FACT OR FALLACY? Guyabano – an end to chemotherapy


             Guyabano fruit is a green, pear-shaped fruit covered with soft spines. Matured guyabano or soursop fruit weighs about 2 to 5 kilograms. It is ovoid and large, up to 18 centimeters long, with thin skin and the soft edible whitish pulp that is fleshy and fibrous and has inedible black seeds. It has also a distinct sweet-sour flavor that tastes like pineapple and strawberry with a tang of sour citrus taste.

The Story:

What would you do if you have just earned yourself the right to retire from government service after more or less 60 years and just relax on your resthouse, only to be told that you are dying of cancer? Seems like heaven disallowed its joyous rays to cast upon you?

Rose Palacio, a post government employee, had developed dermoid cyst, which is malignant, which led to her being diagnosed of cancer last October 2009.

“I was asked by my doctor to get a second opinion but the second opinion confirmed her findings and the second doctor also recommended that I be operated on the soonest possible time if I still wanted to live,” she said. Of course, she was barely alive then, suffering from long bouts of stomach pain and her inability to urinate for several days. She was hospitalized when she was no longer able to bear the pain of cancer seeping through her entire body, but the anxiety coming from the fear of where to get money for her mounting hospital bills made her decide to beg her doctor to release her.

“He said if I don’t get the operation then I was as good as dead but realizing that I had decided not to get the operation for financial and other reasons, he asked me to buy all the guyabano I can find in Bankerohan Public Market,” she said. “Sabi n’ya Rose, bilhin mo lahat ng guyabano na makita mo at inumin mo oras-oras (Rose you buy all the guyabano you can find and drink it every hour).”

                She then drank guyabano shake every hour, even alarming late at night just to continue her hourly dosage. Supposedly, ripe guyabanos which are sweet are to be taken, but due to the scarcity of ripe ones, she drank even the bitter raw guyabanos just to comply with her requirements, even without sugar because sugar contains chemicals that may lessen the potency of the guyabano.

                In less than three days, she was able to urinate and had regular bowel movement.The pain also lessened and while I had but pains regularly before, it was reduced as the days went on, she said. Two weeks later, her colleagues in the media could not believe it when they saw Rose covering one of the press conferences in the city, looking healthier and as if nothing happened. When asked what she did to get rid of her malady, she would gladly utter one word — guyabano.

The Pros:            

Researchers have confirmed that guyabano contains Annonaceous acetogenins or chemicals with very strong anti-tumorous properties. The beauty of these chemicals is that while these are toxic to cells with cancer, it does not affect the healthy cells. One of the reasons why cancer patients like Rose refuse to undergo chemotherapy is because of its adverse effects on healthy cells. With guyabano, only the cancerous cells are affected.  An unreleased report by the US National Cancer Institute in 1976 has included guyabano or Graviola in the list of plants that were found to be effective in killing malignant cancer cells. Research shows that a lot of clinical studies have been made on the anti-cancer properties of guyabano but it has yet to be tested on cancer patients.

The Cons:

                The idea that graviola is an effective cancer fighter evidently stems from research (published in 2008) conducted at the Purdue University’s School of Pharmacy and Pharmaceutical Sciences on the unique substances known as annonaceousacetogenins that have been extracted from the graviola tree. The Purdue investigators found these substances to be potent inhibitors of cancer cells while leaving normal cells alone. They also found the compounds to be effective against drug-resistant cancer cells.

But these studies were conducted in vitro, i.e., conducted on cancer cells in test tubes. These are a long way from clinical trials that determine the efficacy and safety of these compounds in people with cancer. In fact, there were not any human study found on graviola and cancer.

Another possible reason for this might is that, the intake might just be a placebo. The placebo is clearly evident in the famous phrase, “mind over matter”.  It is a simulated or otherwise medically ineffectual treatment for a disease or other medical condition intended to deceive the recipient. Sometimes patients given a placebo treatment will have a perceived or actual improvement in a medical condition, a phenomenon commonly called the placebo effect. That means, an individual given a placebo, in this case, a  guyabano, as an anti-cancer medicine will induce a psychological effect and belief that guyabanos are really effective; deceiving the human brain to allow the human body to surpass sickness and diseases and may have the capacity to develop therapeutic claims and physiological healing.

Conclusion:

Even without due scientific evidence and global acceptance, it wouldn’t be that bad to try taking guyabanos as an anti-cancer fruit. Practically thinking, nothing would even change whether the dosage of guyabano would work-out or not – if drinking the guyabano shake should not compensate the cancer  present, then chemotherapy is the only chance of survival, if the latter choice would cure you of cancer, then even better.
