CBD extract demonstrated high antibacterial effect in treating salmonella typhimurium

01. 03. 2026

In a new foreign study from 2022, a microbiology expert team managed to demonstrate the highly antibacterial effect of CBD oil against salmonella. It appears that CBD extract could represent a more successful treatment than antibiotics.

What is salmonella?

Salmonella is an infectious disease that ranks among the most common diarrheal illnesses. It affects both children and adults. There are several types of salmonella, but the most common are salmonella enteritidis and salmonella typhimurium. The carrier is almost always infected animals, which means this bacteria enters the human organism through poorly processed food, whether meat, milk, or eggs.

The incubation period when symptoms of salmonella may appear is 8 to 48 hours. You'll recognize it by sudden nausea, vomiting, or watery stools. Fever, abdominal pain and cramps can also occur, and in extreme cases, internal organ damage may happen. The most ideal treatment is mineral metabolism adjustment. However, antibiotics are most commonly prescribed for salmonella bacteria, which is not the most sensible solution. We'll explain why below in the current study.

CBD extract causes reduction of Salmonella typhimurium and Salmonella newington bacteria growth

In the latest study, scientists decided to test the effects of CBD oil on salmonella bacterial disease. They cultured two salmonella types, the most common - salmonella typhimurium and another frequently occurring: salmonella newington. They prepared these cultures for research and combined them with CBD concentrations in ratios of 1.25, 0.125, and 0.0125 per ml. Significant bacterial growth reduction was observed 6 hours after treatment. Furthermore, it was proven that the higher the CBD dose, the stronger the antibacterial effect on salmonella.

Examining the Salmonella Bacterial Membrane

The research on CBD's effect on salmonella was conducted through fluorescent cell staining. The dye binds to DNA in this technique. The bacterial membrane does not allow the dye to pass, which means its integrity is disrupted. The results of this investigation confirmed that CBD led to membrane integrity degradation after just 5 minutes of treatment. In short, this means CBD can successfully damage the outer membrane of salmonella cells.

Salmonella Treatment with CBD Oil vs. Antibiotics

We mentioned earlier that antibiotic treatment is not very suitable for treating salmonella, yet it is still most recommended. Antibiotics are inappropriate because they only prolong the bacteria's excretion time from the human body. Additionally, antibiotic resistance develops. Although antibiotics should not be used to treat salmonella, the research confirmed that the antibiotic ampicillin can neutralize this bacteria to the same extent as CBD extract. One of many advantages of CBD extract is that, unlike antibiotics, it has no side effects and does not burden other organs. We can therefore deduce that CBD could potentially replace antibiotics.

Experts emphasize the need for increased attention to bacterial diseases. CBD oil in this specific study once again demonstrated its power against pathogens and bacteria. The study's conclusions could potentially serve to help the FDA approve additional cannabis-based medications that could help many patients. If you're fighting a bacterial infection, try consulting your doctor about using CBD oil - it might be the gentlest and most effective healing path for you.
