The research title’s “Antimicrobial activity of Cannabis sativa, Thuja orientalis and Psidium guajava leaf extracts against methicillin-resistant Staphylococcus aureus” . Published in the Journal of Integrative Medicine. Researchers demonstrated how ethanol-based tinctures containing crushed Cannabis Sativa leaves were able to inhibit methicillin-resistant Staphylococcus aureus (MRSA).
The interest of this new research lies in the ability to inhibit the growth of MRSA. A major pathogen in hospitals. MRSA infections caused by a type of staphylococcus bacteria that has become resistant to the antibiotics used to treat common staphylococcal infections. The MRSA bacterium had previously demonstrated resistance to the antibiotic methicillin, penicillin, oxacillin and cefoxitin.
Researchers used thin-layer chromatography technology to identify and study the bioactive molecules contained in each of the leaf extracts. For cannabis, the anti-sprouting properties relate to 5 distinct cannabinoids. As well as certain non-cannabinoid components of the plant, such as terpenoids. Results showed that leaf extracts inhibit the growth of MRSA. Other studies in the past showed that when cannabis leaf extracts combined with those of an evergreen conifer, Thuja orientalis, the effects were much greater.
It leads the researchers to conclude: “The ethanolic extract of C. So ,Sativa alone and in combination with T. orientalis provided two potential therapeutic agents for use against MRSA infections. »
