Graviola Cancer Research
Graviola Cancer Research is unquestionably an encouraging, organic treatment and one of which emphasizes the significance of protecting our remaining rainforest environments. Graviola is a modest, up-right evergreen tree, 5-6 meters high, with significant, glossy, dark green leaves. It generates a sizable, heart-shaped, delicious fruit which is 15-20 centimetres across, is yellow-green colored, and possesses white flesh inside.
It is native to the majority of the warmest exotic areas in South and North America, such as Amazon. The fruit comes within local markets within the tropics, where it is known as guanábana within Spanish-speaking countries and graviola throughout Brazil. The fruit pulp is fantastic for producing beverages as well as sherbets and, although somewhat sour-acid, may be consumed raw.
Tribal and Herbal Medicine Applications
Every part of the tree is utilized throughout natural medicine throughout the tropics, which includes the bark, leaves, roots, fruit, as well as fruit seeds. Various qualities and uses are attributed to the various areas of the tree. Commonly, the fruit along with fruit juice are consumed for worms and parasites, to lessen fevers, to improve mother’s milk following childbirth, and as an astringent with regard to diarrhea and dysentery. The smashed seeds are utilized in opposition to inner and outer parasitic organisms, head lice, as well as worms. The bark, leaves, and roots are regarded as a sedative, antispasmodic, hypotensive, and nervine, and a tea is produced for numerous ailments.
Graviola includes a lengthy, vibrant reputation of use within organic medication in addition to a prolonged documented indigenous use. Throughout the Peruvian Andes, a leaf tea is employed for catarrh (irritation of mucous membranes) and the crushed seed is utilized to eliminate parasitic organisms. In the Peruvian Amazon the bark, roots, along with the leaves are utilized for diabetic issues and as a sedative and antispasmodic. Native tribes in Guyana make use of the leaf and/or bark tea as a sedative and heart tonic.
In the Brazilian Amazon, a leaf tea is utilized for liver issues, and the oil of the leaves and unripe fruit is combined with olive oil and utilized externally for neuralgia, rheumatism, and arthritis pain.
Throughout Jamaica, Haiti, as well as the West Indies, the fruit and/or fruit juice is utilized for fevers, parasites and diarrhea; the bark or leaf is employed as an antispasmodic, sedative, and nervine for heart ailments, coughs, flu, difficult childbirth, asthma, high blood pressure, and parasites.
Graviola Cancer Research: Plant Compounds
Through Graviola cancer research, numerous active substances and chemicals have been discovered within the fruit, as researchers have been researching its qualities since the 1940s. The majority of the exploration on graviola concentrates on a novel group of chemical substances referred to as Annonaceous acetogenins. Graviola generates these natural ingredients throughout its leaf and stem, bark, and fruit seeds.
Three independent research organizations have verified that these chemical substances have substantial antitumorous qualities and selective toxicity in opposition to different types of cancer cells (without doing harm to healthy cells) publishing 8 scientific studies on their conclusions. The majority of the acetogenins have exhibited discerning toxicity to tumor cells at suprisingly low dosages-as little as 1 part per million. Four scientific studies had been released in 1998, which further identify the chemical substances and acetogenins within graviola, which are displaying the strongest anticancerous, antitumorous, and antiviral components. In a 1997 medical study, novel alkaloids present in graviola fruit demonstrated antidepressive effects in animals.

Annonaceous acetogenins are exclusively identified in the Annonaceae family (to which graviola belongs). These chemical substances generally have been recorded with antitumorous, antiparasitic, insecticidal, and antimicrobial activities. Mode of action scientific studies in 3 independent laboratories recently established that these acetogenins are exceptional inhibitors of enzyme procedures, which are exclusively identified within the membranes of cancerous tumor cells.
For this reason, they are toxic to cancer cells, however have no toxicity to healthy cells. Purdue University, in West Lafayette, Indiana, has carried out significant amounts of Graviola cancer research on the acetogenins, much of which, has been financed by The National Cancer Institute and/or the National Institute of Health (NIH).
To this point, Purdue University and/or its staff have submitted at least 9 U.S. and/or international patents on their work around the antitumorous and insecticidal components and uses of these acetogenins.
