Guyabano and Cancer
The “Journal of Medicinal Chemistry” published a study regarding the ability of the guyabano extract’s 14 structurally diverse Annonaceous acetogenins in inhibiting the growth of adriamycin-resistant human mammary adenocarcinoma cells. This cell line was found to be a multidrug resistant cancer cell.
After testing the guyabano extract, researchers found that some of its acetogenins were more potent than Adriamycin and may have some chemotherapeutic potential, particularly when it comes to tumors which are multidrug resistant.
Twenty more laboratory test in different laboratories worldwide were conducted and came out with unanimous results:
Guyabano tree extracts is an effective remedy against the growth of malignant cells in 12 different cancer types. These include the deadliest forms of cancer such as breast, lung, colon, pancreatic, and prostate cancer.
The Purdue University in Indiana, United States and the Catholic University of South Korea found that guyabano tree extracts, while successfully fighting the dangerous cells, acted in a way without harming the normal cells unlike with chemotherapy that destroys all the cells that multiply. These findings were published in the Journal of Natural Products.
