“Vitamin B17, also called Amygdalin or laetrile, is a glycoside nutrient linked with cancer prevention in alternative medicine practices - and there are reliable claims that it's actually cured cancer. Vitamin B17 is derived from natural food sources and most abundant in seeds of plants of the prunasin family, such as apricots and apples. Laetrile, the extract form of vitamin B17, is most well-known for potentially helping prevent cancer development through the production of hydrogen cyanide. This beneficial compound is released into the body's tissues and targets and destroys mutated cells. Although more formal research is still needed to prove vitamin B17's effectiveness, many alternative medicine practitioners use vitamin B17 to increase immunity. Cyanide is thought to be the main anti-cancer component of vitamin B17 but is not fully proven in clinical settings as of today.”
