Post-traumatic stress disorder (PTSD) symptoms can start at any time or during different situations after a traumatic event. However, few studies discuss the non-medical treatments in sensory treatments on how PTSD affects the emotions and life of patients. This study aims to explore how horticultural therapy and other sensory experiments impact PTSD patients. This research addresses how PTSD groups receive the benefits from experiencing the micro-horticultural therapy designed package — Two weeks of the sensory experiment conducted in PTSD group within the Michigan population. Participants answered questionnaires, including background questionnaire, response questionnaire, and DASS 21 questionnaire, as methods to track the healing improvement in their health conditions, career development, and interpersonal relationships. In addition, participants' self-reflection was explored after the experiment. Results demonstrated horticultural therapy's effect on the five senses and its impact on mental health. This research will positively propose Horticultural Therapy as a universal treatment for the PTSD population struggling with mental health and provide a future guideline for healthcare facilities.
