Essential Oils of Plants Kill Viruses
Essential oils of plants "have shown promise as antiviral agents against several pathogenic viruses."
Enveloped viruses are very susceptible to essential oils. Some well know enveloped viruses are Colds, Flu and COVID19. Studies show essential oils sprayed into the air will continue to work for several hours continuing to reducing airborne pathogens.
Studies have shown various plant essential oils range from 85% - 100% effective against various flu strains A(H1N1, H1N2, H3N2), cold viruses and bacteria.
Some well known plant essential oils tested (in liquid form) that destroy viruses are cinnamon, tea tree, eucalyptus, lemon grass, lavender, and clove oils. This is only a small handful of highly effective essential oils against pathogens.
Dispersing an encapsulated planted based essential oil (EO) solution is safer, "as opposed to most antimicrobial agents currently used for air disinfection, EO's are low in toxicity". This allows EO's to disinfect the air while people are present. Antimicrobial activity increases when more than one essential oil is blended together.
Studies of essential oils (E.O.) of plants against COVID19 are just beginning to be explored. Due to this virus being an enveloped virus "essential oil components may interact with key protein targets of the 2019 severe acute respiratory syndrome coronavirus 2" causing destruction of the virus or preventing it's ability to bind as E.O's have done with other enveloped viruses.
Eucalyptus oil is showing promise against this virus but further studies need to be done.
