The story of apricot kernels and their use in natural health goes back to the mid 1800’s, when amygdalin was first isolated in 1830. Apricot pits are a natural source of amygdalin, which is often given the misnomer of vitamin B-17. Other sources include the seeds of other fruits and a few raw nuts.
Another term you might have seen in regards to apricot kernels is laetrile. This is simply the patented synthetic form of amygdalin (a.k.a. vitamin B-17). Swanson Health Products sells organic raw apricot kernels but recommends that daily consumption not exceed 8 per day.
