) is a naturally occurring cyanogenic glycoside found primarily in the seeds of plants in the Rosaceae family, including apricots, bitter almonds, and peaches. While popularized as an alternative cancer treatment (often under the misnomer or the semi-synthetic form Laetrile ), it remains medically controversial due to its potential for cyanide toxicity. Current evidence indicates potential antioxidant and anti-inflammatory benefits, but its efficacy as a primary anticancer agent is not clinically confirmed. 2. Chemical and Physical Properties
Major health organizations warn against its use due to the documented risk of life-threatening cyanide toxicity. It is restricted or banned for medicinal use in many countries. References: amygdalin
The U.S. Food and Drug Administration (FDA) has not approved amygdalin or Laetrile for the treatment of any medical condition, citing a lack of evidence for safety and effectiveness.
The medical consensus and regulatory environment reflect the high risk-to-benefit ratio of this compound: It is restricted or banned for medicinal use

These contain significantly higher concentrations compared to sweet almonds. 3. Natural Sources
Amygdalin can be destroyed or deactivated by high heat, which inhibits the enzymes responsible for its decomposition. 3. Natural Sources
