Han X, Parker TL Cogent Biology, 2017 ABSTRACT: Melaleuca (Melaleuca alternifolia) essential oil (MEO), commonly known as tea tree oil, is popularly used in skincare products. In the current study, we investigated the biological activity of a commercially available MEO (with terpinen-4-ol as the major active component) in pre-inflamed human dermal fibroblasts, which were designed… Read more »
Lemongrass (Cymbopogon flexuosus) essential oil demonstrated anti-inflammatory effect in pre-inflamed human dermal fibroblasts
Han X, Parker TL Biochimie Open, 2017 ABSTRACT: Lemongrass (Cymbopogon flexuosus) essential oil (LEO), which has citral as its main component, has exhibited anti-inflammatory effect in both animal and human cells. In this study, we evaluated the anti-inflammatory activity of a commercially available LEO in pre-inflamed human dermal fibroblasts. We first studied the impact of… Read more »
Anti-inflammatory activity of Juniper (Juniperus communis) berry essential oil in human dermal fibroblasts
Han X, Parker TL Cogent Medicine, 2017 ABSTRACT: Although juniper (Juniperus communis) berry essential oil (JEO) has been used in skin care products, research on its biological activity in human skin cells is scarce. In the current study, we explored the biological activity of JEO (with alpha-pinene as the major active component) in pre-inflamed human dermal… Read more »
Biological activities of frankincense essential oil in human dermal fibroblasts
Han X, Rodriguez D, Parker TL Biochimie Open, 2017 ABSTRACT: Although frankincense essential oil (FREO) has become increasingly popular in skin care, research on its biological activities in human skin cells is scarce, if not completely absent. In the current study, we explored the biological activities of FREO in pre-inflamed human dermal fibroblasts by analyzing… Read more »
Cardamom (Elettaria cardamomum) essential oil significantly inhibits vascular cell adhesion molecule 1 and impacts genome-wide gene expression in human dermal fibroblasts
Han X, Parker TL Cogent Medicine, 2017 ABSTRACT: Cardamom (Elettaria cardamomum) essential oil (CEO) is popular in skin care, although no studies have reported its biological activity in human skin cells. We studied its effect on 17 protein biomarkers closely related to inflammation, immune responses, and tissue remodeling using a dermal fibroblast cell culture system… Read more »
Arborvitae (Thuja plicata) essential oil significantly inhibited critical inflammation- and tissue remodeling-related proteins and genes in human dermal fibroblasts
Han X, Parker TL Biochimie Open, 2017 ABSTRACT: Arborvitae (Thuja plicata) essential oil (AEO) is becoming increasingly popular in skincare, although its biological activity in human skin cells has not been investigated. Therefore, we sought to study AEO’s effect on 17 important protein biomarkers that are closely related to inflammation and tissue remodeling by using… Read more »

Han X, Gibson J, Eggett DL, Parker TL Phytotherapy Research, 2017 ABSTRACT: Mental health issues have been increasingly recognized as public health problems globally. Their burden is projected to increase over the next several decades. Additional therapies for mental problems are in urgent need worldwide due to the limitations and costs of existing healthcare approaches…. Read more »
Anti-inflammatory activity of clove (Eugenia caryophyllata) essential oil in human dermal fibroblasts
Han X, Parker TL Pharmaceutical Biology, 2017 CONTEXT: Clove (Eugenia caryophyllata Thunb. [Myrtaceae]) essential oil (CEO) has been shown to possess antimicrobial, antifungal, antiviral, antioxidant, anti-inflammatory and anticancer properties. However, few studies have focused on its topical use. OBJECTIVE: We investigated the biological activity of a commercially available CEO in a human skin disease model…. Read more »
Antiinflammatory Activity of Cinnamon (Cinnamomum zeylanicum) Bark Essential Oil in a Human Skin Disease Model
Han X, Parker TL Phytotherapy Research, 2017 ABSTRACT: The effect of cinnamon (Cinnamomum zeylanicum) bark essential oil (CBEO) on human skin cells has not been elucidated. Therefore, we investigated the activity of a commercially available CBEO in a validated human dermal fibroblast system, a model of chronic inflammation and fibrosis. We first evaluated the impact… Read more »
Aromatherapy with two essential oils from Satureja genre and mindfulness meditation to reduce anxiety in humans
Soto-Vásquez MR, Alvarado-García PA Journal of Traditional and Complementary Medicine, 2016 ABSTRACT: The goal of this study was to verify whether association of aromatherapy with essential oils of Satureja brevicalyx or Satureja boliviana and mindfulness meditation can reduce anxiety levels in humans. A randomized experimental trial was carried out with 108 participants who were divided… Read more »
