Kinetics of parasitaemia with or without administration of test samples. The above figure indicates the average group parasitaemia of Coptis rhizome (CR) and Orengedokuto (OGT) compared with negative control (DW) and positive control (CQ). On day 0, all mice were injected 1 × 104Plasmodium yoelii 17X strain intraperitoneally. Two hrs post-challenge, two tested drugs, negative and positive control were administered orally. On day 3 (72 post-challenge) parasitaemia was determined. The x-axis is days after parasite infection while the y-axis shows the percentage of iRBCs
