Scientists published papaya leaf tea as invention to combat cancer

Filed in 2005 by Nam Dang and Chikao Morimoto to the US Patent Office, the portion of the application below offers a view from the scientists as to the way to brew and take the tea for effect on more than ten types of cancer. 

The indication from the application looks like it is “preferable” to take one half to three cups per day of papaya leaf tea, approximately, for one to three months to combat the listed cancers.

…”The present invention’s brew/extract components, prepared from, for example, a papaya leaf, or fractionated components thereof, are effective in the prevention or treatment of stomach cancer, lung cancer, pancreatic cancer, liver cancer, colon cancer, uterine cancer, ovarian cancer, neuroblastoma or other solid cancers, or lymphoma, leukemia or other blood cancers. In a preferred embodiment, treatment is administered to those suffering from a disease. In another embodiment, treatment is administered as prophylaxis. The dose of the brew/extract components or fractionated components thereof to be administered will depend on the dosage form, symptoms of the subject, type of cancer or the like. However, for example, when the brew/extract is taken, it is normally preferable to take an amount of 100 ml to 750 ml per day, every day for between one month and three months. When the fractionated components are taken, it is preferable to take an amount of 10 ml to 200 ml per day, every day for between one month and three months.”

The scientists, along with Noriko Otsuki, also published in the Journal of Ethnopharmocology the following study in 2010, “Aqueous extract of Carica papaya leaves exhibits anti-tumor activity and immunomodulatory effects” which revealed in detail their science behind the tea.

This article is not intended to prescribe the tea, only to publish information related that is available by academics who study papaya leaf.

Set of Minerals in Papaya Leaf May Explain Medicinal Value

Scientists show a strong mineral set in the papaya leaf. The manganese specifically helps the body absorb enzymes. The powerful protease enzymes papain and chymopapain in the papaya leaf (which are considered cancer and inflammation fighters) may find a path to absorption through the manganese.

“…It has now been found that certain proteolytic enzymes are activated in the presence of ions of calcium, magnesium, manganese, cobalt or combinations thereof… Preferred for use as single activators are calcium and magnesium.”

The study on CP leaves done herewith has shown very rich minerals composition in green, yellow and brown leaves, which were collected from the plain as well as hill area of Northern India and CP leaves, can be seen as a potential source of useful drug, food & dietary supplement. The brown leaf can be used as anti-anaemic agent. It possesses immune-stimulants with anti-oxidant property. In the recent case study report, CP leaves extract controls dengue infection, has opens new gateway and raised eyebrows of many scientists. On the other hand, the presence of important anti-oxidants & vitamins may suppress various free radicals species induced during the viral infection. Particularly, the mineral composition may balance the mineral deficiency promoted by the virus and strengthen the immune cells against the dengue virus. The usefulness of these nine minerals obtained, like Ca, Mg, Mn, Na, K, Fe, Zn, Cu and Cr, which are found in rich quantity in CP leaves. The minerals are the elements that originate in the Earth and cannot be made by living organisms. Plants obtain minerals from the soil, and most of the minerals in our diets come directly from plants or indirectly from animal sources.

…Manganese (Mn) plays an important role in a number of physiologic processes as a constituent of multiple enzymes and an activator of other enzymes. A number of manganese- activated enzymes play important roles in the metabolism of carbohydrates, amino acids and cholesterol17.

…Manganese activates several enzyme systems and supports the utilization of vitamin C, E, choline, and other B-vitamins.

In Conclusion,
Therefore, papaya leaves due to its potent therapeutic properties can be formulated in herbal formulations as a medicine/dietary supplement and may be marketed as a nutraceutical product and as well as drug in curing the several diseases like Dengue fever, malaria etc.