In 1997, Purdue University released details with encouraging information that a number of of the Annonaceous acetogenins were not only are successful in eliminating tumors that have confirmed resistant against anti-cancer agents, but additionally appear to have a unique affinity for such resistant cells. In a number of interviews after this information was released, the head pharmacologist in Purdue’s analysis described exactly how this worked.
As he describes it, cancer cells that survive chemotherapy can establish a level of resistance to the agent initially utilized in addition to additional, even unrelated, medicines. This occurrence is known as multi-drug resistance (MDR).
One of the primary methods that cancer cells develop opposition to chemotherapy drugs is through producing an intercellular pump, which is effective at pushing anticancer agents out of the cell before they are able to kill it. Typically, merely about 2 % of the cancer cells in any given individual may develop this pump, however those are the 2 % that can ultimately grow and expand to produce multi-drug-resistant tumors.
Purdue researchers documented that the acetogenins preferentially wiped out multi-drug-resistant cancer cells by obstructing the exchange of ATP, the main supply of cellular energy into them. A tumor cell requires energy to expand and replicate, and a good deal more to operate its pump and discharge attacking agents.
Through suppressing energy to the cell , it can no longer operate its pump. Once acetogenins obstruct ATP towards the tumor cell over time, the cell will no longer have sufficient energy to function preserving procedures and it perishes. Typical cells hardly ever develop this type of pump; consequently, they do not demand substantial portions of energy to operate a pump and, typically, are not negatively impacted by ATP inhibitors. Purdue researchers documented that fourteen various acetogenins examined to date illustrate effective ATP obstructing qualities (including numerous discovered exclusively within graviola). Additionally, they documented that thirteen of these fourteen acetogenins examined were more effective in opposition to MDR breast cancer cells than the 3 typical medications (adriamycin, vincristine, and vinblastine) they used as controls.
The Annonaceous acetogenins identified in graviola so far consist of: annocatalin, annohexocin, annomonicin, annomontacin, annomuricatin A & B, annomuricin A thru E, annomutacin, annonacin, annonacinone, annopentocin A thru C, cis-annonacin, cis-corossolone, cohibin A thru D, corepoxylone, coronin, corossolin, corossolone, donhexocin, epomuricenin A & B, gigantetrocin, gigantetrocin A & B, gigantetrocinone, gigantetronenin, goniothalamicin, iso-annonacin, javoricin, montanacin, montecristin, muracin A thru G, muricapentocin, muricatalicin, muricatalin, muri-catenol, muricatetrocin A & B muricatin D, muricatocin A thru C muricin H, muricin I, muricoreacin, murihexocin 3, murihexocin A thru C, murihexol, murisolin, robustocin, rolliniastatin 1 & 2, saba-delin, solamin, uvariamicin I & IV, xylomaticin
Graviola Cancer Research
Within an 1976 plant screening program by the National Cancer Institute, the leaves along with the stem demonstrated active toxicity in opposition to cancer cells. Scientists have been following up on these discoveries ever since.
To date, particular acetogenins in the fruit and leaves have been documented to be uniquely toxic in vitro to these kinds of tumor 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.
Scientists in Taiwan documented in 2003 that the primary acetogenin, annonacin, was extremely toxic to ovarian, cervical, breast, bladder as well as skin cancer cell lines at surprisingly low dosages declaring annonacin is an encouraging anti-cancer agent and deserving of additional animal experiments and, we’d desire, clinical trials.
An intriguing in vivo study had been released in March of 2002 by researchers in Japan, who have been researching numerous acetogenins present in several species of plants. They inoculated mice with lung cancer cells.
One third acquired nothing (the control group), one third acquired the chemotherapy drug adriamycin, and one third acquired the primary graviola acetogenin, annonacin (at a dosage of 10 mg/kg). At the conclusion of 2 weeks, 5 of the 6 in the untreated control group remained as alive and lung tumor sizes were then assessed. The adriamycin group showed a 54.6% decrease in tumor mass over the control group, however 50% of the animals passed away from poisoning (3 of 6). The mice acquiring annonacin were all still alive, and the tumors had been limited by 57.9%, somewhat better than adriamycin and without toxicity. This led the scientists to review; “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.”
