Apricot kernels contain a lot of vitamin B 17, or Amygdalin, which was present in the traditional diets of African countries, where the sickle cell gene evolved to offer people protection against malaria, which was endemic in the region. Certain traditional foods in the African diet, such as the Cassaba Melon, are rich in vitamin B 17. Those with the sickle cell gene were immune from sickle cell attacks just as long as they stuck to their traditional diets, but since the Standard American Diet (SAD) is devoid of this vital nutrient, the nutritional protection / prevention is gone, and sickle cell attacks occur.
By the way - Apricot Kernels, or Bitter Almonds, are used to make Amaretto Liqueur, and Bitter Almonds / Apricot Kernels, called Xing Ren in Chinese, are what is traditionally used to make Almond Chicken - for those who can read the Chinese characters on Chinese restaurant menus, such as myself, this is quite apparent.

You see, the whole cyanide scare is something that was concocted by the medical establishment just to scare people away from natural cancer therapies that use Apricot Kernel extract. Although the Amygdalin / B 17 molecule bears a close resemblance to cyanide, it does NOT metabolize into cyanide in the human body - that is a lie concocted by the medical mafia.
