Effect of Thyme Oil on Respiratory Symptoms and Hemodynamic Parameters in COPD Patients

Overview

Chronic Obstructive Pulmonary Disease (COPD) is a high-prevalence, preventable and treatable disease characterized by abnormal respiratory symptoms and airway obstruction, often resulting from exposure to hazardous substances due to airway and/or alveolar abnormalities. The disease is an important problem with high morbidity and mortality rates all over the world and in our country. COPD is known as the third disease with a high mortality rate and the sixth disabling disease worldwide. The Global Burden of Disease Study reports 251 million cases of COPD worldwide in 2016. According to World Health Organization (WHO) data, it is estimated that 3.17 million deaths were caused by COPD in 2015. This number constitutes 5% of all deaths. More than 90% of these deaths occur in low- and middle-income countries.It has become common to use medicinal plants together with medical antiviral treatments to reduce the negative effects of COPD. Pulmonary elimination of thymol has been reported to have beneficial effects on respiratory diseases. Our research is the first to investigate in detail the effects of thyme oil on the symptoms and hemodynamic parameters of COPD. The widespread use of the thyme plant among patients shows that the research is important because it is an easily accessible, cheap and reliable essential oil.

Chronic obstructive pulmonary disease is treated with pharmacological and non-pharmacological methods. The first step of disease management is pharmacological treatment. Pharmacological treatment is generally preferred to reduce the frequency, duration and severity of symptoms experienced by the patient, reduce the acute exacerbation of the disease, improve the exercise capacity of the patients and increase the quality of life. Non-pharmacological treatments are; These are practices such as physical therapy, massage, relaxation techniques, meditation, reiki, yoga, prayer, multivitamins, herbal medicines, osteopathy, cryopathy, homeopathy, acupuncture, acupressure, reflexology, music therapy, visualization, hypnosis, and suggestion. It has become common to use medicinal plants together with medical antiviral treatments to reduce the negative effects of COPD. Among these, thyme is a plant from the Lamiaceae family that has no known significant side effects and is used for its healing effects. Thyme plant belongs to the mint family and the plant contains antioxidant compounds such as phenolic, eugenol, carvacrol and thymol. Pulmonary elimination of thymol has been reported to have beneficial effects on respiratory diseases. In the literature, Chabok et al. It has been reported that it improves gas exchange in the respiratory tract and increases oxygen saturation value. Similarly, Schönknecht et al. determined that thyme is a spasmolytic, antimicrobial, anti-inflammatory, immunomodulatory and antioxidant agent. Additionally, Oliveiro et al. reported that thyme could be an effective treatment of chronic diseases based on inflammatory processes in cases of morbidity and mortality in lung cancer patients.
