| Summary: | Currently the essential oils have been highlighted as promising sources of relevant natural
products for drug and cosmetic use because they are rich classes of secondary metabolites that confer
antioxidant activity to these oils. Antioxidants are responsible for the health benefit neutralizing the
actions of radical species that cause cancer, skin aging and cardiovascular disease. The research aimed to
conduct a survey on the importance of antioxidant present in the essential oils in promoting the health
benefits. Research was conducted by collecting information on antioxidant action of essential oils in
articles of scientific databases indexed in the Scielo, Google academic and Periodical Portal. So, it was
possible to realize that the literature indicates that the extraction of essential oil plants has become critical
to health due to the presence of substances such as phenolic compounds with antioxidant properties that
neutralize or slow the rate of oxidative reactions that occur in the organism, inhibiting the action of
oxidizing species, preventing the onset of diseases and contributing to greater longevity. So, it is apparent
the importance of researching and discovering new natural products such as essential oils from plants
containing substances in their composition with primary antioxidant potential for health promotion
against oxidative radical damage.
