wanted to test this theory and prepared an extract of papaya leaves in water. This aqueous extract was administered in a dose of 25 ml twice daily for five consecutive days to a patient who was infected with dengue fever.
The blood reports (platelets count, white blood cells and neutrophils) showed that papaya leaves exhibited potential activity against dengue fever. The researchers suggest that different parts of the papaya may used as a strong natural candidate against viral diseases.

This all suggests that in the near future, possible new active ingredients against dengue could be harvested from leaves and seeds of the papaya plant.
