Researchers from the University of Colorado Cancer Center report that the more aggressive the cancer cells are, the more effective the grape extract works at targeting and stopping the growth. Grape seed extract is amazing in that it attacks the cancer cells but leaves the healthy cells untouched. This is a departure from conventional cancer treatments that destroy all of the cells in an attempt to stop the spread of cancer.

Actually, the power of grape seed extract seems quite remarkable in this research, which was published in the journal Cancer Letters. Molly Derry, a doctoral candidate in the lab of Rajesh Agarwal, PhD, and investigator at the CU Cancer Center and her team saw that while doses of chemotherapy only increase with more severe cancer cases, such as a stage IV instead of stage II, the amount of grape seed extract required actually decreased.

Derry explained:

“It required less than half the concentration of GSE to suppress cell growth and kill 50 percent of stage IV cells than it did to achieve similar results in the stage II cells.”

“We’ve known for quite a while that the bioactive compounds in grape seed extract selectively target many types of cancer cells. This study shows that many of the same mutations that allow colorectal cancer cells to metastasize and survive traditional therapies make them especially sensitive to treatment with GSE.”

Amazing Grapes

One of many berry types, grapes were introduced to America over 300 years ago. There are over 8,000 grape varieties with the main types being American and European. With only 100 calories per cup, grapes are a great source of vitamins K and C and are loaded with antioxidants.

Grape seed extract is made from the seed of the grape and is beneficial for a number of cardiovascular conditions such as poor circulation and high cholesterol. The extract has also been found useful in the treatment of diabetes-related eye disease, loss of vision due to aging, and swelling associated with injury. Currently, GSE is being studied in the treatment of leukemia and Alzheimer’s disease.

Interestingly, past research also points to berries as a solution for colorectal cancer and many other cancers. In one study, the growth of new tumors in mice fed black raspberry decreased by 45 percent and the total number of tumors went down 60 percent. Other research found that foods rich in flavanols (berries, grapes, apples) also reduces the risk of colon cancer.

Advanced Cancer and Grape Seed Extract

The bioactive compounds in grape seed extract selectively target many types of cancer cells. With an increase in colorectal cancer, the findings of this study are timely. By the time most people are diagnosed with the disease, it is in the advanced stages. But thankfully, as mentioned, researchers found that it required less grape seed extract to kill advanced cancer cells than it did cells in the early stage. It is thought that the extract kills cancer cells by a process of oxidative stress.

    My friend who has been on the cannabis oil treatment, has found great relief following it with 2 whole lemons daily

  • Gail Pickholz

    What's the best form and best assimilated GSE?

  • Celia Loftus

    Cannabis has been shown to cure cancer, see "What if Cannabis could Cure Cancer" and "Cancer, the Forbidden Cures." Why is no research being done regarding this? It must be because it really DOES work and would therefore lose Big Pharma millions if no one used the chemotherapy poisons any more.
    I have stage IV Splenic Marginal Zone Lymphoma and am in the middle of my second lot of chemo (this time it's Rituximab and Bendamustine (lovely stuff which is in fact taken from a chemical weapon called mustard gas, used in the war, and has loads of really nasty "adverse events".)
    It's about time some serious action was taken to stop Big Pharma restricting research into cannabis as a REAL cure, we're all dying in our thousands each year, just to keep them rolling in cash.

      Chemo is a class whereas others who have treated cancer are divided.Cant they form a group likewise under one banner and start clinical trial.Only then their voice will be heard.

      • jayar

        duh , clinical trials lead to this info being published

    • Nanita Munoz

      There are tons of clinical studies proving that cannabis kills cancer but until the pharmaceutical companies can synthesize it into a drug they can't make a profit so it will not be available. In the meantime people are suffering, it's so wrong. My friend has secondary cancer, she has just started taking cannabis oil that she made using the Rick Simpson method, he has a documentary Run from the Cure: the Rick Simpson story. He's the lead advocate on in the subject. He also has a Facebook page. All the best. Nani

        I'm having trouble finding this, is it available in book form or can you link me to where it can be purchased Nanita ? Thank you.

      Sorry to hear about your lymphoma. But if you know there are better & safer treatments out there, why are you undergoing chemo a second time? Try something else!

    Interesting why my comment should be deleted and evidently prior to it being read.

  • Chris

    I'm Stage III. How about dosages for all stages? I also heard that there is a danger of interaction with other medications

    • Robert

      There are dangers taking ANY medication. Read the "side" effects. If you don't want interaction between what can heal you and what can kill you, stop taking one of the two. Chose wisely.

        Hallo, my best advice is for you to start using Sunrider products, for more information you can contact and you can be free from all sort of ilneses

      • Z…………

        sorry, I,m from Australia because I address, she is much closer for information
        about Sunrider

  • Peter

    Hi… what would the dosage for stage II. and what for the stage IV be?
