Why does honey cause poisoning?

Li Shizhen said in Compendium of Materia Medica: "If you don't eat raw honey in July, you will get cholera." It is now known that the toxic reaction caused by honey is related to the poisons contained in plant nectar. Because there are many kinds of plants, the toxic components contained in them are also different. Therefore, the toxic substances and poisoning symptoms that cause "honey poisoning" are more complicated.

The honey collected from the nectar of Gelsemium elegans contains gelsemin A; Honey collected from Davidia involucrata nectar contains glycosides: honey collected from Solanaceae and Datura stramonium contains belladonna alkaloids and scopolamine; Honey collected from Tripterygium wilfordii (Cordyceps sinensis), Malus kunmingensis (Celastraceae) and Celastraceae (Celastraceae) contains toxic substances, most of which are easily poisoned when eaten.

Poisoning symptoms caused by honey containing tripterygium wilfordii and Tripterygium hypoglaucum mainly include dry mouth and bitter taste, dark lips and tongue, headache, numbness of limbs, nausea and vomiting, abdominal pain and diarrhea, and in severe cases, tarry stool. The poisoned person has palpitation, chest tightness and facial edema. The examination showed that blood pressure decreased, heart rate slowed down, heart sounds weakened, arrhythmia, cyanosis of mouth and lips and hepatomegaly appeared. Urine test showed protein. If you eat the poisonous honey of azaleas, you will get sick within a few minutes to 2 hours. Poisoning symptoms include tingling, fatigue, dizziness, nausea and vomiting, blurred vision and so on. , should be treated in time.

It is generally believed that eating honey in summer, especially in dry weather. Poisoning is easy to happen, especially for people who eat raw honey. At present, there is no specific treatment for honey poisoning, mainly in prevention. Honey supplied in the market is generally safe and reliable after food hygiene inspection. But if you go directly to the bee farm to buy honey, you should pay attention to whether the color, fragrance and taste are abnormal. You can try a little honey with the tip of your tongue. Honey containing toxic alkaloids often has bitter, hemp, astringent and other smells. Do not buy food.
