  Amygdalin (CAS NO.29883-15-6) is a glycoside initially isolated from the seeds of the tree Prunus dulcis, also known as bitter almonds, by Pierre-Jean Robiquet and A. F. Boutron-Charlard in 1803, and subsequently investigated by Liebig and Wohler in 1830, and others. Several other related species in the genus of Prunus, including apricot (Prunus armeniaca) and black cherry (Prunus serotina), also contain amygdalin. It was promoted as a cancer cure by Ernst T. Krebs under the name "Vitamin B17", but studies have found it to be ineffective.

  Amygdalin (CAS NO.29883-15-6) was first isolated in 1830. In 1845 it was used for cancer in Russia and again in the 1920s in the United States, but it was considered too poisonous. In the 1950s a reportedly nontoxic, synthetic form was patented for use as a meat preservative and later marketed as Laetrile for cancer treatment.

Human poison by ingestion (infant data). Poison experimentally by ingestion. An experimental teratogen. Mutation data reported. When heated to decomposition it emits toxic fumes of NO_x.
