CBD Kills Drug-Resistant Bacteria

This is a scientific guide.

Based on the latest medical studies.

  • know how CBD and antibiotics work together against Staph and Listeria bacteria
  • discover how CBD may save us from a future of drug-resistant superbugs

Let’s get started.

2020 CBD Research

Study Results: 

  • CBD used in combination with bacitracin (a topical antibiotic cream) resulted in a greater than 64 fold increase in the effectiveness of bacitracin against gram-positive bacteria such as Staphylococcus species, Listeria monocytogenes, and Enterococcus faecalis.  All are common and potential deadly human pathogens (1).                                                                   cannabidiol antibacterial results 
  • The addition of CBD to bacitracin had a synergistic effect which helped to more effectively kill drug-resistant bacteria strains (2).                                                                     cbd skincare benefit

Our summary: 

  • The findings of this study suggest that CBD is an effective “helper compound” for killing gram-positive bacteria (3).          
  • Because less antibiotic is needed to effectively treat infections when helper compounds like CBD are employed, the risk of developing antibiotic-resistant bacteria is decreased (4).

CBD Antibiotic Synergy: 

  • To determine the synergistic antibiotic effects of bacitracin (BAC) and CBD, a time-kill assay was performed to test whether or not CBD actually increased the effectiveness of bacitracin (5).                                             
  •  There was no synergistic effect for CBD and bacitracin against gram-negative bacterias such as Pseudomonas aeruginosaSalmonella typhimuriumKlebsiella pneumoniae, and Escherichia coli.                              

Conclusion:

  • Difficulty treating drug-resistant bacteria such as Staphylococcus aureus has sparked a search for new antibiotic compounds and treatment strategies (6).    cbd antibiotic treatment
