Keys: Values for the packed cell volume (PCV) and body weight (BW) are presented as mean (M) ± standard error of the mean (SEM); n = 5 (number of mice/group in a single experiment); D0: day 0 (day-of-extract-inoculation); D4 = day 4 (the fifth day pos-extract-inoculation; mg/kg/day: 1mg of extract per one kilogram of mice for one day; NC: negative control; T-80 = Tween-80 (NC for chloroform extract); dH₂O: distilled water (NC for aqueous and methanol extract); CQ: chloroquine phosphate; *: significant compared with that of NC; ^a: significant difference between D0 and D4. **the first value is for the comparison between D0 and D4, the second is with the NC
