Expert on Papaya Leaf Suggests Trials for Ebola

/home/wpcom/public_html/wp-content/blogs.dir/0a6/50714193/files/2014/12/img_1109-0.jpg
Dr Sanath Hettige, long-time researcher on the effects of papaya leaf on Dengue Fever, proposed publicly in the BMJ on October 2014 evidence to support and request a coordinated clinical trial “worth trying” on papaya leaf to combat Ebola fever.

The reasons for his proposal are summarized by the following research evidence: (excerpt from the BMJ 2014;349:g4997)

PAPAYA LEAF EXTRACT FOR EBOLA PATIENTS – WORTH TRYING

Papaya leaf extract is now proven to be effective for dengue fever. (Not merely by increasing the platelet count). The pathology of Ebola virus seems to be similar to that of Dengue fever. Especially when considering the endothelial dysfunction and the hemorrhagic stage. Therefore I strongly feel that Papaya leaf extract will benefit Ebola patients. Researches have shown many beneficial effects of carioca papaya leaf extract on human body which will benefits to fight viral infections. They include:-

1) Stimulation of the hematopoietic system which stimulates Platelet production, White Blood Cell production and Red Blood Cell production (1, 2, 3, 4).
2) In-vitro erythrocyte membrane stabilization properties (5, 6).
3) Stimulates the immune system which enhances the activity against the viral infection (7).
4) Direct anti-viral activity on dengue virus (8).
5) Animal studies have shown that it prevents chemically induced capillary leakage in Mice (9).
6) Preliminary studies conducted by Dr. Sanath Hettige have shown that Carioca papaya leaf extract prevents the drop in serum-Albumin levels in Dengue patients.
Randomize open label case control trial is on going to find out whether Carioca papaya leaf extract can prevent fluid leakage in Dengue fever (10).
7) Many toxicology studies have not shown any significant toxic effects even at higher doses (11).
