Special Issue Information
Dear Colleagues,
Research in recent decades has highlighted new roles for reactive oxygen species (ROS) in health and disease. Prolonged exposure to high ROS concentrations has been described as detrimental in several diseases (e.g., neurodegenerative, vascular, and inflammation health troubles, as well as diabetes mellitus and cancer), since it may lead to cellular damage. Although antioxidant supplementation seems to represent a way to reduce the high ROS concentrations, clinical studies have shown ineffective results, an effect probably due to low bioavailability and concentration of the antioxidant compounds. However, antioxidant supplementation has revealed benefits in the prevention of multiple diseases.
The World Plant Reports comprise 391,000 species of vascular plants, of which only 7.2% have been recorded for medicinal purposes. Medicinal and aromatic plants have been used worldwide in folk medicine or as food preservatives throughout human history; however, for most plant species, there is still a scarce scientific basis that relates their chemical composition with specific therapeutic effects, including antioxidant activity. Some scientific advances have allowed the understanding of the functional and medicinal relevance of this type of plant. They include biological, physicochemical, and functional characterization; applying botanical pharmacognosy and statistical tools to optimize the extraction of antioxidant compounds; drug delivery to improve bioavailability; metabolomics to study phytochemicals; and plant tissue culture as a sustainable management strategy. However, despite efforts made throughout the world to scientifically validate the use of medicinal and aromatic plants as a source of antioxidant compounds that help decrease the incidence of such diseases, further work is required.
This Special Issue of Plants will highlight the exploration of medicinal and aromatic plants used in different regions of the world as sources of antioxidant compounds, based on their phytochemistry, metabolomics, plant tissue culture, extraction conditions, drug delivery, and botanical pharmacognosy.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
