Centella asiatica extract
Centella asiatica extract is an orally active herbal extract. Centella asiatica extract scavenges free radicals, increases stratum corneum hydration, improves epidermal barrier function, and reduces skin redness and skin pH. Centella asiatica extract inhibits pro-inflammatory cytokines, suppresses p38 MAPK phosphorylation, reduces mast cell infiltration, and decreases the expression of TNF-α, IL-4, IL-5, IL-6, IL-17, CXCL9, iNOS and COX-2. Centella asiatica extract upregulates the expression of BDNF and downregulates the expression of VGLUT1, and exhibits neuroprotective effects under hypoxic conditions. Centella asiatica extract inhibits pro-inflammatory M1 macrophage polarization and prevents adipose tissue senescence. Centella asiatica extract can be used in studies related to hypoxia-induced neurological dysfunction, atopic dermatitis, and obesity-induced insulin resistance.

In Vitro
Centella asiatica extract (100-500 µg/mL; 1 h pre-incubation; 24 h stimulation with IFN-γ/TNF-α) dose-dependently reduces the expression levels of pro-inflammatory proteins COX-2 and IL-6 in IFN-γ/TNF-α-stimulated human keratinocyte HaCaT cells[3].
Centella asiatica extract (200 μg/mL; pre-incubated for 30 min prior to 24 h LPS stimulation) alters the mRNA expression of Il10 in RAW264.7 mouse macrophages stimulated with low glucose and LPS (HY-D1056)[4].
Centella asiatica extract (200 μg/mL; 30 min pre-incubation prior to 24 h LPS stimulation) inhibits the polarization of high glucose plus LPS-stimulated RAW264.7 mouse macrophages toward pro-inflammatory M1 macrophages by reducing the mRNA expression of Ccl2, Il6, Il1b and Tnf[4].
Centella asiatica extract (CA) (10-1000 µg/mL; 24 h) shows no cytotoxicity against HaCaT human keratinocytes at concentrations up to 500 µg/mL, while cytotoxicity is observed starting from the concentration of 600 µg/mL[3].
Centella asiatica extract (100-500 µg/mL) has detectable polyphenol and flavonoid contents, and exhibits concentration-dependent ABTS and DPPH free radical scavenging activity[3].
