Key findings
- 01 In vitro/ex vivo studies at 0.0005-0.005% concentration effectively suppressed fMLP-induced oxidative stress, reduced pro-inflammatory cytokines (TNF-α, IL-8), and enhanced plasma's antioxidant capacity.
- 02 An in vitro study at 0.0032% demonstrated increased FN1 gene expression in human dermal fibroblasts, indicating potential for wound healing.
