Carvacrol is a monoterpene phenol with oral activity[1]. Carvacrol has antioxidant, antibacterial, antifungal, anticancer, anti-inflammatory, hepatoprotective, antispasmodic, and vasodilatory properties[2]. Carvacrol is usually used in research related to cancer and inflammation[3]. Carvacrol is also used as a flavoring agent and preservative in food at low concentrations, as well as a fragrance component in cosmetic formulas[4].
In vitro, treatment of MCF-7 breast cancer cells with Carvacrol (0-250µM; 24 or 48h) significantly reduced cell viability, induced cell cycle arrest at the G0/G1 phase, and promoted cell apoptosis[5].
In vivo, Carvacrol (20-80mg/kg/day; p.o.; 6 days) significantly reduced the levels of pro-inflammatory cytokines TNF-α and IL-6, malondialdehyde (MDA), nitric oxide (NO), and arginase activity in a rat sepsis model induced by LPS in a dose-dependent manner[6]. Carvacrol (30mg/kg/day; intraperitoneal injection from postoperative day 1 to day 9) significantly prolonged graft survival, reduced inflammatory cell infiltration in skin allografts, and decreased the expression of pro-inflammatory cytokines such as IL-6, TNF-α, and IL-17 in a mice skin allograft model[7].
