Apricot kernels are still all the rage in homeopathic remedies-- largely marketed for their source of protein, vitamins, and carbohydrates. But alas, their chemical compound hasn't wavered.
Amygdalin, also known as Laetrile, is naturally present in all apricot kernels, and it can be poisonous when ingested in large doses. That's because it converts to cyanide after consumption. And it doesn't take much: exceeding 3 small apricot kernels can elevate cyanide in your body. For toddlers, that's half of a small kernel.
Cyanide poisoning can cause nausea, fever, headaches, insomnia, and falling blood pressure, to name a few side effects. In extreme cases, it's fatal.
Don't believe it? Check the nutrition labels on apricot kernels distributed in stores and online-- you'll find warning labels against eating too many kernels and risking poison. Children and pregnant women should not ingest at all.
