Variability in experimental models, dosing regimens, and treatment timing limits reproducibility and the definition of safe therapeutic windows

Peripheral blood mononuclear cells (PBMC) and leukemic THP-1 cell viability can be affected by aqueous root extracts of WS (0.050.4 mg/ml), which can also increase oxidant scavenging and caspase [99, 100] activities while decreasing levels of tumor necrosis factor-alpha (TNF-), interleukin (IL)10, and glutathione (GSH) [112]

The first is by stimulating fibroblasts and promoting the formation of new blood vessels to help hair follicles receive the necessary nutrients for growth
