This fruit is called soursop or guanabana and has been proven to be 10,000 times more effective than chemotherapy at reversing the affects of cancer. However it does this very differently to chemo though, instead of killing all the cells surrounding the cancer cells often resulting in hair loss, fatigue, nausea, vomiting, anemia, infection, easy bruising/bleeding plus many more! On the contrary "the compound extracted from the Graviola tree selectivelyhunts down and kills only cancer cells. It does not harm healthy cells!"
Why haven't you heard of this amazing fruit?! Well long story short a large company years ago spent millions to find a cure for cancer. However in order for them to have made their money back and further profit from their finding they needed to create a synthetic duplicate of the compound found in the soursop as they could not pattern something natural. Unfortunately for them they were unable to do this so they left it all and didn't publish their findings.
Not only the fruit, but the leaves as well. I have a cousin who is a nurse and she transports truck load of soursop leaves and gives to her willing patients.
