There have been quite a few speculations that Apricot Kernels cure cancer. Are they really true? We give you a few more details on its characteristics. 

An apricot kernel is the seed of an apricot, and is often called a "stone". It is known for containing amygdalin, a poisonous compound. Together with the related synthetic compound laetrile, amygdalin has been marketed as an alternative cancer treatment. 

However, scientists have warned that a compound in the apricot kernel converts to cyanide in the body at levels that could be harmful.
Amygdalin was isolated in 1830, and first used as an anticancer agent in Russia in 1845. It is found in the highest concentrations and with the most effective accompanying enzymes in apricot seed kernels. Laetrile is a synthetic version of amygdalin. It was patented in the United States but has not been FDA-approved as a cancer treatmen.. However, laetrile, amygdalin, “vitamin B17,” and apricot kernels are all sold as dietary supplements, and all can be potentially toxic. 
When amygdalin is eaten, it converts to cyanide in the body. Cyanide is a fast-acting, potentially deadly chemical.

Cyanide prevents the cells in the human body from using oxygen, which kills them. As the heart and the brain use a lot of oxygen, cyanide is more harmful to those than other organs.
Research suggests that 0.5-3.5 milligrams of cyanide per kilogram of body weight can be potentially lethal.
A lot of people recommend cancer patients to consume Apricot Kernels, but eating a larger amount can also lead to cyanide poisoning.

We suggest you consult your doctor, before taking any steps for the same.
