-The acaricidal activity of C.obtusa leaves against Dermatophagoides farinae and Dermatophagoides pteronyssinus likely results from [[https://en.wikipedia.org/wiki/Thujaplicin|β-thujaplicin]]. "On the basis of a 24 h LC50 value, acaricidal activity against D. farinae was more pronounced with β-thujaplicin (72.2 mg/m2) than benzyl benzoate (89.9 mg/m2) and DEET (377 mg/m2). Acaricidal activity against D. pteronyssinus was more pronounced in β-thujaplicin (62.1 mg/m2) than benzyl benzoate (72.4 mg/m2) and DEET (193 mg/m2)." \\
+Hinokitiol (thujaplicin), was not found in the neutral wood oil of C.obtusa. Yoshixol (4,4-dimethyl-6-methylene-2-cyclohexen-1-one) was regarded as major constituent the neutral wood oil. Yoshixol showed strong antibiotic effects on MRSA, Escherichia coli, Mycobacterium chelonei, Pseudomonas aureginosa and Candida albicans. \\

+"Aromatic volatile substances (phytoncides) were produced by vaporizing Chamaecyparis obtusa (hinoki cypress) stem oil with a humidifier in the hotel room during the night stay. Blood samples were taken on the last day and urine samples were analysed every day during the stay.  NK activity, the percentages of NK and T cells, and granulysin, perforin, granzyme A/B-expressing lymphocytes in blood, and the concentrations of adrenaline and noradrenaline in urine were measured. Similar control measurements were made before the stay on a normal working day. The concentrations of phytoncides in the hotel room air were measured. Phytoncide exposure significantly increased NK activity and the percentages of NK, perforin, granulysin, and granzyme A/B-expressing cells, and significantly decreased the percentage of T cells, and the concentrations of adrenaline and noradrenaline in urine." \\
