Yes, even I have read the report. We know that fresh papaya, rich in vitamins and minerals, is very good for the digestive system. But recently researchers have announced about its having properties that can cure the fatal dengue. According to the Ayurveda researchers at the National Institute for Ayurvedic Drug Development, two enzymes namely chymopapin and papin in the raw papaya leaf can fight viral infections. It also helps revive the white blood cells and the platelet counts (gradual decrease/destruction of which is the reason of many people suffering and dying of dengue). The juice, prepared from fresh papaya leaves, avoiding the veins (of the leaves) and then grinding the green, pulpy part to make a paste, indeed is very bitter in taste. Patients can mix it with other fruit juice. Physicians advice that 20-25 ml/four to five teaspoons of it twice a day, continuing for at least a week is enough for dengue patient.
I would also like to inform you that fresh papaya leaf extract is proved to have anti-malarial and anti-cancer properties. In some parts of the globe it has been used as a strong preventive to fight malaria. It's said that some American and Japanese physicians/researchers had discovered the useful enzymes in papaya leaf extract having cancer fighting properties (preventing cervix/ breast/liver/lung/pancreatic cancers). Significantly, as it has not been proved during tests examining the toxic effects in papaya leaves, so consumption of it may be said to have no side effects. We really need more research/study on it.
