Four spices prevent mice from contracting Salmonella enterica serovar Typhimurium. Exp Ther Med. 2019 Oct;18(4):2956-2964 Authors: Chang CH, Fu JH, Su CH, Yin MC, Hsu YM Abstract Ligustrum lucidum Ait (LL), Lysimachia christinae Hance (LC), Mentha piperita Linn (MP), and Cinnamomum cassia Presl (CC) are common spices used in Asia. The present study investigated the anti-Salmonella effects of the four spices using aqueous extracts. The amount of phenolic acids and flavonoids in each spice aqueous extract was determined as indicators of purity. Mice were pretreated with LL, LC, MP or CC aqueous extract for 7 days. Following infection with Salmonella enterica serovar Typhimurium strain ST21 (ST21), the aqueous extract of each spice was subsequently administered for 4 days. ST21 infected mice had lower body weight compared with the control group. The administration of spice aqueous extracts significantly increased body weight following infection. ST21 infection increased the fecal ST21 counts compared with the control group; however, following spice aqueous extract treatments, ST21 counts significantly decreased. The spice treatments also significantly reduced ST21 count in blood and the organs. Notably, ST21 infection increased interferon (IFN)-γ and interleukin (IL)-6 levels in serum whilst spice treatments reduced these cytokines. In the spleen, spice treatment significantly lowered IFN-γ, IL-6, IL-1β, and tumor necrosis factor (TN...
