Science
Mechanism of Action
LINDERA UMBELLATA TWIG OIL operates through multiple pathways to benefit the skin. It exhibits robust anti-inflammatory effects by inhibiting the production of key pro-inflammatory cytokines such as nitric oxide, interleukin-6, and tumor necrosis factor-α. This action is mediated by the suppression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression in activated macrophages. Furthermore, it demonstrates broad-spectrum antibacterial activity against both Gram-positive organisms like S. aureus and Gram-negative bacteria such as E. coli. The presence of linalool, a major component, contributes to its relaxing and calming properties, while the oil as a whole provides general antioxidant protection, mitigating cellular damage from free radicals.

Key findings
- 01 Showed effective antibacterial activity against S. aureus, with bacterial growth completely inhibited at concentrations exceeding 100 mg/ml (equivalent to 10%).
- 02 Decreased the growth rate of E. coli, with noticeable effects at 50 mg/ml (equivalent to 5%) and maximum turbidity suppression observed at 800 mg/ml (equivalent to 80%).
- 03 Kuromoji essential oil (KEO) suppressed LPS-induced production of pro-inflammatory cytokines (nitric oxide, IL-6, TNF-α) and inhibited iNOS and COX-2 mRNA and protein levels in RAW 264.7 cells, demonstrating anti-inflammatory potential.
