pls am carrying out a research on the active ingredient on local plants.
please I need help on three local plants that cures the same disease so that I can compare the most active one among the three.

for example
paw paw leaves-- malaria
lemon grass-malaria
dongoyaro----malaria

note:this is just an example as I don't really know if the following cures the disease.

I look forward to your replies.
