Extracts of Graviola are effective against some viruses, bacteria, and parasites in test tubes. Laboratory studies have also shown Graviola to be effective against some types of cancer cells. It contains chemicals called acetogenins, which are thought to be the active ingredient. However, there are no human trials testing Graviola against cancer.

Brief History

Graviola has a long, rich history of use in herbal medicine as well as an extended recorded indigenous use. In the Peruvian Andes, a leaf tea is used for catarrh, and the crushed seed is used to kill parasites In the Peruvian Amazon the bark roots and leaves are used for diabetes and as a sedative and antispasmodic. Indigenous tribes in Guyana use a leaf and/or bark tea of Graviola as a sedative and heart tonic. In the Brazilian Amazon, a leaf tea is used for liver problems, and the oil of the leaves and unripe fruit is mixed with olive oil and used externally for neuralgia, rheumatism and arthritis pain. In Jamaica, Haiti and the West Indies, the fruit and/or fruit juice is used for fevers, parasites, as a lactagogue, and diarrhea; and the bark or leaves are used as an antispasmodic, sedative, and nervine for heart conditions, coughs, grippe, difficult childbirth, asthma, asthenia, hypertension and parasites.

Primary Uses


In a 1976 plant screening program by the National Cancer Institute, Graviola leaves, and stem showed active toxicity against cancer cells. Thus far, specific acetogenins in graviola and/or extracts of Graviola have been reported to be selectively toxic in vitro to these types of tumour cells: lung carcinoma cell lines; human breast solid tumor lines; prostate adenocarcinoma; pancreatic carcinoma cell lines; colon adenocarcinoma cell lines; liver cancer cell lines; human lymphoma cell lines; and multi-drug resistant human breast adenocarcinoma.

Researchers in Taiwan reported in 2003 that the main graviola acetogenin, annonacin, was highly toxic to ovarian, cervical, breast, bladder and skin cancer cell lines at very low dosages saying; “. . . Annonacin is a promising anti-cancer agent and worthy of further animal studies and, we would hope clinical trials.”

An interesting in vivo study was published in March of 2002 by researchers in Japan, who were studying various acetogenins found in several species of plants. They inoculated mice with lung cancer cells. One-third received nothing (the control group), one-third received the chemotherapy drug adriamycin, and one-third received the main graviola acetogenin, annonacin (at a dosage of 10 mg/kg). At the end of two weeks, five of the six in the untreated control group were still alive, and lung tumour sizes were then measured. The adriamycin group showed a 54.6% reduction of tumour mass over the control group—but 50% of the animals had died from toxicity (three of six). The mice receiving annonacin were all still alive, and the tumours were inhibited by 57.9%—slightly better than adriamycin—and without toxicity. This led the researchers to summarise; “This suggested that annonacin was less toxic in mice. On considering the antitumor activity and toxicity, annonacin might be used as a lead to develop a potential anticancer agent.”
