Olive Leaf Extract may improve the clinical status and decrease the length of hospitalization in patients with Covid-19.
Over 140 patients completed this randomized, triple blinded clinical study. Using block randomization, eligible participants were assigned to 1 of 3 groups. Intervention Group A received 250mg of Olive Leaf Extract every 12 hours. Intervention Group B received a 500 mg dosage of Olive Leaf Extract every 12 hours. The control group received a placebo every 12 hours. The study lasted 5 days.
Outcomes which were assessed by an infectious disease specialist included vital signs like body temperature, mean blood pressure, respiratory rate, pulse rate and peripheral O2 saturation. These outcomes were taken at the onset of the study and daily until the end of the study. Intervention Group A’s vital signs were significantly lower at the end of the study and oxygen saturation was higher when compared to the control group. Intervention Group B also saw significant reductions in vital signs with significantly higher oxygen saturation rates when compared with the control group. There was not a significant difference between Intervention Group A and B in terms of study outcomes.
Previous studies have shown Olive Leaf extract to exhibit antioxidant, antibacterial, antifungal and antiviral properties. Antiviral properties of Olive Leaf Extract have been observed to be effective against HIV, HPV, HCV, HBV, HSV and influenza virus A.
Researchers are calling for further studies with larger sample groups.
