Based on this review, we could observe that the main inflammatory mediators and oxidative stress markers analyzed were TNF-α, IL-8, IL-6, IL-1β, nuclear factor kappa β, MDA, and MPO. However, it is necessary to increase the rigor of study design and data, in order to have studies that are more homogeneous and with appropriate methodological quality.
Carvacrol has a high therapeutic potential, with in vitro studies showing promising results in different
cellular models using a variety of methodological designs. Therefore, the objective of this study was to conduct a
systematic review to analyze the pharmacological effects of carvacrol in in vitro studies. A comprehensive search
of the literature was made using four databases: Science Direct, Scopus, MEDLINE-PubMed, and Web of Science
using different combinations of the following keywords: carvacrol, drug therapy, therapeutic uses, in vitro
study. The search of the databases was for studies conducted in the period up to and including September 2016. A
total of 3,269 studies were initially identified, with only 31 meeting the inclusion criteria. The included studies
contained a variety of in vitro models able to determine the properties of Carvacrol. The following properties of
Carvacrol were identified: antimicrobial (7 studies), bactericidal (4), bactericidal and antifungal (1), antiinflammatory
(4), anticancer (4), mutagenic (4), antioxidant (3), antifungal (3), antidepressant (1), as a modulator
of nerve impulses (1) and an immunological modulator (1). The In vitro studies with Carvacrol included in this
review showed a diversity of models and confirmed the therapeutic potential of this product in relation to several
diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
