CBD Has Anti-Bacterial Properties And Can Even Kill Superbugs

Could a compound from the cannabis plant become a weapon in the war against drug-resistant superbugs? While there’s still a lot of research to do, that question is not quite as hippy-dippy ridiculous as it might have once sounded.

Cannabidiol , or CBD, has been touted for a wide variety of health benefits, most notably as a treatment for people with certain forms of epilepsy. Now, new research is showing that CBD is surprisingly effective at killing bacteria in a petri dish, including those responsible for many serious infections, such as staph and its drug-resistant sibling, MRSA. In fact, CBD even appears to be just as effective as widely used antibiotics at killing bacteria, such as Staphylococcus aureus and Streptococcus pneumoniae.

Presenting their findings at the annual meeting of the American Society for Microbiology, scientists from the University of Queensland suggest that their work shows how CBD could be used to develop new treatments against gram-positive bacterial infections and even superbugs that have become resistant to conventional antibiotics.

It’s worth noting that the study was conducted in collaboration with Botanix Pharmaceuticals, a biopharmaceutical company that produces CBD-based products.

“Given cannabidiol’s documented anti-inflammatory effects, existing safety data in humans, and potential for varied delivery routes, it is a promising new antibiotic worth further investigation,” said Dr Mark Blaskovich at the University of Queensland’s Institute for Molecular Bioscience’s Centre for Superbug Solutions, according to a press release.

“The combination of inherent antimicrobial activity and potential to reduce damage caused by the inflammatory response to infections is particularly attractive.”

CBD is a compound found in cannabis plants, but it’s non-psychoactive so it doesn’t make you high. A bunch of studies have also shown that it’s extremely well tolerated by humans, with very little risk of abuse or dependency, according to the World Health Organization. Many of its more ambitious claims are yet to be confirmed by scientific evidence.

Needless to say, this doesn’t mean you should be treating your infections with CBD oil or any other cannabis-related product. These findings have so far only been tested on the tissues of mice and in a petri dish, so it’s still very early days for the research. Equally, the researchers have no real grasp of the mechanism of action. It also remains unseen whether these effects will actually be seen in humans. After all, honey has well-known antimicrobial properties , but it’s hardly recommended to use it like Bactine on a cut.

Despite these limitations, the study goes to show how CBD is a largely unexplored realm for science. Although many of its more lofty claims have the potential to fall flat, there are undoubtedly some fascinating insights to uncover from this long-overlooked compound.

“What may be really exciting, but we don’t know yet, is how it works. If it kills bacteria by a new mechanism not used by existing antibiotics, that would be really exciting,” added Dr Blaskovich, according to i News.

CBD Might Work as an Antibiotic to Treat Bacterial Infections

Experiments showed cannabidiol can squash microbes that cause staph infections.


CBD, or cannabidiol, is growing in popularity as a stress-relieving wonder drug that may help ease anxiety, inflammation and pain. Many enthusiasts also say it can cure a smorgasbord of other conditions. CBD is a non-active ingredient in cannabis — it doesn’t get you high. And that’s helped retailers avoid legal problems while plopping the substance into all manner of products.

But does the CBD chemical craze carry any weight? There’s one surprising new way it just might. New research from the University of Queensland shows CBD may actually be an effective fighter against bacterial infections — although researchers don’t think you should disregard the doctor and start self-medicating anytime soon.

The findings were presented this week at ASM Microbe 2019 by Queensland research chemist Mark Blaskovich. His team carried out test tube experiments where cannabidiol effectively squandered strains of Staphylococcus aureus , including MRSA, VISA and VRSA, which cause staph infections and have become increasingly resistant to antibiotics over the years.

However, CBD was not effective on every type of bacteria. S. aureus are Gram positive strains, which, in general, don’t have an outer membrane. And that makes them easier to treat with antibiotics than Gram negative strains. Such bacteria cause infections like E. Coli , Salmonella and Chlamydia, and have an outer membrane that is tougher to penetrate, making it typically more resistant to antibiotics.

Blaskovich’s work was partially funded by an Australian drug company called Botanix Pharmaceuticals. The company’s stock rose sharply on the news.

But it’s actually not the first time researchers have found a link between CBD and antibiotic properties. A study was published in 1976 exploring the antibiotic effects of CBD and THC , finding that Gram negative strains were resistant to both. But since then, studies on the topic have been few and far between. And these days, well-funded antibiotic research is on the decline.

“There is very little research going on in antibiotics now compared to how it was 30 years ago,” Blaskovich says. With fewer pharmaceutical companies investing in the field, most of the interest comes from academics and independent companies.

