本研究選用國產材紅檜、臺灣扁柏、臺灣杉、杉木、柳杉，透過選用之樹種精油及板材進行氣相層析質譜儀(GC-MS)分析所釋放的芳香氣體揮發物，進行吸聞木材精油及木材板材實驗，並使用腦波儀及電子血壓計量測受試者吸聞前後腦波、血壓及脈搏變化，以評估生理及心理反應。
實驗中受試者在吸聞木材精油及板材後，其 α 波皆呈現上升趨勢，意味著具有放鬆、緩解壓力效果；β 波則呈現下降趨勢，顯示其具有抗焦慮效果；δ 波也呈現上升趨勢，表示具有助眠效果；在血壓及脈搏上呈現下降趨勢，可緩解高血壓，其中以扁柏效果最顯著。
經 GC-MS 分析後，紅檜主要成分樟烯(Camphene，20.37%)；臺灣扁柏主要成分樟烯(Camphene，18.22%)；臺灣杉主要成分 α-雪松烯(di-epi-α-Cedrene，9.91%)；杉木主要成分樟烯(Camphene，31.81%)及柳杉主要成分樟烯(Camphene，36.19%)；而 Camphene 為選用樹種中主要成分，幫助人體抗氧化、抗發炎、抗菌達到物理治療；包括可幫助緩解壓力、放鬆及身心情緒穩定，達到心理治療。
因此國產材可應用於不同室內空間機能配置，促進身心健康，且具有建材開發之潛在發展，達到居家療癒空間之效用。
In this study, (GC-MS) was used to analyze aromatic volatiles released by wood essential oils and boards, and changes in brain waves, blood pressure, and pulse before and after inhalation were measured through sniffing experiments, electroencephalography and electronic sphygmomanometers to evaluate physiological and psychological effects. The results showed that α and δ waves increased while β waves decreased, and blood pressure and pulse rate declined after inhalation, producing relaxing, anti-anxiety, sleep-aiding, and blood pressure-lowering effects, with Taiwanese cypress showing the most significant effect. GC-MS analysis indicated that the main component of each tree species is camphene, which has antioxidant, anti-inflammatory, and antibacterial effects, helping relieve stress and stabilize mood. Therefore, domestic wood has the potential to promote physical and mental well-being and can be applied to interior space design and development of healing building materials.
