What is Graviola?

Graviola is a large tropical tree with a rich history of traditional use for conditions like cancer, parasitic infection, insomnia, and dysentery. Modern use remains very similar, mainly focusing on tension headaches and muscle aches, insomnia, diabetes, cancer, hypertension, and parasitic infection.

Although the entire plant has been used as medicine by various traditional medical systems, the most common form the plant is available in today is as a leaf extract, and raw leaves intended for tea.

Graviola is gaining in popularity outside worldwide as a general health supplement, blood sugar regulator, and anticancer agent. As a result, it's getting easier to find the herb as time goes on. It is likely this tea will become a staple in Western herbal medicine in the coming years.

How Is Graviola Used?

Graviola is mainly used as an adjunctive treatment for cancer, especially leukemia and other haematological cancers, as well as prostate, colon, and breast cancers.

Graviola is also popular as an anti-diabetic herb, and can be used to reduce hypertension, especially in combination with diabetes or metabolic syndrome.

Graviola is a potent anti-parasitic, useful for a wide range of different parasitic species, including worms, protozoa, and bacterial parasites.

 

Traditional Uses of Graviola

+ South America

Graviola originated from South America and/or the Carribean. All parts of the plant were used as medicine for a wide range of conditions.

The most common use of the plant appears to involve cancer treatment and parasitic infection.

The darkest leaves on the plants were used primarily as a sedative or antispasmodic. They were used to treat insomnia, arthritic pains, colic, dysentery, muscle aches, headaches, and diabetes. The leaves were often placed inside a pillow or bedsheets to improve sleep.

In Brazil, the leaves were made into a tea for treating various liver conditions. The oil of the leaves and unripe fruits were used topically for treating neuralgia, and arthritis.

In Peru, the leaves were used to treat excess catarrh, and the bark and root were used for treating diabetes, insomnia, and muscle aches.

In Guyana, the leaves were used as a heart tonic.

+ Southeast Asia

In Southeast Asia, graviola was an important treatment for malaria. It was made into candies, ice cream, and syrups for treating malaria and other parasites.

Botanical Information

Graviola is a large tree, growing to a height of 10m. It requires high humidity, warm weather, and high annual rainfall in order to thrive. It produces large, edible fruits with an acidic taste (hence the common name soursop).

There are over 130 different genera in the Annonaceae family, and around 2300 different species. The Annona genus itself has about 70 different species. Annona muricata is the most commonly grown worldwide.

 

Phytochemistry

There are over 100 annonaceous acetogenins in the plant, which are considered to be the primary active constituents of the plant. Structurally these chemicals are derivatives of long chain (C35 or C37) fatty acids. These compounds are cytotoxic against tumour cell lines, and molluscicidal.

Graviola is also rich in alkaloids, saponins, terpenoids, flavonoids, coumarins, lactones, anthraquinones, tannins, cardiac glycosides, phenols, and phytosterols.

+ Complete Phytochemical Makeup

The leaves contain annomuricins A and B, gigantetrocin A, annonacin-10-one, muricatetrocins A and B, annonacin, goniothalamicin, muricatocins A and B, annonacin A, (2,4-trans)-isoannonacin, (2,4-cis)-isoannonacin, annomuricin C, muricatocin C, gigantetronenin, annomutacin, (2,4-trans)-10R-annonacin-A-one, (2,4-cis)-10R-annonacin-A-one, annopentocins A, B and C, cis- and trans-annomuricinD-ones, annomuricine, muricapentocin, muricoreacin and murihexocin C and annocatacin A and B.

Graviola contains reticulin, coreximine, coclarine and anomurine.

Graviola contains β-caryophyllene, δ-cadinene, epi-α-cadinol and α-cadinol.

 

Clinical Applications Of Graviola:

Graviola is useful for parasitic infection, including protozoan, and helminth parasites. It's used as a mild sedative and antispasmodic, and can be very useful for gastrointestinal inflammation and dysbiotic conditions.

Graviola is also a popular treatment for diabetes by slowing lipid per-oxidation, and restoring islet beta-cells in the pancreas.

It's commonly used as an adjunctive treatment of cancer, especially haematological cancers and colon cancer.

 

Cautions:

Graviola has been reported to increase symptoms of Parkinson's Disease.

Caution advised in combination with other hypoglycaemic drugs due to potential additive effect.

+ Contraindications

  • May exacerbate Parkinson's Disease symptoms (Acetogenin content)
  • Caution advised in combination with other hypoglycemic drugs due to potential additive effect.
