Clinical Trial Summary

In this study, 60 depressed patients who meet the criteria will randomly be divided into a test group and a control group, with 30 patients in each group. The test group will be given Volatile oil of Cang-Ai (hereafter referred to as CAVO) for inhalation and the control group will be given Bergamot for inhalation. The observation indicators are that after one and two sessions of the intervention, the patients' blood pressure, heart rate, depression scale scores, and changes in functional near-infrared spectroscopy(fNIRS). This randomized controlled trial will be used to look at the clinical efficacy of CAVO in patients with depression.


Description:

Depression is a common psychiatric disorder characterised by persistent depressed mood, loss of interest and feelings of helplessness. Depression has the highest burden of illness of any mental illness and is the leading cause of disability. Currently, depression is usually treated with antidepressants as the first line of treatment, but because the pathophysiological mechanisms of depression are still unclear, the mechanisms of antidepressant treatment are unknown, and there is no objective way to predict efficacy, depression often requires multiple "trial and error treatments" before an effective treatment plan can be determined. Chemically synthesised drugs are widely used to treat depression, but side effects have become a bottleneck to their long-term use. As a result, natural products from medicinal plants, such as Essential oils or Volatile oils, have become research targets for the development of new drugs. Volatile oil of Cang-Ai is a component extracted from aromatic Chinese herbs such as Atractlodis Rhizoma, Herba Agastaches, Flos Caryophylli, which is commonly used clinically in the treatment of mood disorders. This study will use a randomised controlled study method. 60 patients with depression who attended the First Affiliated Hospital of Yunnan University of Traditional Chinese Medicine from March 2022 to September 2022 will be recruited. They will be randomly divided into a trial group and a control group, 30 patients in each group. The test group will be given Volatile oil of Cang-Ai for inhalation and the control group will be given Bergamot for inhalation. Ultimately, a number of indicators will be tested to assess the clinical efficacy of the volatile oil of Cang-Ai.