Present Practical Functions
Cancer investigation is continuing on these essential Annona plants and plant chemicals, as a number of pharmaceutical drug companies and universities continue to research, analyze, patent, and attempt to synthesize these chemical compounds into new chemotherapeutic medicines. In fact, graviola appears to be pursuing the similar path as another popular cancer medication – Taxol.
From the moment scientists first identified an antitumorous effect in the bark of the pacific yew tree and a novel chemical known as taxol was identified in its bark – it required 30 years of investigation by several pharmaceutical drug companies, universities, and government agencies prior to the first FDA-approved Taxol drug was sold to a cancer patient (which was dependent on the natural taxol chemical they discovered in the tree bark). With graviola, it’s taken scientists nearly ten years to effectively synthesize (chemically replicate) the primary antitumorous chemical, annonacin.
These acetogenin chemicals have a distinctive waxy center and additional distinctive molecular energy qualities, which thwarted previous efforts, and at least one significant pharmaceutical drug company gave up during this process (regardless of understanding how active the natural chemical was in opposition to cancers).
Since researchers possess the capability to replicate this chemical and many other active acetogenins within the laboratory, the following action is to modify the chemical only enough (without sacrificing any of the antitumorous actions in the process) to become a novel chemical substance, which in turn could be copyrighted and changed into a brand new patented cancer medication. (Naturally-occurring plant chemicals are not able to be patented.)
To date, scientists appear to be thwarted again, each and every moment they alter the chemical enough to be patentable, they lose a great deal of the antitumorous actions. Much like the improvement of taxol, this could take federal government agenies such as the National Cancer Institute and the National Institute of Health to advance and release full-scale human cancer research on the synthesized unpatentable natural plant chemical (which will permit any pharmaceutical drug company to create a cancer medication making use of the research as occurred with taxol) to have the ability to make this encouraging therapy accessible to cancer patients in due time.
Meanwhile, numerous cancer patients and health professionals aren’t holding out. They are incorporating the natural leaf and stem of graviola (with more than forty recorded naturally-occurring acetogenins including annonacin) as a complementary treatment to their cancer practices. All things considered, graviola includes a lengthy background of safe use as a herbal treatment for various other conditions for quite some time, and research signifies that the antitumorous acetogenins are uniquely toxic to only cancer cells and not healthy cells and in small quantities.
While research verifies that these types of antitumorous acetogenins also exist in high quantities within the fruit seeds and roots, different alkaloid chemicals within the seeds and roots have demostrated some initial in vitro neurotoxic results. Scientists have recommended that these alkaloids may be associated with atypical Parkinson’s disease in countries in which the seeds are utilized as a common herbal parasite treatment. Consequently, making use of the seeds and root of graviola isn’t suggested at this time.
The therapuetic dosage of graviola leaf, (which provides equally as high of an amount of acetogenins as the root and nearly as much as the seed) is documented to be 2-3 grams taken three or four times a day. The products (capsules and tinctures) have become extensively obtainable in the U.S. marketplace, and now supplied under a number of different manufacturer’s labels in health food stores. As one of graviola’s mechanisms of action is to diminish ATP energy to cancer cells, mixing it along with other supplements and natural products, which improve or boost cellular ATP may lessen the effect of graviola. The primary supplement which increases ATP is a very common antioxidant called Coenzyme Q10 and for this purpose, it must be avoided whenever consuming graviola.
Graviola is unquestionably an encouraging, organic treatment and one that again emphasizes the significance of protecting our remaining rainforest environments. Perhaps, if enough individuals believe that the potential remedy for cancer genuinely is locked away within a rainforest plant, we will consider the required process needed to safeguard our remaining tropical rain forests from devastation. One investigator researching graviola abbreviated this concept gracefully: “At the time of preparation of this current review, over 350 Annonaceous acetogenins have been isolated from 37 species. Our preliminary efforts reveal that about 50%, of over 80 Annonaceous species screened, are considerably bioactive and therefore are deserving of fractionation; thus, these types of compounds can be anticipated to continue to develop at an rapid rate in the future, provided that monetary assistance for such research initiatives can be discovered. With the decline of the world’s tropical rain forests, such work is persuasive before the great chemical diversity, included throughout these vulnerable species, is lost.”
