Graviola, also known as soursop or Brazilian paw paw, is the fruit of the Annona muricata evergreen tree. Native to tropical areas of Central and South America, it serves a dietary supplement used to treat many conditions.
Graviola is hailed as a wonder herb. Its popularity as a natural remedy for viruses, pain relief, and even some types of cancer is gaining ground. Keep reading to learn if research backs the hype.
Research suggests that graviola has a number of health benefits:
It has antioxidant properties
Antioxidants keep cells healthy by hunting disease-causing free radicals in the body and destroying them.
According to a 2014 study, graviola extract has many compounds with antioxidant abilities.
Antioxidants help people stay healthy overall. More research is needed to determine if graviola’s antioxidants prevent specific diseases.
It has anti-inflammatory properties
According to a
Still, researchers cautioned more study is needed to determine if graviola is safe for humans. It is unclear if it would have the same pain-relieving effects.
It may help lower blood sugar
The results of a
In addition, despite the rats being fed less food and water, they didn’t lose weight. Researchers believe this may be the result of better glucose control.
It may help lower blood pressure
A 2012 study on rats found graviola helped reduce blood pressure without increasing heart rate. According to researchers, the herb’s hypotensive abilities are due to “peripheral mechanisms involving antagonism of Ca²⁺ [calcium ions].”
It may help prevent ulcers
Ulcers are painful sores that develop in the stomach lining, esophagus, or small intestine.
According to a
It may help treat herpes
Herpes is a viral infection caused by the herpes simplex virus. It may appear on the genitals or mouth.
Graviola is considered an alternative treatment for herpes, but the supporting evidence is still coming in. A 2012 study showed antiherpes activity with graviola in the laboratory.
According to a
It may be anticancerous
There is some evidence graviola may battle some types of cancer. According to
It also increased T cells. T cells are lymphocytes in the body that kill cancer cells and other damaged cells.
Still, researchers caution graviola alone is not enough to eradicate pancreatic tumors. It should not be used as a primary treatment. Studies are ongoing to evaluate the efficacy of graviola as an adjuvant therapy for pancreatic cancer.
Graviola is available in capsule or extract forms. There is not enough research to determine a safe, standardized dose.
In general, manufacturers recommend taking 500 to 1,500 milligrams via capsule daily or 1 to 4 milliliters of extract daily.
These dosages have not been approved by the United States Food and Drug Administration (FDA). The FDA does not monitor production, quality, or purity of supplements and herbs.
Some health practitioners recommend avoiding graviola due to the risk of neurological side effects.
Graviola may cause nerve damage and movement problems, especially with long-term use. It may also cause serious neuropathy that leads to Parkinson-like symptoms, such as tremors or stiff muscles. If someone has Parkinson’s disease, graviola may make their symptoms worse.
Graviola may be toxic to the kidneys or liver with repeated use. People should not use graviola if they have liver or kidney problems.
Those considering using graviola should also talk to their doctor before use if they:
- have high blood pressure or take blood pressure medications
- have diabetes
- are pregnant
- are breastfeeding
Although graviola has been shown to be effective against some conditions in animal studies, there are few human studies on graviola.
Users have offered anecdotal evidence, but more scientific study on humans is needed before researchers can say that graviola is effective in treating any condition.
If someone is interested in adding graviola to their routine, they should talk to their doctor. They can advise them on ther individual risks and potential benefits, as well as answer any questions they may have.
