Biological, Functional and Network Pharmacological Exploration of Essential Oils in Treatment and Healthcare of Human Diseases

Abstract

Essential oils (EOs) are natural products with bioactive functions that are obtained from various plant species, including Lavandula angustifolia and plant parts, through extraction methods, such as hydro-distillation, steam distillation and cold pressing, which can be dated back to ancient Egyptian and Greek times. Although various EOs are effective for disease treatment, such as human infectious diseases and mental disorders, the specific pharmacological mechanisms remain unclear due to its complex composition. Previous studies have attempted to recruit pharmaceutical analysis techniques, such as HPLC and MALDI-TOF, in order to elucidate the compositions of EOs. However, these have provided limited information on the mechanism of the bioactive functions of EOs. In recent years, network pharmacology has emerged as a convenient and appropriate approach to study the molecular mechanism of traditional medicines. To date, there is a lack of updated reviews on the recent progress of network pharmacology in the field of interactions between EOs and human diseases. Therefore, the present study scrutinized recent and important literatures in the field of network pharmacology and EOs, aiming to provide a timely yet brief overview of EOs as a potential treatment for diseases via network pharmacology, and facilitating the application of EOs as a complementary medicine and therapy for human diseases.

Bioactive Phyto-Compounds with Antimicrobial Effects and AI: Results of a Desk Research Study

“…The pharmacological efficacy of multicomponent systems increases as a result of intramolecular interactions, resulting in a clinically significant synergistic effect. Network pharmacology is a promising method for elucidating the relationship while analyzing the results from a holistic perspective [ 16 ].…”

Exploring the Molecular Mechanisms and Therapeutic Potentials of Essential Oils: A Systems Biology Approach

“…They protect plants from the attack of pathogenic microorganisms and play an influential role in humans for the treatment of chronic diseases and the improvement of various mental health syndromes. 3 Being small and lipophilic, they easily penetrate the skin, exhibit rapid distribution across tissues and organs, and demonstrate swift action. Consequently, essential oils are widely used in traditional remedies for various applications.…”
