Garlic – tasty but stinky. Super nice added to bolognese. But is that really all it’s good for? Not a chance. In actual fact, fresh garlic contains allicin, which is a potent antibiotic, antiviral, antifungal, and antibacterial. It’s been in use for at least 4,000 years. And modern medicine is finally paying attention.

Because allicin is an unstable and natural compound, superbugs like MRSA that are resistant to synthetic antibiotics have no resistance. Fast-acting, potent, and natural, garlic is an unbeatable home remedy. It’s quick, easy, and inexpensive to make, too. Garlic has a huge range of health benefits, aside from those listed here, and we’ll go over those in more detail in another post.

But here’s the rub – the allicin is unstable, so it loses its effectiveness after about 8 hours.

If you can stomach the taste, you can fill gel capsules with the garlic oil recipe below, but for general health maintenance and internal infections, many people choose to buy stabilized allicin or odorless garlic capsules.

We use this garlic oil recipe to treat cuts, scrapes, and any type of skin infection via topical application. It’s safe for humans and pets. However, if you plan to treat a dog, you should ensure they can’t lick the area, as ingesting too much garlic is bad for pooches. We’ve had great results clearing up a whole host of ailments and injuries, both internally and externally, using this recipe.


Finely chop and crush two garlic cloves to begin the release and activation of the allicin. Place it in an airtight container.
For the fastest results, pour half a teaspoon of vodka over the garlic. This acts as a carrier and draws out the allicin quicker. But it’s optional.
Next, add three tablespoons of virgin olive oil. Only use virgin olive oil. Other oils aren’t as effective. Additionally, olive oil is naturally soothing.
Close up the container and shake vigorously for 30 seconds. Refrigerate for an hour. Shake again, and it’s ready to use.


Always keep this mixture in the fridge. Left at room temperature, garlic oil can grow harmful bacteria like botulism.


Because allicin is unstable, it loses effectiveness after 8 to 12 hours, so you need to make a fresh batch daily.

How to Use Externally:

Clean the affected area with a warm, damp cloth. Apply the garlic oil with a clean cloth or an organic cotton pad. Make sure you don’t get any lumps of garlic on the area. Apply two to three times daily, until the ailment clears up.

If you’re using this on animals, particularly dogs, ensure they can’t lick the treated area.

Use your common sense. If you or your pets have a serious ailment, or the problem you’re trying to treat shows no improvement after two or three days, or symptoms get worse, seek medical or veterinary treatment. Don’t wait. The health of yourself, your loved ones, and your pets are too important.
