This study is the first to describe the anti-protozoal properties of Tongkat Ali against Blastocystis sp.
isolates. Ethyl acetate fraction of Tongkat Ali demonstrated the highest anti-protozoal activity against Blastocystis sp.
isolates and showed a sizeable reduction in the cell count which was comparable with MTZ. Tongkat Ali also
demonstrated a more uniformed sensitivity across subtypes in comparison to the allopathic drugs.
