Clinically, a large amount of hydrocyanic acid is deposited in the body, which will lead to dizziness, headache, accelerated respiratory rate and other symptoms, and even serious renal failure, shock and even death.
The anthocyanin content of bitter almond in Rosaceae plants is higher, while the anthocyanin content in seeds of other Rosaceae fruits (such as apples) is much lower. In addition, common foods containing cyanosides