Barriers and Breakthroughs

Blaskovich’s team is preparing to do another round of trials before moving on to tests in animals, and eventually humans, if all goes well. Then, results permitting, he wants to pursue approval from the FDA to market the drug as a topical antibiotic.

Marijuana has a checkered past in the United States, but with the FDA’s approval of CBD to orally treat a rare form of epilepsy last June , Blaskovich remains optimistic.

“The road to clinical trials (and) getting it approved is probably shorter than normal,” he says. The upcoming studies will also be completed in Australia, where laws about research on cannabis are more lax.

Despite the promising first tests, Blaskovich advises curious consumers to take caution.

“The results weren’t good enough to say yes … it works,” he says. “We don’t want people to try self-medicating.”

Antibacterial CBD Ointment: The Complete Guide

In this article, we check out the science behind antibacterial CBD ointment. Is it an effective treatment or just a fad? Here’s all you need to know and more.

Antibacterial CBD Ointment

Bacteria are all around us. They live in soil, in water, even on our skin and in our guts. These single-celled microorganisms have a highly complex relationship with human beings. Some are beneficial, even necessary for our health. However, some can cause extreme harm under certain conditions.

If the wrong kind of bacteria enters the bloodstream, they can cause severe infections and even death. For this reason, it is critical to keep wounds clean and free from bacteria. And this is where antibacterial CBD ointment comes into the picture.

Recent research has shed light on the antibacterial properties of CBD and other cannabis compounds.

Over the past few decades, research has shed light on the antibacterial properties of CBD and other cannabis compounds. Some studies even suggest that they could play a role in treating antibiotic-resistant strains such as MRSA (methicillin-resistant staphylococcus aureus).

Later, we’ll explain all about antibacterial CBD ointment and how it works. But first, let’s take a look at why you might want to use this product.

Preventing Bacterial Skin Infections

Millions of tiny bacteria live all over our skin. One of the most common strains is Staphylococcus aureus, sometimes simply known as staph.

Under normal circumstances, these bacteria do not pose a threat to our health. However, if they enter the bloodstream through a cut or bite, an infection can occur.

When bacteria enter the body, the immune system springs into action. It triggers a series of reactions, including increasing blood flow to the area. This allows white blood cells to travel to the injury more quickly to neutralize the threat.

This increase in blood flow causes the infected area to become red, hot, and swollen. These are the symptoms that we typically refer to as inflammation. It is a normal part of the immune response but can be extremely uncomfortable.

As the infection clears, white blood cells break down to form a white or yellow fluid called pus. It can cause the affected area to blister, weep, or crust over.

In most people, bacterial skin infections will heal by themselves within a few days. However, people with weak immune systems may struggle to clear the infection without the aid of antibiotics.

If the infection spreads throughout the blood to the internal organs, it can cause problems such as septicemia (blood poisoning). This condition can be dangerous, and in some cases, even fatal.

Therefore, it is important not to underestimate the risks of bacterial skin infections. Most doctors recommend cleaning all wounds and applying antibacterial ointment as soon as possible. Doing this should help to reduce the risk of a serious infection.

Aside from these infections, some other common bacterial skin infections include cellulitis and impetigo.

So, how could CBD ointment help with these common problems? Let’s look at the science behind the compound and its antibacterial properties.

The Antibacterial Properties of Cannabis and CBD

CBD is just one of the many chemicals that cannabis plants produce. It belongs to a class of compounds called cannabinoids. All plants in the species Cannabis sativa L. produce cannabinoids, including drug-type marijuana and industrial hemp.

The main difference is the concentrations of each cannabinoid that these plants produce. Marijuana tends to produce higher levels of the intoxicating cannabinoid, THC. On the other hand, industrial hemp produces more CBD and just trace amounts of THC.

Furthermore, THC and CBD are not the only chemicals in the plant that influence the human body. Cannabis also produces a range of other active compounds, including terpenes and flavonoids.

Research is ongoing, but it appears that all three classes of compounds could possess antibacterial properties. Here’s what we know so far:


Scientists were studying the antibacterial properties of cannabinoids as far back as the 1970s. A 1976 study for the Dutch journal Antonie Van Leeuwenhoek investigated the activity of CBD and THC against staphylococci and streptococci bacteria.

The results showed that the two cannabinoids inhibited the growth of both bacteria in broth, although their efficacy reduced in blood/serum. The research also suggested the compounds were effective against gram-positive but not gram-negative bacteria.

