Herpes simplexI remember years ago a patient telling me that he cured a “cancerous” lesion on his dog’s leg using cannabis oil. At the time I thought it was fanciful and interesting but probably coincidental at best.

However, it appears that the topical use of cannabis oil (CO) may indeed be curative in many dermatologic applications. It makes sense because phytocannabinoids are potent anti-inflammatory compounds. They help to reduce the immune response that makes a condition painful or uncomfortable. Certain cannabinoids can also arrest the replication of, or sometimes kill, both viruses and bacteria. Often times dermatologists will combine a corticosteroid such as prednisone with an antiviral like acyclovir to treat a superficial herpes infection (except in the eye). Such an approach reduces the symptoms of infection while killing the virus.

CO therefore mimics medical ointments that combine both a corticosteroid (prednisone or hydrocortisone) and an antiviral or antibiotic. The only problem is that medical transdermal products are usually available only by prescription. Even the veterinarian salves require an office visit. They can be costly. Perhaps you don’t really need to see a doctor. Let’s look at some alarming herpes statistics.


Worldwide, the rate of HSV infection– counting both (HSV-1) and (HSV-2) – is around 90%. About 1 in 6 Americans (16.2%) aged 14 to 49 is infected with HSV-2. HSV-2 prevalence was nearly twice as high among women (20.9%) than men (11.5%), and was more than three times higher among blacks (39.2%) than non-Hispanic whites (12.3%)[1].

In the US for example, a miniature tube of acyclovir cream for patients with herpes sells for a ridiculous $30 or more and lasts about as long as it takes to read this article. Anyone with “herpes” may run through a half-dozen tubes per year.

Well, what if I told you that you can make a powerful prescription-like balm that’s perfect for treating superficial viral infections like a herpes cold sore on your lip or genitals? At the end of this article I’ll include one for you that’s super simple to make. The below listed recipe uses a small amount of pot simply dissolved in alcohol. That’s one version. Now that you can buy CBD oil online, you may also wish to try CBD oil. I have seen CBD oil literally arrest herpes lesions almost on contact. In fact, the performance of CBD oil is far BETTER than acyclovir cream and a fraction of the cost.


The research on using THC to treat herpes simplex is Spartan at best but there’s enough to support a trial of such an approach. As far back as 1980 Blevins et al demonstrated that herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) failed to replicate in human cell cultures when exposed to a solution of delta 9 THC.[2]

Seven years later Mishkin and Cabral demonstrated that micromolar concentrations of Delta 9 THC inhibits the synthesis, maturation, and cellular transport of HSV2-specified glycoproteins.[3] Translated, it basically means that replication of HSV was arrested. Decreased expression of virus glycoproteins may be valuable in the human immune response to HSV infection.

Supporting documentation came from a publication released in 1991 which stated: …the data suggest that THC preferentially reduces the infectivity of the enveloped herpes simplex virus.[4]

Right, so we now know that THC can inhibit HSV replication. What we don’t know, since studies are not yet available, is if other phytocannabinoids, such as CBD, will perform the same way. We also need clinical trials on humans to completely verify if transdermal cannabis is a valuable tool in treating HSV infection. But we do have anecdotal cases such as the ones I am referring to in this article.

But why wait for science to catch up? Look at the accumulating data on cannabis oil and the treatment of cancers-initially most of it appeared as self-reported case studies. Why not try it for yourself and see if it helps?

What I recommend is to try hash oil, CBD oil, or a topical application of the formula given below. At the very first hint of a herpes outbreak, either a cold sore or a genital lesion, apply a generous amount onto the area affected and rub it in. Do this two to three times a day or as often as needed to halt symptoms. What you’ll experience is nothing short of amazing. Within two days or less, especially if caught very early in the prodromal phase, you will no longer have a herpes infection. For anyone reading this article who is impressed with their individual results please use the comments section to notify me.


Derma Dragon – Tincture of Marijuana[5]

*For External Use Only*

The Recipe:

1 Ounce of 70% Isopropyl alcohol (rubbing alcohol)

(Grain alcohol, such as 190 proof Everclear, may work as well but I’ve always used rubbing alcohol. Inexpensive and easy to come by.)

½ Gram Marijuana

(The better the quality, the stronger the tincture.)

1 Glass or plastic container with a tight fitting lid (2-ounce size works well.)

(Most people recommend a dark container. I’ve always used clear ones.)

Pour the alcohol into the container, add the marijuana (Don’t grind it up. Loses too much THC.), and put on the lid. Let the mixture sit for at least 2 weeks, but preferably 4, giving an occasional shake to stir things up.
