Soursop scientific skepticism. MORINGASOP Moringa Sop ~E.G.Plott

Does soursop cure cancer?


Dear Eric PlottPalmTrees Farm,

 Is with great pleasure and admiration that I address these few lines to you in appreciation as to the manner in which you received us at your humble place of business on a very difficult Sunday for us after having traveled 320 miles one way, and I say gladly!  Because only a person like you (Eric Plott) with such moral values, integrity, knowledge and a profound heart could have only been there to welcome us that Sunday with a personal call from your 800 number.

After you had learned the day before regarding our family tragedy involving our two and half year old grandnephew who was diagnosed with brain cancer. Upon showing us the website information on Soursop plants & Moringa you had separated for us very thoughtfully, and instructed us as to the care of such along with a Moringa Miracle Tree, and a (Soursop) tea plant. You had the kindest gesture in presenting us with a Miracle Box which initially changed our lives forever!

This was done in a most humble way two persons could have only done so.  

 Only true friends like you would have done something so commendable.

Well, let me say my dear friends that with God's help,  Moringa and constant Soursop leaves tea bags (You) handmade (from) your nursery produced plants and given to Andrew he has began using his left arm and is not dragging his left leg anymore. 

The best news is that the tumor has shrunk dramatically according to the last MRI. Our stomach issues have improved 80%+ from the Moringa and we no longer have been taking Omeprazole 40 mg. or Zantac 150 for the acid reflux or gastritis!

I am convinced now that this small but giant nursery is not only Plott
's Blessed Nursery but also God's Pharmacy!

In closing the plants are doing wonderful as instructed by you. 

Eric Plott,  God has put his blessed hands in you to have the knowledge in plants and there benefits, hope you continue to used it as you have been for the benefit of all. Proudly accept this letter and display it in your business with the utmost pride and honor. I remain always your friend.

I was linked a website about the effect soursop has in fighting cancer. The website heavily implies that soursop is an effective cancer treatment similar to chemo.

soursop source

Chemotherapy is a widely known form of cancer treatment and is effective at destroying cancer cells however, as commonly known it may come with numerous side effects. One of those side effects that is more than likely inevitable is that of hair loss. This is because while chemo is destroying those harmful cancer cells in the body it is also causing harm to the normal healthy cells. As prior mentioned, this does not occur with soursop. The soursop kills damaged cells, and ONLY the damaged cells leaving the body immune to most of the side effects associated with chemotherapy. Some may also go as far as saying that soursop is "10,000 times stronger than chemo", but there are no cold hard facts behind this claim. What is factual and proven through scientific study is that the soursop, with its annonaceous acetogenins is more effective in targeting the cells that cancer patients want to target ie the cancer cells.

Major claims:

  • Soursop is an effective cancer treatment.
  • Soursop prevents cancer from occuring in the first place.
  • Soursop targets cancer cells leaving regular cells unharmed.

Does the research show that these are credible claims, since the page is saying there's been much research published on this, since the 70's?

I tend to be skeptical of sites that have lots of misspelled words especially if they are found through out the FAQ. While I am not apposed to a miricle cure-all, I the more things it claims to treat the more I think I will stay with my current snake oil... which treats only soberness and does so fairly effectively :) –  Chad Dec 12 '11 at 20:35
@Chad: I would like to add a word of caution towards anyone who says he has the "cure for cancer". Cancer is not ONE disease, is a spectrum, and an enormously large one, of diseases with different etiology, where many different molecular mechanisms are in place. Even within the same type of cancer (say, breast cancer), there is often not ONE cure that fits all, as they are all different. –  nico Dec 13 '11 at 3:56

A search in the Pubmed database for "soursop cancer" (which is automatically expanded to ("annona"[MeSH Terms] OR "annona"[All Fields] OR "soursop"[All Fields]) AND ("neoplasms"[MeSH Terms] OR "neoplasms"[All Fields] OR "cancer"[All Fields]), so it will not only show exact matches) shows 43 results, though none of those are trials in humans.

One of those results is an article titled "Complementary therapies, herbs, and other OTC agents.", in the abstract it states

Graviola demonstrated anticancer effects in vitro, but has not been studied in humans. Despite the lack of human data, many websites promote graviola to cancer patients based on traditional use and on the in vitro studies. Caution is required as there is no evidence of safety or efficacy.

There are several in vitro studies, but no human studies seem to have been performed. The result of such studies can't just be transferred to humans, you have to actually perform some clinical studies. The in vitro studies show that it has some potential as an anti-cancer drug, but that is a far shot from being proven effective in actually being safe and effective against cancer in humans.

There is also some data that the annonacin in graviola can cause an atypical Parkinson disease (12,345).

With the possible danger of causing atypical Parkinson and no evidence that soursop is actually effective against cancer in humans, I would strongly recommend to avoid it.

Straight from the wikipedia article (emphasis my own):

Research carried out in the Caribbean has suggested a connection between consumption of soursop and atypical forms of Parkinson's disease due to the very high concentration of annonacin.[3][4][5][6]

According to Cancer Research UK, Annona muricata is an active principle in an unlicensed herbal remedy marketed under the brand name Triamazon.[7] Triamazon is not licensed for medicinal use and the sale of the product resulted in a conviction on four counts of selling unlicensed medical products, and other charges, for a vendor in the United Kingdom.[8]

So not only is it the main ingredient in an unapproved cancer treatment, it's been linked to Parkinson's disease. [Ref]

That doesn't mean it doesn't have potential. Research is just incomplete. From

In laboratory studies, graviola [a.k.a. Soursop] extracts can kill some types of liver and breast cancer cells that are resistant to particular chemotherapy drugs. But there haven’t be
