sores

Using tea tree oil for cold sores is easy and straightforward. Here are a few simple steps:

  • Dilute the Tea Tree Oil: Tea tree oil should always be diluted with a carrier oil, such as coconut or jojoba oil, before applying it to your skin. Start with a 1:4 ratio of tea tree oil to carrier oil, and adjust as needed.
  • Apply and Cover: Apply the diluted tea tree oil directly to the cold sore with a cotton swab. Cover the sore with a bandage and leave it on for 1 hour.
  • Repeat: Repeat the process up to 3 times a day. As the cold sore heals, the frequency of application can be reduced.

It is important to note that tea tree oil should not be taken orally, as it can be toxic when ingested.


Tea tree oil is a natural, safe, and effective remedy for cold sores. It has anti-viral and anti-inflammatory properties, which can help reduce the severity and duration of cold sores. Before using tea tree oil, it is important to dilute it with a carrier oil and to avoid ingesting it, as it can be toxic if swallowed. As always, it is best to consult a health care provider before treating any medical conditions, including cold sores.
