GRAVIOLA, an immune system booster

While there has been a relatively large amount of laboratory research into the potential of graviola for cancer, many of the other benefits listed below are based on anecdotal and traditional use. Scientific research into the therapeutic benefits of graviola is slim and the information given below is not meant to replace medical opinion.


Much of the recent literature related to graviola has been inspired by recent research into its ability to fight cancer. The Graviola fruit is rich in Acetogenins, which are unique to this plant family. Acetogenins appear to have anti-tumor effects in animal studies.

According to its advocates, graviola extract has been effective against several types of cancer including breast and liver cancer cells though up to now there has been no human research to confirm preliminary studies. (1)

However, laboratory and animal tests have shown a lot of early promise and seem to support its traditional use in the treatment of cancer. Research into the anti-cancer potential of graviola has demonstrated several potentially worthwhile findings. (2) (3)

It must be noted that no trials have ever been conducted on humans and the FDA have not approved its use as a cancer treatment. The best known and most comprehensive studies were carried out by the Purdue University’s School of Pharmacy and Pharmaceutical Sciences and these claims that you can find quite easily with a Google search can be summarized as follows.

It has the ability to target and destroy malignant cancer cells in 12 different types of cancer.
Certain of its compounds were many times more powerful in slowing cancer cell growth than the commonly used chemotherapy drug; Adriamycin.
Graviola extract is selective. It only kills cancer cells and leaves healthy cells unharmed.
More clinical research is certainly necessary to confirm these claims and we can only hope that it will happen in the future.



Graviola has been used for centuries in South America to regulate blood sugar levels in diabetic patients and there is some preliminary modern research that suggests it might well be effective. Certain ingredients in graviola which include phytochemicals might be able to prevent spikes in blood glucose and help to regulate glucose levels.

In one study published in 2008, diabetic rats given graviola for a two week period demonstrated near normal blood sugar levels by the end of the trial without being treated with any other diabetes medication. (4)

Another study showed that diabetic rats fed with graviola also exhibited higher antioxidant levels in the blood as well as healthier livers and a reduced level of unhealthy blood fats. (5.


We all know the importance of a healthy immune system and graviola is said be able to boost the immune system and help to keep illness at bay. Those with a weak immune system might benefit from graviola.



Graviola has antiviral and anti-parasitic properties and has been traditionally used to promote digestive health. Graviola might be used to treat constipation, diarrhea and promote regular bowel movements. Graviola fruit is also eaten traditionally to eradicate intestinal worms and other parasites.


Graviola has antioxidant properties which gives it a number of potential regenerative applications. It can help prevent and repair cell damage and reverse some of the telltale signs of aging such as wrinkles and other skin blemishes.


I retain a healthy dose of skepticism over this claim but there is some anecdotal evidence that suggests graviola can help boost energy levels and fight fatigue.


Although there are plenty investigations and testimonials of this effective product, we always recommend to see a naturopath and/or doctor before taking any product.
