The forest healing system is an important topic of alternative therapy in recent years. To study the influence of Forest therapy, the establishment of a pilot experimental model system in which both environmental factors and type of activity are necessary. Therefore, a system based on the Taipei Botanical Garden was introduced by this study.

The forest healing system is an important topic of alternative therapy in recent years. Forest therapy began in 1989 when the psychology professor Kaplan put forward the "Attention Restoration Theory(ART)". Awareness has a positive benefit. To study the influence of Forest therapy, the establishment of a pilot experimental model system in which both environmental factors and type of activity are controlled can greatly reduce the errors caused by the site and the content of the activity. Therefore, a randomized controlled crossover experiment based on the Taipei Botanical Garden was introduced by this study.
