Science
Mechanism of Action
This oil acts through multifaceted antimicrobial and anti-inflammatory pathways. Its bioactive constituents contribute to improving overall skin texture, making it beneficial for calming fungal conditions, eczema, and psoriasis, and soothing scalp irritations. Specifically, the essential oil derived from the stem can mitigate atopic dermatitis-like skin lesions by suppressing IgE and histamine production, thereby reducing IgE-mediated degranulation. It also exhibits a mast cell stabilizing effect by down-regulating interleukin-4 secretion. A key component, Hinokitiol, provides significant antibacterial and antifungal activity.
