Fig. 3From: Induction of programmed cell death in Trypanosoma cruzi by Lippia alba essential oils and their major and synergistic terpenes (citral, limonene and caryophyllene oxide)Pharmacological interaction isobolograms among major terpenes of the Citral and Carvone chemotype L. alba essential oils: a limonene with caryophyllene oxide; b limonene with carvone; c limonene with citral; and d limonene with Benznidazole (BNZ). The interaction tests were performed on Epimastigotes, Trypomastigotes and Amastigotes of T. cruzi and Vero cells. Dotted lines correspond to an additive effect; points below, on, and above line indicate a synergistic, additive, and antagonistic effect, respectivelyBack to article page
