**3. Biological and medicinal usefulness of RPO**

Studies indicate that RPO has beneficial effects on arterial thrombosis and hypertension associated with oxidative stress [11, 12] and is also protective against the consequences of ischemia/reperfusion injury [13, 14]. More so, Aboua et al. [15] showed that RPO could possibly inhibit apoptosis in rat sperm, while its role in reducing oxidative stress in HIV/AIDS and tuberculosis patients has also been reported [16]. Besides, RPO has been reported to be useful in wound healing [17]. Moreover, as palm oil is very rich in carotenes, it is also found useful for preventing and treating vitamin A deficiency [18]. Therefore, due to its antioxidant effect, RPO is recommended as a supplement to the diet of pregnant women. RPO also possesses potentials in preventing high blood pressure and breast cancer [19].
