Misophonia is a disorder characterized by a high level of annoyance with certain sounds. Exposure to these sounds causes physical symptoms characterized by anger, aggression, helplessness, overwhelm, and stimulation of the sympathetic nervous system. These emotional and physical reactions can lead to a decline in family relationships, work and school productivity, withdrawal from social relationships, and even suicide. There is limited empirical evidence evaluating the efficacy of therapeutic approaches to misophonia. This limited empirical evidence consists of pharmacological agents such as selective serotonin reuptake inhibitors, stimulants, antipsychotics, and β-Blockers, as well as cognitive behavioral therapy, acceptance and commitment therapy, and dialectical behavior therapy. Complementary therapies are important because of their potential efficacy, tolerability, possible non-interference, and low cost. The fact that lavender has anxiolytic, antidepressant, neuroprotective, and anti-inflammatory properties may affect the emotional and physical responses elicited by misophonia. Therefore, within the scope of the study, misophonia individuals will be divided into two groups; one group will use lavender tea for 14 days and the other group will form a waiting list. The study data will be collected by 'Information Collection Form', 'Misophonia Scale', 'Beck Depression Inventory-II', 'Anxiety Rating Scale', and 'Trait Anger Scale'. SPSS 25.0 software will be used to analyze the data obtained from the research. Considering the limitations of therapeutic approaches for misophonia, testing the effectiveness of lavender in reducing misophonia symptoms will make an important contribution to the literature.
