Every day we discover more positive health benefits of using the natural medicinal plant cannabis (marijuana). Many of you may have heard of the devastating effects on some patients of methicillin-resistant Staphylococcus aureus (MRSA). This is a condition which resists nearly all standard antibiotics and can be deadly.
This study examined the antimicrobial activity of Cannabis sativa, Thuja orientalis and Psidium guajava leaf extracts against MRSA. Each of the MRSA isolates had been shown to be resistant to methicillin, penicillin, oxacillin and cefoxitin.
Used individually, a 50% extract of each plant leaf inhibited MRSA growth in this laboratory setting. That alone would be profound. But it was further found that when either C. sativa or P. guajava were combined with T. orientalis in combination of a 1:1 ratio, even greater zones of inhibition against MRSA growth occurred.
In their conclusion the authors state that the leaf extracts of C. sativa, T. orientalis and P. guajava had the potential for the control of both hospital and community acquired MRSA.
