Bitter apricot kernels or almonds apply for their cyanide content as prohibited cores. Since childhood has already taught us that. But has a cancer already "slammed", then things look different. These wonderful cores should have the ability to destroy cancer cells. Of course, one should not too much of it eat- more than 40 pieces, otherwise it could lead to a cyanide poisoning. These cores show is really recommendable. The cores are only sweet before then wide makes slight bitterness in the mouth in perfect condition, the taste. I eat them preventively - 12 pieces a day, I liked it.
