Diffusing essential oils is one of the best way to support wellness in your home or workplace. From the great conifers to humble garden herbs, plants produce molecules to protect the health of their communities. The aromatic compounds that help plants flourish in their native habitats also support our bodies to heal and thrive.

In their native habitats, plants grow in communities. They must survive exposed to the natural elements, must compete with other plants, and must live in the midst of complex microbial and insect communities. Essential oils are part of a plant’s immune system, created by its evolutionary intelligence primarily for repelling pathogens. By harvesting and distilling their oils, we bring the immunological power of the plant communities into our communities…

One of the recent discoveries of aromatic research is that the antimicrobial effects of essential oils are most potent not when the oil is used in liquid form, as when applying tea tree to a fungal infection, but when pathogens are exposed to the vapors of the oils. This means that the most effective way of utilizing essential oils for reducing atmospheric contagion, neutralizing air-borne illnesses and enhancing immunity is through the use of aromatic diffusers, ionizers, and nebulizers. It has also been found that it is not necessary to have a high concentration of oil in the atmosphere for it to be effective; only a minimum amount of oil dispersed from a diffuser is necessary for optimum biological and immunological effects.”

    Anything kid friendly? I’ve read eucalyptus isn’t good to use with children Or just omit the eucalyptus?

      Hello Tara! These oils are categorized as non-toxic. I would not apply any of the oils directly to the skin as any essential oil applied to the skin without a carrier oil could result in a dermotoxic reaction. Diffusing these oils is always best and the safest way to use essential oils with children.
