Coriander oil can fight MRSA, E.Coli and salmonella

Coriander is a natural antibiotic

Researchers have found coriander oil is resistant to a range of different toxic bacteria, making it an ideal treatment of MRSA, E.Coli, salmonella and other strains of food poisoning.

The herb’s oil has long been used as a medicinal aid, thought to relieve pain and cramps, suppress nausea and help improve digestion.

However, Portuguese scientists have successfully tested the oil as a treatment against 12 lethal bacteria and now believe it could be used as a natural antibiotic.

They found a solution containing less than 1.6 percent of the oil was able to slow the growth of, if not destroy, MRSA, E. Coli, salmonella and Bacillus cereus.

It did this by destroying the outer membrane of the bacterial cells which then leads to their death.

Dr Fernanda Domingues, who co-authored the study which appeared in the Journal of Medical Microbiology, said: “We envisage the use of coriander in lotions, mouth rinses and even pills, to fight multidrug-resistant bacterial infections that otherwise could not be life.”

Although the initial results of the study were promising, the authors realise more research on the topic is needed.  

“These results are noteworthy and justify the use of this plant, not only as a food flavouring agent, but also as a food preservative in order to prevent bacterial spoilage of foods,” they said.

“However, this research needs further enlightenment in order to evaluate the suitability of these remarkable antibacterial properties in practical applications.”
