Therapeutic Effect of Thyme (Thymus Vulgaris) Essential Oil on Patients with COVID۱۹: A Randomized Clinical Trial

 Background and Objective: SARS COV-۲ is a worldwide pandemic disease. There is currently no effective cure for this virus, but some types of herbs can be a good choice for reducing its symptoms. There are some reports that Thymus Vulgaris has a high antioxidant compounds effective in strengthening the immune system, as well as anti-virus effects to reduce the respiratory symptoms. Therefore, we speculated that Thymus Vulgaris could be useful for reducing some of the symptoms in patients suffering from COVID- ۱۹.  Materials and Methods: First, thyme essential oil was prepared and a questionnaire regarding the patients’ symptoms was designed. Then, ۸۳ patients with COVID-۱۹ were randomly selected and divided into control group and thyme receiving group (TRG). The questionnaire was completed and emphasized to consume ۵ mL of the syrup or essential oil three times per day. Finally, one week after the first visit, the questionnaire was completed again to determine the effects of thyme on the mentioned symptoms. Finally, the test results were reviewed and reported.  Results: The results one week after taking thyme showed that, the fever (p<۰.۰۲۷), dizziness (p<۰.۰۰۳), cough, dyspnea, muscular pain, headache, anorexia, weakness and lethargy, fatigue, and chest wall pain were significantly reduced (p<۰.۰۰۱). Also, BUN (p<۰.۰۰۴), neutrophil count (p<۰.۰۰۱), and calcium (p<۰.۰۳۴) decreased but, lymphocyte count was increased significantly (p<۰.۰۰۱).  Conclusion: Thyme plant which has high antioxidant properties, strengthens the immune system, and induces the antiviral effect could reduce the symptoms of coronavirus; therefore, it is recommended for reducing the symptoms of COVID-۱۹.
