The HA was retrieved from the PubChem database, while antiplasmodial target proteins from different stages of the <jats:italic>Plasmodium falciparum<\/jats:italic> life cycle were collated from the Protein Databank (PDB). Molecular Docking and Visualization were conducted between the compound and target proteins using AutoVina PyRx software and Biovia Discovery Studio, respectively. Also, the AdmetLab 3.0 algorithm was used to predict the absorption, Distribution, Metabolism, Excretion, and Toxicity (ADMET) profiles of HA. Based on a 4-day suppressive test, the antiplasmodial activity against the <jats:italic>Plasmodium berghei ANKA<\/jats:italic> strain in mice was evaluated. Furthermore, subacute toxicity and micronucleus assays were used for further toxicity assessment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The molecular docking analysis indicates multi-stage, multi-target potentials of HA with favourable ligand-receptor complexes across the four <jats:italic>Plasmodium falciparum<\/jats:italic> stages. Meanwhile, the mice administered with 100\u00a0mg\/kg, 50\u00a0mg\/kg, and 10\u00a0mg\/kg of HA demonstrated considerable chemosuppression in a dose-dependent manner of 89.74%, 83.80%, and 71.58% percentage chemosuppression, respectively, at <jats:italic>p<\/jats:italic> &amp;lt; 0.05. The ADMET prediction, histopathological tests, and micronucleus assays show that HA is safer at a lower dose.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study showed that n-Hexadecanoic acid is a potential drug candidate for malaria.
