What is Terrasil?

Terrasil is a cold sore relief cream. The cream is designed to be applied when an outbreak is occurring. As such it is a symptomatic treatment, not a preventative. It contains a powerful antiseptic (benzalkonium chloride) which is designed to kill the virus, as well as be a skin protectant. The skin protectant is designed to sooth the skin and prevent secondary infections such as bacterial ones. Secondary infections are ones that can occur in the cracked skin of the cold sore.

Who is it for?

The manufacturer reports that Terrasil can be used on anyone over the age of 12. Medical advice should be sought for anyone under the age of 12 before applying.

How does it work?

Terrsil contains several moisturizing ingredients for the skin. They are:

  • Jojoba oil. Jojoba oil is an extremely nutrient rich and long lasting moisturizer. Its consistency allows it to penetrate into the tissues, carrying other active ingredients with it, and it can also repair cracked damaged skin.
  • Peppermint Oil. Peppermint oil is a traditional remedy for skin soreness and itching.
  • Palmarosa Oil. This oil also eases inflammation and moisturizes the skin.
  • Beewax. Beewax contains vitamin A which is important for repair of the skin and other membranes.

Terrsil also contains what the manufacturer calls “Activated Minerals”. This is a blend which includes Volcanic Clay (Bentonite), Magnesium Oxide and Zinc Oxide, which they claim “support the natural production of new, healthy skin cells, skin repair and reduced scarring.”

Terrasil should be applied 3-5 times a day until the cold sore is healed. It may be best to take Herdox to kill the virus and then use Terrasil to sooth the skin afterward and and heal the sore even faster.

How do I apply Terrasil?

You should wash your hands both before and after applying Terrasil. The manufacturer recommends applying the product as sore as you start feeling the initial “tingle” of the cold sore. Keep applying then 3-5 times a day until the cold sore is healed.

Research Results.

There are no articles published in the scientific literature specifically about Terrasil when searching in PubMed. This does not necessarily suggest there is anything wrong with the product, however it does mean the manufacturer’s claims have not been independently verified.

However the antiseptic used has been assessed in the scientific literature and has been shown to shorten healing times and decrease the discomfort associated for its effectiveness and has been shown to reduce both the time needed for healing and the discomfort of cold sores.[1] This would tend to support the manufacturer’s claims.

There are also a number of scientific articles referenced on the “Science” section of the manufacturer’s website that support the ingredients used in Terrasil for skin healing. While none of them specifically were about healing cold sores, they do support the general notion that the ingredients do in fact do what the manufacturer claims.

As part of our research we performed an online search for customer reviews. We were unable to find any reviews on Amazon or the major herpes/cold sore forums. This is not necessarily mean the product is bad, in fact it probably suggests that it is fine, as people who have had a bad experience are usually more motivated to leave a bad review.

The manufacturers site has two reviews, both 5 out of 5 stars. It is quite probable that they are genuine, however given the lack of other reviews you may wish to be cautious.


  • Low cost treatment
  • Available online to protect your privacy.
  • Mostly natural ingredients
  • Scientific support of its main antiseptic ingredient with cold sores.
  • Scientific support of its other ingredients in their general actions.
  • Available is a Max Strength form for persistent outbreaks.


  • Repeated application is needed.
  • Lack of independent feedback on the product.

Where to buy?

Terrasil can be purchased in many pharmacies or chemists, as well as online through Amazon.com. While these may be familiar or convenient, we recommend purchasing direct from the manufacturer for the following reasons:

  • Special offers – including (at the time of writing) buy 2, get 1 free or free shipping offers, plus other discounts.
  • A 90 risk free guarantee where you can return the product for any reason, even if you have used all of it.
  • Secure payment process.
  • A+ Better Business Bureau rating.

Terrasil can also be ordered from Canada, UK, Europe, Australia, New Zealand and South Africa (click here for international orders).


Terrasil has good scientific support for its ingredients and we haven’t found any negative reviews or scam reports online which is a good sign. It treats the symptoms of a herpes or cold sore outbreak, and is likely to speed healing and reduce pain.

Based on our research, it would seem that using a product like Herdox when the cold sore first breaks is best, then following it up with Terrasil to prevent cracking and speed healing after the Herdox has done its job. Purchasing Terrasil direct from the manufacturer will offer the best deal online.
