Previous studies have been conducted on domestic materials as a single extract. Research on complex mixtures for maximizing plant characteristics by individual extraction and potential interference with effects is insufficient. Therefore, this study confirmed the GC-MSD according to the extraction of essential oils for Agastache rugosa O. Kuntze(AR), Pinus densiflora Sieb. et Zuccarini(PD), Curcuma longa, Curcuma domestica(CC), Zingiber officinale Roscoe(ZR), Foeniculum vulgare Miller(FV), and Citrus medica L. var. sarcodactylis Swingle(CS). The cytotoxicity, antioxidant, and anti-inflammatory properties of the blending oil were confirmed to confirm its potential as a cosmetic material. As a result of analyzing GC-MSD aroma components, the main components were estragole of AR, à-Pinene for PD, Zingiberene for CC and ZR, Anethole from FV, and D-Limonene for CS. At a concentration of 100 uL/mL with no confirmed cytotoxicity, NO production was inhibited by 70.62%, DPPH radical scavenging activity was 64.03%, and ABTS radical scavenging activity was 89.55%. Through this, blended essential oil suggests the possibility of useful application as a raw material with antioxidant and anti-inflammatory effects in the cosmetic and food industries.

Exposure to stress can lead to sympathetic hyperactivity, which include a systemic disease with lesions in a broad spectrum of organs and a psychiatric condition. The purpose aimed to evaluate the effect of the korea ginger essential oil on stress hormone and brain tissue response in chronic mild stress-induced rats model of sympathetic hyperactivity. Evaluation method carried out cytotoxicity assessment and component analysis, what observe the effects based on serum biomarker and histopathological analysis of brain tissue. As this time, the korea ginger essential oil was treatment at doses of 100 nl/㎖ for 2 weeks after make a chronic mild stress-induced rats model of sympathetic hyperactivity. As a result, the korea ginger essential oil was not toxic at less than 100 nl/㎖, contents of 6-gingerol was 345 ppm. Compared to the control rats, the korea ginger essential oil treatments significantly reduced the serum concentrations of stress hormone (i.e., ACTH, corticosterone, melatonin). Furthermore, The korea ginger essential oil treatments effectively preserved the TH-immune response was occasionally interrupted in the ventral tegmental area (VTA) and the substantia nigra pars compacta (SNpc). The results indicate that the korea ginger essential oil improved sympathetic hyperactivity. Thus, the korea ginger may be a novel material of aroma oils for the management of sympathetic hyperactivity.
