The Facts About Cyanides

In the body, cyanide in small amounts can also combine with another chemical to form vitamin B 12, which helps maintain healthy nerve and red blood cells. In large doses, the bodys ability to change cyanide into thiocyanate is overwhelmed. Large doses of cyanide prevent cells from using oxygen and eventually these cells die.
