Science
Mechanism of Action
This extract combats oxidative stress by effectively scavenging DPPH and hydroxyl radicals and reducing intracellular reactive oxygen species (ROS). Its anti-inflammatory prowess stems from inhibiting nitric oxide (NO) production, alongside downregulating pro-inflammatory markers such as inducible nitric oxide synthase (iNOS), TNF-α, IL-6, IL-8, MMP1, MCP, and COX-2, including the modulation of NF-κB pathways. For anti-aging, it targets cellular senescence by decreasing β-galactosidase activity and p21 mRNA expression, thereby contributing to cellular longevity.
