First for pancreatic cancer she needs 3 tsp of the oil, not the seeds. 1 tsp of oil is equal to 2 and 1/2 tsp of seeds, so technically she needs to have 7 and 1/2 teaspoons of seeds. She also needs lufft and olive leaf. This is part of my complete protocol and on a raw diet. I do not recommend garlic period as it destroys brain cells, ie Bob Beck's protocol.
The barley is very good. I use raw organic barley in my lufft along with red grape seeds.
I and most cancer doctors, ie Dr. Johanna Budwig are vastly against fish or red meat. I would drop the fish most definitely.
AS you may know black seeds have been proven effective on liver and kidney diseases. I believe Manuka honey is good or a good raw honey.
