Examination revealed a tired-looking patient with vital signs significant only for mild tachycardia of 105 and spO2 95% on room air. The acid hydrolysis of amygdalin yields a single product gentibiose (a disaccharide with β 1-6 linkage). Anti-proliferation of the cells occurred at high concentration of amygdalin, inhibition of migration and invasiveness occurred at the low concentration of the solution. This patient ingested 1500 mg of amygdalin (vitamin B17) as prescribed, which contains approximately 90 mg of cyanide.

All natural cancer therapy—vitamin B. Wilson, B . It has been a subject of debate whether amygdalin causes tumor regression or is it toxic at the rightly administered dose rendering it a toxic chemical rather than a therapeutic drug. Journal of Biotechnology and Biomedicine 3 (2020): 039-049. However, its recent widespread usage was attributed to fraudulent internet sources resurfacing it as the main cure of cancer rather than alternative therapy [6]. Its pharmacological activities have been studied extensively, but its anti-tumor activity is still inconclusive. The β glucosidase which are lactasephlorizin hydrolase (LPH) and cytosolic β glucosidase (CBG) found in the intestinal mucosa cleave glycosidic linkages and act on other compounds like bile and fatty acids to yield carcinogens. Rep 14 (2018): 125-132. It was reported that it caused the cytotoxicity of estrogen receptor (ER)- positive MCF7 cell, MDA-MB-237 and Hs 578T triple negative breast cancer cells (TNBC). Prebiotics are biological molecules while probiotics are organisms that modulate the activities of gut microbiota for the benefit of the host. Total cyanide was measured by enzymatic treatment, steam distillation and colorimetric quantification using the pyridine–pyrazolone method. Amygdalin and laetrile (a synthetic form of amygdalin) are commonly used as complementary or alternative medicine (CAM) for the treatment of cancer.

Hydrogen cyanide is a poisonous gas that does not exist in the seeds but is released in the body by metabolism of amygdalin. Zhonghua Er Ke Za Zhi Chin.

The intestinal β glucosidase can also convert amygdalin to prunasin and no hydrocyanic acid is formed [1]. J. Mild to moderate cases of cyanide toxicity consist of tachycardia, headache, confusion, nausea, and weakness. A 68-year-old patient with cancer presented to the emergency department shortly after her first dose (3 g) of amygdalin with a reduced Glasgow Coma Score, seizures, and severe lactic acidosis requiring intubation and ventilation.
