Apple seeds kill you if you chew 200 or more seeds how?

Apple seeds contain amygdalin, A substance that release cyanide into the blood stream when chewed and digested. However, Apple seeds in small amounts do not contain enough cyanide to cause harm. If you chew and eats 200 seeds you will just die in a minute.                                                                                                                       It is better to spit out seeds to avoide any potential issues.
