As a famous traditional flower in China, chrysanthemum is not only a symbolic plant in autumn, but is also widely used in tea drinks and traditional Chinese medicine. However, the discussion on whether chrysanthemums are poisonous has always been controversial. This article will combine scientific research to reveal the dual attributes of chrysanthemums. Scientific analysis of chrysanthemum toxicity: variety differences and toxicity manifestations Among the more than 200 chrysanthemum species around the world, about 70% are biotoxic. The pyrethroid compounds contained in its flower heads are both natural insect repellents and potential allergens. Contact with fresh petals may cause skin redness, burning pain and other symptoms, and these reactions are often wrongly judged as common allergies. Mechanism of human poisoning response Chrysanthemum toxin acts by inhibiting sodium ion channels in the nervous system. Typical symptoms include: burning sensation at the contact site (occurring within 30 minutes), local swelling (lasting for 2-3 days), and sporadic rash (probability of about 15%).). Medical statistics show that 90% of cases can be alleviated with cold compresses and antihistamines. High temperature is an effective detoxification method: steaming at 80 ° C for 10 minutes can degrade 80% of the toxin, and baking at 120 ° C can completely eliminate the toxicity. This is the fundamental reason why commercially available chrysanthemum tea is safe to drink. Formal processing can zero the toxicity of chrysanthemum. Toxicity assessment of chrysanthemum. Experimental data from wild and cultivated varieties show that the toxicity intensity of horticultural chrysanthemum is 3-5 times that of wild varieties. The risk of exposure to potted chrysanthemums in the home is higher. It is recommended to wear gloves for pruning operations and wash them with soapy water immediately after contact. Guidelines for Safe Eating of Chrysanthemum Incompatibilities explain in detail that when chrysanthemums are eaten with high-protein foods, they may produce compound toxins. Special attention should be paid: ·Prohibition of collocation: chicken (increases the burden on liver metabolism), pork (produces sulfides)·Combination with caution: celery (enhances neurotoxicity), seafood (causes gastrointestinal cramps) Scientific consumption recommends choosing processed products from regular channels, and the daily intake should be controlled at 5-10 grams of dried flowers. Attention for special populations: Pregnant women should reduce the frequency of drinking, and patients with autoimmune diseases should consult a doctor.
Chrysanthemum is a representative of the homology of medicine and food, and its toxic characteristics remind us to scientifically understand plant properties. Through correct processing and reasonable compatibility, risks can be avoided and its health preservation value can be fully exerted.
