The aim of this study was to compare the efficacy and safety of the essential oil-based product in patients with mild to moderate symptomatic COVID-19 Positive infection confirmed by PCR. A computational simulation approach of the molecular interaction (binding) of the main components of essential oils exhibiting antiviral activity with known intracellular protein targets of SARS-CoV-2 (nsp5: Main Protease) was adopted as a rationale for this study. SARS-CoV-2, a single-stranded RNA virus, has four major structural proteins Spike (S), Membrane (M), Envelope glycoprotein (E) and Nucleocapsid (N) protein and non-structural proteins (nsp). These non-structural proteins, of which there are 16 in total in the genome of the virus, play key roles in the mechanisms of the virus life cycle, including replication, transcription, protein synthesis and modification of RNA. Main protease (Main protease, Mpro, 3CLpro), virus Since they are directly involved in the maturation of these nsp proteins, which have an important role in many mechanisms of the life cycle, they have been the target enzyme in the development of new antiviral drugs for the treatment of COVID-19. In this study, our main rationale is to investigate the effect of essential oils on nsp5: Main Protease enzyme activations.

The indiscriminate use of antimicrobial agents has led to the emergence of a number of drug-resistant bacteria, fungi and viruses. To overcome the increasing resistance of pathogenic microbes, more effective antimicrobial agents with new modes of action must be developed.

Medicinal plants used in traditional medicines to treat infectious diseases are an abundant source of new bioactive secondary metabolites. Therefore, in the last few years, various medicinal plants and plant extracts have been screened for their antimicrobial activities . Essential oils obtained from aromatic medicinal plants (e.g. fennel (Foeniculum vulgare), mint (Mentha piperita), thyme (Thymus vulgaris)) have been shown to have antimicrobial activity against gram-positive and gram-negative bacteria as well as yeasts, It has been reported to be active against fungi and viruses. They are mixtures of different lipophilic and volatile substances such as monoterpenes, sesquiterpenes and/or phenylpropanoids and have a pleasant odour. They are also part of the pre-formed defence system of higher plants are thought to be . Monoterpenes have been widely studied, especially for their antiviral properties.

Nowadays, the use of essential oils is becoming increasingly widespread both in pharmacies and in various stores. The use of essential oils for therapeutic purposes is expanding. The molecules that make up certain essential oils have shown various antiviral properties:

• Either by neutralising the virus before it enters the cell,
• By changing the capsid or envelope of the virus,
• Either by binding to receptors used by viruses and preventing their access to cells.

Herbal products are an important source of herbal remedies and other medicines. Essential oils have shown various pharmacological activities, such as antiviral activity, and have therefore been implicated in SARS-CoV- It has been suggested to have potential activity against 2. Essential oils can easily penetrate the viral membrane due to their lipophilicity and can cause rupture of the viral membrane.

In addition, crude essential oils often have many active components that can act on different parts of the virus, including cell entry, translation, transcription and assembly. Anti-inflammatory, immune regulation on the respiratory system of the host, have other beneficial pharmacological effects, including bronchiectasis and mucolytics.

Essential oils have many advantages because they promise volatile antiviral molecules, making them useful either alone or in combination with other chemotherapeutic drugs, making them potential drug targets for the prevention and treatment of COVID-19.

In this study, a computational simulation approach of the molecular interaction (binding) of the main components of essential oils exhibiting antiviral activity with known intracellular protein targets of SARS-CoV-2 (nsp5: Master Protease) was adopted as a rationale. A single-chain.

The RNA virus SARS-CoV-2 has four main structural proteins Spike (S), Membrane (M), Envelope glycoprotein (E) and Nucleoapsid (N) proteins and non-structural proteins (nsp) .

These non-structural proteins, of which there are 16 in total in the genome of the virus, play a key role in the mechanisms of the virus life cycle, including replication, transcription, protein synthesis and modification of RNA. Main protease (Mpro, 3CLpro) has been the target enzyme for the development of new antiviral drugs for the treatment of COVID-19 , as they are directly involved in the maturation of these nsp proteins, which have an important role in many mechanisms of the virus life cycle. Our main rationale in this study is to investigate the effect of essential oils on nsp5: Main Protease enzyme activations.
