Eating amygdalin will cause it to release cyanide in the human body, and may lead to cyanide poisoning. [1] Since the early 1950s, both amygdalin and a chemical derivative named laetrile have been promoted as alternative cancer treatments, often under the misnomer vitamin B 17 (neither amygdalin nor laetrile is a vitamin).

Anti-cancer psychotherapy – a technique [131] claiming that a "cancer personality" caused cancer, which could be cured through talk therapy (e.g. that of the Simonton Cancer Center, [132] Bernie Siegel's "Exceptional Cancer Patients" (ECaP) or Deepak Chopra). Evidence is lacking that cancer cures sold or promoted by Deepak Chopra have any value.
The amygdalin found in apricot seeds has been marketed as an alternative cancer treatment; however, studies have shown it to be ineffective in treating cancer. [3] Cancer Council Australia have commented that "eating apricot kernels in large amounts is not only ineffective for treating cancer, but could also be very dangerous". [8]
Ernst Theodore Krebs Jr. (May 17, 1911 – September 8, 1996) was an American promoter of various substances as alternative cures for cancer, including pangamic acid and amygdalin. He also co-patented the semi-synthetic chemical compound closely related to amygdalin called laetrile , which was also promoted as a cancer preventative and cure.
Extracts from Camptotheca (the "happy tree" or "cancer tree") were used to develop the chemotherapeutic drug Topotecan. Plant sources of anti-cancer agents are plants, the derivatives of which have been shown to be usable for the treatment or prevention of cancer in humans. [1] [2]
Kanematsu Sugiura (1890 – October 21, 1979 in White Plains, New York) was a cancer researcher who spent his career at the Memorial Sloan-Kettering Cancer Center. A pioneer in cancer research", [1] he completed over 250 papers before his death. Sugiura received a number of awards and prizes throughout his life, and retired from the center in 1962.
As a result, the entire antibody, linker and cytotoxic (anti-cancer) agent enter the targeted cancer cell where the antibody is degraded into an amino acid. The resulting complex – amino acid, linker and cytotoxic agent – is considered to be the active drug. In contrast, cleavable linkers are detached by enzymes in the cancer cell. The ...
Amygdalin and a synthetic derivative, laetrile, were investigated as potential drugs to treat cancer and were heavily promoted as alternative medicine; they are ineffective and dangerous. [ 7 ] Some butterfly species, such as the Dryas iulia and Parnassius smintheus , have evolved to use the cyanogenic glycosides found in their host plants as a ...
