Study: Cannabis Leaves Possess Anti-Bacterial Activity Against MRSA

INDIA: Ethanol-based tinctures containing crushed cannabis leaves provide anti-bacterial effects against methicillin-resistant Staphylococcus aureus (MRSA), according to data published in the Journal of Integrative Medicine. Strains of the MRSA bacterium are often resistant to antibiotic treatment and can be associated with life-threatening infections, such as septic shock and severe pneumonia.

A team of researchers from India assessed the antimicrobial activities of cannabis leaf extracts, along with extracts from the leaves of the plants Thuja orientalis (a form of cypress) and Psidium guajava(lemon guava), against MRSA.

Authors reported that each of the individual extracts inhibited MRSA growth, but that these effects were more profound when cannabis was used in combination with Thuja orientalis. They concluded, “Ethanolic extract of C. sativa alone and in combination with T. orientalis provided two potential therapeutic agents for use against MRSA infections.”

Prior studies have demonstrated that constituents in the cannabis plant possess potent antibacterial and antifungal properties which are capable of halting of the spread of MRSA and malaria under controlled conditions.

How Hemp Was Outlawed In India

INDIA:  Cannabis, the plant from which bhang, ganja and hashish come, has been regarded a traditional intoxicant in India. And yet it is outlawed in its homeland.

Around the end of the 19th century, the British imperial government in India wanted to import Scotch whisky. This was also the time when resentment against the colonial power was gathering critical mass. Hence, there were protests — bhang and ganja, argued some, were indigenous intoxicants; alcohol, it was claimed, was alien to Indian culture. [Read more…]
