What's your opinion on graviola as an alternative cancer treatment?

Not Effective: Graviola or soursop is a fruit grown in rain forests in s.America, africa & se asia. The fruit contains substances known as annonaceous acetogenins which may be able to kill certain cancer cells in a test tube (according to a perdue u study). No studies in humans have been done so there's no evidence that it can work to kill cancer in your body. It can also cause parkinson's like symptoms.
