Essential Oils for Enhancing QOL in ASD

The purpose of the study is to evaluate the use of two fragrant oil formulations to enhance quality of life by increasing relaxation and sleep quality in children with Autism Spectrum Disorder (ASD). Essential oils (aromatic oils extracted from plant parts) are routinely used by the public and are available on the market. Investigators are conducting this study because it is unknown whether the essential oils formulations will be safe and effective for helping children with ASD relax and sleep. To participate in this study children must be between 3-9 years of age and have been diagnosed with Autism Spectrum Disorder. Approximately 40 children will be screened to enroll 28 children and their families in the study. In a double-blind crossover study, participants will be randomized to treatment order. All participants will receive both fragrant oil blends. Those randomized will receive one fragrant oil blend for 3 months, with a 1-month "washout" period in between and then start the second fragrant oil blend in the last 3 months. The treatment orders are A/C and C/A. Study participation will last for 7 months. There will be one screening visit (about 5 hours long, which can be split into 2 visits), two baseline visits (about 2 hours each), two endpoint visits (2 hours each) and 5 other clinic visits (each 45-60 minutes). Visits will take place at the OSU Nisonger Center and the OSU General Clinical Research Center.
