Author Guidelines


1.- Introduction
Journal of Ozone Therapy (JO3T) borns from the necessity of having a common place to publish scientific papers about the medical uses of ozone and its fundamentals that enhance the interchange of knowledge on these topics inside the scientific community.

2.- Official Language
As official journal of the World Federation on Ozone Therapy (WFOT), all articles should be sent in English language. We advice the authors to have a revision by a native English speaking colleague before sending the paper to the JO3T.
All articles can also be published in the native language of the authors as an addition to the official publication, if it is different from English. Authors must send a copy of the article to JO3T in the native language in a PDF file, including text, tables, images and all parts in a proper layout that will not be altered by the Production Editor.

3.- Article sections

Articles published in JO3T should fit one of the following formats (sections):

a) Original Articles.
b) Review Articles.
c) Opinion Articles.
d) Case Reports.
e) Proceedings/Meeting abstracts.
f) Letters to the Editor.
g) Editorial.

Please read the Section Policies for detailed information.

4.- Parts of the manuscript:

4.1. Previous information
a) With each new manuscript submission, authors must select the Category of the article: Original Article, Case Report, Review, etc.
b) The authors can send "Comments for the editor" describing the significance of the work, its uniqueness, and any similar work the authors reported previously.
