Papaya Leaf: Don’t Boil it. Brew it.

In a new study that investigated the effect of aboriginal methods using papaya leaf for medicinal effects, the researchers found that the traditional decoctions (boiling the leaves) had LESS effect on cancer cells than the fresh juice from the leaves. This research result is not surprising, as the enzyme papain in the leaf is most effective at 150-160 degrees F. 

The researchers also called their alternative boiling method “brewing”…as in “brewing” tea. 

Tea enthusiasts would not connect to this definition as “brewing” tea is a delicate act of boiling water, letting it cool to the proper temperature, (typically 150-160 F) then pouring over the tea. 

Related to its (papaya leaf tea) effect on cancer, I would encourage the scientists to test again a true, “classically brewed” papaya leaf against the papaya juice to find its effect on this set of cancer cells in the lab.

Again, it is glorious to see strong research indicating the selective effect of papaya leaf on SCC25 cancer cells. Exciting research. Thank you to the team in Australia!!

In this research where a petroleum extract of papaya leaf was compared to two common antibiotics, Perflacine and Cefuroxime on bacterial organisms S Aureus, E-Coli, and P aeruginosa, papaya leaf was found to be more powerful.

Nine Dengue Patients Observed Recovered With Papaya Leaf

A test of the effect of papaya leaf on nine patients with Dengue Fever was published in India last Spring:

“In the present study we found the therapeutic potential of papaya leaf extract (PLE) in curing dengue infection by increasing platelet and WBC counts respectively. Ultrasonographic findings, blood reports, statistical analysis and patient’s recovery from dengue infection further supported the culinary effect of papaya leaf extract (PLE) in dengue patients. The nontoxic nature of PLE also supports its use as natural herbal remedy for dengue infection. An earlier study categorized Carica papaya leaf as non toxic (LD50 >15g per Kg body weight) (Kardono et al., 2003).”

Ayurvedic Practitioner Dr Valerian Mendonca: Papaya Leaves for Chikungunya

2016/01/img_1959.png

“…Herbal medicine in India has been saving lives for thousands of years. Ayurveda is probably as old as the Indus Valley Civilization dating back to 3000 BC. All four Vedas especially the Rig Veda carry references to diseases and their cures through herbs and roots.

The ancient art of Ayurveda was systematically killed by the colonialists when they took over the country. It was suppressed by the British. The East India Company banned and shut down all Ayurvedic colleges in 1833. When Ayurveda re-emerged for almost 100 years, herbal remedies were dismissed as “the poor man’s medicine” practiced in rural areas where western medicine was too expensive or not available. The irony was the country folk were healthier than the urban class.

The Portuguese in Goa actually did shut down Ayurvedic practitioners. The Vaidyas of Hindu Pharmacy were the only Ayurvedic dispensers allowed to practice after one of them saved the life of a Viceroy’s wife.

Only now more and more patients are realising that allopathy or Western Medicine is not just expensive, but has hidden side effects that cause more problems than the original ailment itself.

When the Chikungunya outbreak happened a couple of years ago, The Times of India Mumbai edition carried an article on the effectiveness of the papaya leaf juice cure to completely eliminate the crippling joint pains that kicked in after the fever ended. My brother read the article and was so desperate to try anything to get back to his active life that he experimented with the papaya cure. It worked the same day. He had another two tablespoons the next day and was 100 percent fit.”

Papaya Leaf Determined To Be Safe. Again.

Scientists continue to study papaya leaf to be assured of its safety. It has been shown as “Hepatoprotective” (safe for the liver) Orhan, D.D.; Orhan, N.; Ergun, E.; Ergun, F. Hepatoprotective effect of Vitis vinifera L. leaves on carbon tetrachloride-induced acute liver damage in rats. J. Ethnopharmacol. 2007, 112, 145–151.

A study in 2011 tested the toxicity of papaya leaf
Halim, S.; Abdullah, N.R.; Afzan, A.; Rashid, B.A.A.; Jantan, I.; Ismail, Z. Study of acute toxicity
of Carica papaya leaf extract in Sprague Dawley rats. J. Med. Plants Res. 2011, 5, 1867–1872

And in 2012 another study related to the safety of papaya leaf in malaysia:

“…analysis revealed that the leaf extract of C. papaya cultivar ‘Sekaki’ contains considerable amounts of carpaine, malic acid, quinic acid, manghaslin and clitorin, minor quantities of various malic acid derivatives, nicotiflorin, rutin and unidentified unknown constituents. These complex mixtures did not produce treatment related changes in body weight, food intake, water level, hematological parameters and serum biochemistry in Sprague Dawley rats after oral sub-acute exposure for 28 days.”
