Design outcomes

Primary

Measure	Time frame
Phase 1. The effects of the presence and absence of essential plant oils and the effects of different types of essential plant oils will be conducted twice with one week interval between each subject. The total number of subjects will be 50 since 5 different plant essential oils will be administered to 10 subjects, and the total number of sessions will be doubled with and without plant essential oils to 100 sessions. Phase 2 The Uchida-Kraepelin test will be used to determine the effect of the presence or absence of mild stress. The presence or absence of the Uchida-Kraepelin test will be added. One subject will be treated twice, one week apart. The total number of subjects will be 50 and the total number of treatments will be 200. Phase 3 The effects of daily treatments will be examined. The Uchida-Kraepelin test will be used to determine the effect of the presence or absence of mild stress. The presence or absence of the Uchida-Kraepelin test will be added. One subject will be treated on consecutive days. The total number of subjects will be 50 and the total number of treatments will be 200.	—