A later 2008 study for the Journal of Natural Products supported these results. It suggested that cannabinoids have the potential to fight MRSA. The study looked at a full range of cannabinoids, including:

Although the study determined that these cannabinoids were effective, its authors were unable to pinpoint their precise mechanism of action.


Terpenes are oily compounds that give cannabis its distinctive aroma. In nature, their role is to protect the plant against various pests and diseases. Therefore, it is unsurprising that terpenes seem to play a vital role in the antibacterial properties of cannabis.

A 2001 study for Flavour and Fragrance Journal looked at the antibacterial properties of industrial hemp. It included the essential oils of five different cultivars (strains) of the plant. The essential oils contained a wide variety of terpenes, including:

  • Alpha-pinene
  • Myrcene
  • Trans-beta-ocimene
  • Alpha-terpinolene
  • Trans-caryophyllene
  • Alpha-humulene

Each cultivar contained different levels of terpenes, and each had varying degrees of antibacterial activity.

The authors tested a total of 21 different microorganisms, and the essential oils were effective against 11 of these. They concluded that industrial hemp has “modest” antimicrobial activity.

However, later studies such as this one for Fitoterapia and this one for Molecules showed more significant results. The latter concluded that hemp essential oils showed “good antibacterial activity” against gram-positive bacteria. Its authors attributed this in large part to the presence of terpenes.


Flavonoids are another vital component of cannabis. These chemicals are probably best-known for their health-boosting antioxidant effects. However, they may possess some antibacterial properties too.

A 2018 study for the Journal of Integrative Medicine took this idea a step further. Its results suggest that flavonoids could enhance the efficacy of other antibacterial substances. The research looked at extracts from Cannabis sativa, Thuja orientalis (a type of conifer), and Psidium guajava (guava).

The authors found that each plant extract possessed antibacterial properties on its own. However, when they mixed Cannabis sativa and Psidium guajava with Thuja orientalis, this significantly enhanced their effects.

The authors went on to state that the plants appeared to have a “profound synergism” with one another. They suggested that this phenomenon was probably due to high levels of flavonoids, including:

  • Quercetin
  • Gallic acid
  • Catechins

This synergy between compounds is of particular relevance when it comes to antibacterial CBD ointment. In the cannabis industry, it is commonly known as the ‘entourage effect.’

CBD Antibacterial Ointment and the Entourage Effect

The entourage effect is something that consumers should consider when purchasing CBD antibacterial ointment. This is because CBD products fall into three general categories:

  • Full-spectrum CBD
  • Broad-spectrum CBD
  • CBD isolate

Full-spectrum products contain a full range of cannabinoids, terpenes, and flavonoids. They may include some THC, although this is usually only present in trace amounts (under 0.3%). Since these products are the most complete and natural, they likely have the most synergy between their compounds.

Broad-spectrum products are similar to full-spectrum, but minus the THC. They contain the majority of cannabis compounds, allowing for some degree of the entourage effect to take place. Broad-spectrum CBD products are ideal for anyone wanting to utilize the synergy of whole-plant cannabis without the THC.

Anyone wishing to use CBD ointment for skin infections should choose a full-spectrum or broad-spectrum product.

Finally, CBD isolates are the purest form of CBD. They do not contain THC or any other cannabis compounds. While they may be beneficial for some conditions, their antibacterial properties will be limited.

Therefore, anyone wishing to use CBD ointment for skin infections should choose a full-spectrum or broad-spectrum product. Doing this will allow them to benefit from all of the antimicrobial chemicals in the cannabis plant, not just CBD.

Furthermore, consumers should only buy from reputable brands who publish third-party lab reports on their websites. These reports show that each product contains everything it should and nothing more. They also allow you to see a detailed breakdown of the product’s cannabinoid and terpene content.

Antibacterial CBD Ointment: Final Thoughts

Research shows that CBD and other cannabis compounds possess significant antibacterial activity. Furthermore, the cannabinoids, terpenes, and flavonoids in the plant may work together to provide an enhanced, synergistic effect.

Therefore, when choosing a CBD antibacterial ointment, it is best to opt for a full-spectrum product. Doing this will mean that you benefit from all that cannabis has to offer, just as nature intended.

Although the existing studies are promising, it is critical to note that these were conducted in labs and not on human subjects. The effectiveness of CBD ointment for skin infections in the real world still needs to be confirmed.

Always consult a medical professional if you suspect you have a bacterial skin infection. This is especially important if you have low immunity, or your symptoms do not improve after a few days.

Your doctor will tell you the best course of action and whether antibacterial CBD ointment is appropriate for you.
