The encouraging results indicate the essential oil of E. globulus leaves might be exploited as natural antibiotic for the treatment of several infectious diseases caused by these two germs, and could be useful in understanding the relations between traditional cures and current medicines.

Essential oils (EO) of eucalyptus (Eucalyptus globulus), thymus (Thymus capitatus L.) pirul (Schinus molle L.) were evaluated for their efficacy to control Aspergillus parasiticus and Fusarium moniliforme growth and their ability to produce mycotoxins. The IC50 was used to evaluate spore germination kinetic and mycotoxin production. Also, spore viability was evaluated by the MTT assay. All EO had an effect on the radial growth of both species.

  1. Hi. What do you think of using essential oils as cologne (applying to wrist & neck daily)? What would you use as fragrance that’s easy to get today? Thanks.

    • I do not apply any essential oil or body sprays. I just spray a good perfume over the cloth.
      Natural essential oils such as lavender oil, jasmine oil etc – 2 – 3 drops is fine to use over skin provided the person is not allergic to them.
