Protease Enzyme Therapy for Cancer and Papaya Leaf

Scientists continue to work to define the reason why proteases like the ones in papaya leaf (papain and chymopapain) have shown to slow the growth of tumors.

“…we have discovered that proenzyme therapy, mandated first by John Beard nearly one hundred years ago, shows remarkable selective effects that result in growth inhibition of tumor cells with metastatic potential.”

John Beard, a Scottish doctor, proved the effect of trypsin (a protease taken from a young cow) on halting the growth of tumors in humans by injecting part of the Pancreas of the young cow straight into human tumors.

Papain has been shown to be more powerful of a protease than trypsin.

They meticulously proved in the lab the effect of papaya leaf tea on various cancer cell lines. Details were published in the
Journal of Ethnopharmacology 127 (2010) 760–767

Aqueous extract of Carica papaya leaves exhibits anti-tumor activity and immunomodulatory effects

This study among others have shown that papaya leaf tea should be considered as a new herbal treatment for cancer.

Other studies have contributed to this conclusion, even absent large clinical trials; that the tea is non-toxic even in large doses*, and that papaya leaf tea has existed in ethno-medicine (traditional medicine) all over the world as a treatment for cancer, dengue fever, malaria, etc.

Large clinical trials have shown the effect of proteases on cancer. Papaya leaf tea contains two of the most powerful proteases found in the world; papain and chymopapain. Papain has shown to be most active between 150-160 degrees F, a perfect tea temperature.

The tea is commercially available for retail purchase at a reasonable price.

Now we need our cancer healing communities to spread this word.
This is the goal of the Julia Ruffin Project: To promote, research, and grow papaya leaf tea.
