Review: Role of the chemical compounds present in the essential oil and in the extract of Cordia verbenacea DC as an anti-inflammatory, antimicrobial and healing product: Essential oil - extract, anti-inflammatory, antimicrobial and healing evaluation

Cordia verbenacea DC is a plant whose geographical distribution is all over Brazil, but mainly on the country's coastal areas. It is used by folk medicine to treat inflammations and chronic pain with application of the raw extract of macerated leaves in the region of pain. This paper aims to provide an integrative review of the role of chemical compounds present in the extract and the essential oil of Cordia verbenacea DC for their anti-inflammatory, antimicrobial and healing properties. The extract of Cordia verbenacea DC is widely found within popular culture as teas, decoctions, infusions, pomades/creams for anti-inflammatory, antimicrobial and healing uses. Its extract is mainly composed of α-humulene, α-pinene, trans-caryophyllene, artemetin, spathulenol and allo-aromadrendene. The described effects of the chemical compounds found in the extract are applied to muscle bruising and myofascial pain, edema reduction and chronic tendonitis, when used topically (with a comercial product being marketed); and to rheumatic, neuralgic and arthritic processes, when used orally as an anti-ulcerative agent; as well as for its healing and analgesic properties when used topically or as infusion according to test results using animals. Besides its use in chronic pain and topical application, in vitro studies have revealed the importance of antimicrobial action by inhibiting the bacterial growth of the components present in the Cordia verbenacea DC extract. In addition to expanding knowledge about Cordia verbenacea, other studies are being developed with the extract and essential oil in order to expand knowledge about healing aspects of topical use. Although other studies are being conducted, the results presented in this analysis provide a rich database of the activities found in the compounds found in the extract and the essential oil, in addition to promoting knowledge of the best extraction method cited. Therefore, such studies constitute a preliminary source of information to encourage new pieces of research, species conservation, safe management of the species, use of the extract/essential oil and development of plant-based products.
