You may have heard about graviola, soursop, guanabana and corrosol and assumed
that all of these were different plants. In fact, they are all one and the same, the Annona muricata which is prevalent in tropical forests across Southeast Asia, Africa and Central
and South America. What you call the plant actually depends on where you live: soursop in English, graviola in Brazil, guanabana in Spanish and corrosol in French.
We prefer to use the term graviola because it is the most commonly used name across much of the world and it certainly sounds more palatable than soursop! However, we do sometimes refer to soursop as just another word for graviola.
Soursop is a well-known plant to the indigenous peoples of Central and South America, and was first discovered by Europeans over 500 years ago. Western scientists have actively studied the graviola tree since the 1970s, and a considerable amount of information is available about the plant.
Graviola is generally cultivated around the world as a food source and the Soursop fruit is popular in much of South East Asia and Latin America.
Both traditionally and contemporarily, Soursop has been sought-out for its many health benefits and is today increasing in popularity as an herbal supplement for cancer treatment, diabetes and as a mild sedative to relieve stress and hypertension. As a point of note, most homeopathic graviola remedies use the Soursop leaf and NOT the Soursop fruit, as this is where the active ingredients can be found.
Graviola proved itself to be a cancer-killing dynamo. The National Cancer Institute performed it's first scientific research in 1976. The results revealed that Graviola’s “leaves and stems were found effective in attacking and destroying malignant cells.” Inexplicably, the results were published in an internal report but never released to the public. Since 1976, Graviola has proven to be an extremely potent cancer killer in 20 independent laboratory tests, but as of now, no double-blind clinical trials.
Graviola fruit powder and leaf powder suggested servings are half a teaspoon (0.5g) 2 to 3 times a day. Graviola powder has many different uses. It can be made as a hot or cold tea. Can be added to any juice or smoothie. Can also be used in cooking and baking.
Pregnant woman and patients with Parkinson's disease should not consume soursop products. Patients undergoing chemotherapy should consult their physician before drinking graviola tea.
