The natural items I am aware of which have had the best success with pancreatic cancer are:
Oleander extract - available as a supplement, patented medicine or a home remedy you make yourself
Black Seed Oil (Nigella Sativa) - is a proven and potent pancreatic cancer fighter
Flaxseed and Cottage Cheese (or quark) from the Budwig Diet - has been used successfully against pancreatic cancer when combined with the other two items above
Pancreatic Enzymes - Has been used with success against cancers by noted alternative doctors Kelly and Gonzalez
Extra care should always be taken with the liver when fighting cancer because first of all, according to the great cancer pioneer Max Gerson cancer only occurs when the liver is impaired to begin with and a successful fight against cancer will release quite a bit of toxins which must be processed and eliminated through the liver. Since your friend's cancer has begun to spread to the liver that is all the more reason to take measures to cleanse and detox the liver, keep it cleansed and the bile ducts open and flowing, and also take measures to protect the liver and regenerate it.
Pancreatic cancer is one of the most difficult and aggressive cancers. I strongly recommend that your friend adopt a comprehensive cancer fighting protocol that includes all of the above elements and more. I would never advise anyone to try to beat pancreatic cancer with a simple one or two item approach.
You can find out much more, including detailed instructions for the liver at:
And I will note that the Yahoo "Oleandersoup" Group I host has members who are successfully fighting pancreatic cancer with oleander, black seed, and Budwig as well as other items you will find on the link above, including special attention to the liver.
