Graviola (Annona muricata)

Studies show soursop to be a powerful cancer fighter

Soursop is an evergreen tropical tree in the Annonaceae family. While its leaves are used for making tea and its delicious fruits — botanically related to the cherimoya — are widely used for preparing smoothies, fruit juice drinks, candies, sorbets, and ice cream flavoring, the Annona muricata is also known as "cancer killer" — e.g. in Malaysia —, where different parts of the trea are widely used to treat cancer and tumors.

Other folk medicine applications include parasitic infestations, diabetes, diseases of the liver, skin, heart, flu-like infections, rheumatism, neuralgia, arthritis, fever, diarrhea, dysentery, pellagra, hypertension, insomnia, fungal infestations, and use as a relaxant.[1]

Modern research has since found scientific evidence supporting many of these traditional areas of application.

The fruits, bark, leaves and roots of A. muricata are rich in flavonoids (which inter alia lower the risk of cardiovascular disease), isoquinoline alkaloids (which boast sedative, psychotropic, and analgesic properties) and especially annonaceous acetogenins[1], more than a 100 of which have already been isolated from the leaves, bark, seeds, roots and fruits of A. Muricata.[2]

Annonaceous acetogenins are uniquely found in the Annona species (Annonaceae family) and owing to their potential antitumor activity, are considered one of the most promising classes of natural products.[3]


Annonaceous acetogenins from A. muricata kill malignant cells of twelve different types of cancer including colon, breast, prostate, lung, liver, pancreatic, ovarian as well as lymphoma cells.[4]


In animal models* and laboratory testing, graviola fruit extract was shown to inhibit the growth of human breast cancer cells while having no effect on normal human breast epithelial cells.[5]

An in-vitro study (test-tube experiment) tested a liquid-graviola fruit extract on human breast cancer cells. The extract was found to inhibit cell growth and provoke cell cycle arrest and apoptosis.[6]

In another study, breast cancer was artificially induced in rats which were divided into four different groups. While all developed pronounced histopathological signs in their breast and ovarial tissues, these mostly disappeared in the groups that received graviola fruit. The researchers mainly attributed these positive effects to graviola‘s antioxidant, anti-inflammatory, and antiproliferative components.[7]

* Healing Cancer Naturally does not support animal experimentation since it harms both animals and humans.


Three studies published between 2014 and 2017 reported the discovery of new anti-proliferative annonaceous acetogenins from graviola fruit. All these heretofore unknown acetogenins demonstrated (sometimes pronounced) antiproliferative action against human prostate cancer cells.[8]

Since typically prostate cancer will be discovered at an early stage, preventive measures (chemoprevention) are particularly important. Judging by observations made on mice, the NADPH oxidase enzyme complex is directly associated with prostate cancer progression and hence a signalling molecule of use in prostate cancer prevention.

So researchers looked at the effect of graviola pulp extract on NADPH oxidase in prostate cancer cells. Result: the extract exerted a very strong inhibitory effect upon the activity of the enzyme complex. In nonmalignant prostate cells, graviola neither inhibited NADPH oxidase nor had it any other detrimental impact. The researchers concluded that graviola fruit extracts would lend themselves for preventing prostate tumor progression.[9]


In search of ever new anticancer drugs, modern cancer researchers have discovered nanotech. They are experimenting inter alia with silver nanoparticles (between 1 nm and 100 nm in size) as carriers for delivering various payloads such as small molecules to specific target tissues (here: tumor cells) to be selectively released (which helps of course to reduce chemotherapy's toxic effects on the entire body).

A study from 2019 compared the efficiency (cytotoxic activities) of silver nanoparticles carrying Annona muricata (fruit and leaf extract) upon cervical and prostate adenocarcinoma cells with that of 5-Fluorouracil (a cytotoxic chemotherapy medication) and was able to show potential anticancer activity.[10]

A similar study[11] showed the silver nanoparticles carrying Annona muricata fruit extract to have significant antiproliferative effect upon both cell lines while selectively sparing normal cells. The fruit-carrying nanoparticles were considerably more effective than both the "first-line therapy" 5-Fluoruracil and the nanoparticles carrying Annona-muricata leaf extracts. Consequently, the researchers particularly recommend Annona-muricata fruit for use in the development of novel and better anticancer drugs.


A Korean study investigated the impact of extracts from graviola leaves, fruits and seeds upon human astroglioma cells, finding significant cytotoxic effects on cell proliferation in a dose-dependent manner.[12]


A 2021 study investigated the effect of a graviola fruit pulp extract upon human colon cancer cell lines, comparing it with that of the chemotherapy medication Paclitaxel (Taxol). The extract altered multiple metabolic pathways playing a part in cancer cell proliferation and thus can be considered a promising anticancer agent due to its selective inhibition of cancer's energy metabolism.[13]


Diabetes and high blood pressure (particularly soursop fruit[14]), pain relief and inflammation[15], [16], mucositis (gastrointestinal inflammation[17], envenomation[18], and malaria.[19]


Typically, fruits contain little to no lactic acid but the soursop fruit contains an incredible 13.56 ± 2.00 percent.[20] Perhaps this furnishes another puzzle piece why soursop fruits can help with cancer (see research results of Johannes Kuhl, MD, PhD re the significance of lactic acid).
