VERA FILES FACT CHECK: FB post tungkol sa dahon ng papaya bilang 'lunas' sa dengue nangangailangan ng konteksto
Ang isang online post ng isang netizen na nagrerekomenda ng katas ng dahon ng papaya ay hindi…
A netizen’s month-old online post endorsing papaya leaf juice paints an incomplete picture of its effectivity as a “cure” for dengue.
The Facebook (FB) post, already shared over 183,000 times, continues to circulate as the country faces a nationwide dengue epidemic declared by the Department of Health (DOH) on Aug. 6.
As the number of dengue cases nationwide rose, FB page Kapitans WORLD published on July 8 instructions for juicing papaya leaves, claiming its extract is an “effective treatment” for the disease.
The page, which has published posts about other homemade herbal remedies and “health benefits” of certain foods, gave instructions for extracting the juice by crushing papaya leaves, and prescribed people with dengue to drink a spoon of papaya leaf extract, a spoon of sugar or honey, and a glass of water, thrice a day. It claimed that “dengue will disappear” after two days of drinking the juice.
Kapitans WORLD questioned why the DOH was not educating the public about the supposed cure:
“BAKIT AYAW ITURO NANG DOH NA ANG MABISANG GAMOT SA DENGUE AY ANG KATAS SA DAHON NANG PAPAYA. . . . .ang katas na makuha sa dahon nang papaya ay may taglay na maibalik ang tamang platelets sa katawan natin. . . .
(Why doesn’t the DOH teach people that the effective remedy for dengue is the juice from papaya leaves. . . . . the juice extracted from the papaya leaf can restore normal platelet counts in our body. . . .).”

The page also provided links to an instructional video it posted July 10 on its YouTube channel, also named Kapitans WORLD. It bore the title “The most effective cures for dengue fever” and showed a man demonstrating how to make the concoction using a blender. The footage has been viewed over 8,000 times.
The effectiveness of papaya leaf extract as treatment for dengue is still being evaluated. However, initial studies show the juice indeed has the potential to raise platelet levels in dengue patients.
People with the dengue virus can have decreased platelet counts and platelet dysfunction as the disease progresses, according to 2007 World Health Organization (WHO) guidelines on the disease and a DOH primer.
The Philippine Institute of Traditional and Alternative Health Care (PITAHC), an attached office of the DOH leading research and promotion of traditional medicine, recognized local and foreign records and studies that found papaya leaves to have a positive effect on dengue patients.
In an email to VERA Files, PITAHC said the use of papaya leaves as treatment has been “anecdotally recorded” in the country and provided a link to the Philippine Knowledge Digital Library on Health (PKDLH) -- a national database of traditional medicines “gathered from work of researchers and scholars.” It showed that papaya leaves were being used as a treatment in two focus groups and a community, but the database did not elaborate further.
Meanwhile, PITAHC also took note of studies abroad recorded in the Encyclopedia of Common Medicinal Plants in the Philippines Volume I that found promise in the use of papaya leaves as a treatment for dengue. They were:
However, PITAHC also stressed that large-scale clinical trials still need to be conducted to determine the treatment’s efficacy. It cited a 2016 study in India, published in the International Journal of Applied and Basic Medical Research, which said:
“[Carica] papaya leaf extract can be considered as a potential candidate for increase in platelet count in patients of dengue; however, there is need of high-quality evidence in the form of large clinical trials before a decision related to the use of such extract is made.”

Apart from papaya leaves, tawa-tawa leaves have also been the subjects of research on herbal treatments for dengue. Tawa-tawa is recorded in the PKDLH and Encyclopedia of Common Medicinal Plants of the Philippines, but the latter noted that clinical evidence supporting its efficacy is lacking.
