The cyanide contained in almonds is a highly toxic substance that can cause “flash death” when poisoned and is difficult to resuscitate. The amount of cyanide in sweet almonds is very small and is not usually toxic. If you eat a lot of uncooked bitter almonds, you will be easily poisoned. Poisoning manifestations: 1. Generally, dizziness, headache, nausea and weakness appear within half an hour to several hours after eating, and the lighter ones can get better within 4-6 hours. 2. The more serious ones may have abdominal pain, diarrhea, vomiting, confusion, difficulty in breathing, or even general convulsions, shortness of breath or even death. Emergency treatment: 1, vomiting: use fingers or chopsticks to stimulate the back wall of the throat or the root of the tongue, try to vomit up the stomach contents, and then drink a lot of warm water to repeatedly induce vomiting. Drinking mung bean water after vomiting can play a role in detoxification. 2, the more serious symptoms to be immediately sent to the hospital, before drinking some sugar water, also has a certain detoxification effect. In addition, peach kernel, lentil kernel, loquat kernel, plum kernel, plum kernel, cherry kernel, etc. contain cyanide and should not be consumed without processing.
