We investigated the psychological and antibacterial effects of footbath with Lu essential oil. The participants included 20 women without medical history and received two intervention plans: footbath without any essential oil and footbath using Lu essential oil. Next, questionnaires regarding impressions and mood states were provided for them to answer. In addition, their autonomic nervous system activity was measured, and the aerobic viable of count on the feet was determined. The high-frequency value reflecting the parasympathetic nervous system activity significantly increased after footbath using Lu essential oil. In the questionnaire about the mood states, the subscale scores of tension\u2013anxiety, depression, fatigue, and confusion after intervention were lower than those before intervention regardless of the use of the essential oil. Conversely, the anger\u2013hostility score decreased only in the group using Lu essential oil. Furthermore, the decrease in aerobic viable count after intervention was not significantly different between the two groups. Footbath using Lu essential oil increased the parasympathetic nervous system activity and relieved anger. Taken together, we suggest that footbath using Lu essential oil has a relaxation effect.<\/jats:p>","DOI":"10.3390\/molecules26175128","type":"journal-article","created":{"date-parts":[[2021,8,24]],"date-time":"2021-08-24T22:09:39Z","timestamp":1629842979000},"page":"5128","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Psychological and Antibacterial Effects of Footbath Using the Lindera umbellata Essential Oil"],"prefix":"10.3390","volume":"26","author":[{"given":"Maiko","family":"Kitajima","sequence":"first","affiliation":[{"name":"Department of Nursing Sciences, Hirosaki University Graduate School of Health Sciences, 66-1 Hon-cho, Hirosaki 036-8564, Aomori, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marika","family":"Miura","sequence":"additional","affiliation":[{"name":"Department of Nursing Sciences, Hirosaki University Graduate School of Health Sciences, 66-1 Hon-cho, Hirosaki 036-8564, Aomori, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4729-3432","authenticated-orcid":false,"given":"Naoki","family":"Nanashima","sequence":"additional","affiliation":[{"name":"Department of Bioscience and Laboratory Medicine, Hirosaki University Graduate School of Health Sciences, 66-1 Hon-cho, Hirosaki 036-8564, Aomori, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3428-6719","authenticated-orcid":false,"given":"Toshiko","family":"Tomisawa","sequence":"additional","affiliation":[{"name":"Department of Nursing Sciences, Hirosaki University Graduate School of Health Sciences, 66-1 Hon-cho, Hirosaki 036-8564, Aomori, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shizuka","family":"Takamagi","sequence":"additional","affiliation":[{"name":"Department of Nursing Sciences, Hirosaki University Graduate School of Health Sciences, 66-1 Hon-cho, Hirosaki 036-8564, Aomori, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miyuki","family":"Fujioka","sequence":"additional","affiliation":[{"name":"Department of Bioscience and Laboratory Medicine, Hirosaki University Graduate School of Health Sciences, 66-1 Hon-cho, Hirosaki 036-8564, Aomori, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8653-0069","authenticated-orcid":false,"given":"Naoya","family":"In","sequence":"additional","affiliation":[{"name":"Department of Nursing Sciences, Hirosaki University Graduate School of Health Sciences, 66-1 Hon-cho, Hirosaki 036-8564, Aomori, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomohiro","family":"Osanai","sequence":"additional","affiliation":[{"name":"Department of Nursing Sciences, Hirosaki University Graduate School of Health Sciences, 66-1 Hon-cho, Hirosaki 036-8564, Aomori, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"308","DOI":"10.1002\/ptr.2072","article-title":"Pharmaceutical and therapeutic Potentials of essential oils and their individual volatile constituents: A review","volume":"21","author":"Edris","year":"2007","journal-title":"Phytother.
