Lung histopathology was assessed using microscopic analysis and immunohistochemistry investigation for TNF-α and IL-6. The results showed that the positive control of AgNPs slightly triggered proinflammatory cytokines and created an oxidative stress status in lung tissue. The group IOLE AgNPs treatment significantly restored the normal organization of the control lung tissue. It reduced alveolar and septal congestion, edema, and necrosis compared to the infected lung. Therefore <i>I. oblongifolia</i> as a natural medical plant displayed significant antimalarial and anti-oxidant properties effectively, reducing inflammatory signs and cytokine levels in <i>P. chabaudi</i>-infected lungs and treating the harmful impact of AgNPs in <i>P. chabaudi</i>-infected + <i>I. oblongifolia</i> with AgNPs lung.

Consequently, the study compared the efficacy of <i>I. oblongifolia</i> with that of CQ, revealing that the latter exhibited limited efficiency due to drug resistance and its inability to restore the normal features of its histology.
