Daylily


    





Daylily, also known as golden needle vegetable and true gold flower, is a perennial herb of the order Liliales, family Liliaceae. Because of its delicious taste and its richness in vitamins, phosphorus, calcium, iron and other substances, it has become a well-known delicacy.




Dried daylily is non-toxic,

while fresh daylily is rich in colchicine, which is oxidized in the body into the more toxic colchicine derivative, stimulating the digestive system and causing poisoning symptoms.

After eating fresh daylily, patients develop dry throat, heartburn, nausea, vomiting, abdominal pain, diarrhea within a few minutes to more than 10 hours, and in severe cases bloody stool, blood in urine, oliguria and other discomforts, indicating poisoning.





Dried daylily is non-toxic




Eating dried daylily, according to research

Dehydrated daylily steamed at 95°C for 60s can achieve the best edible value and safety

; if you really must eat fresh daylily, eat less than one liang (50g) at a time, and soak it in clean water for 2h before eating to dissolve out as much colchicine as possible.





Handling of accidental ingestion

:

Induce vomiting immediately, then send to hospital; with timely treatment the prognosis is generally good.






Houttuynia cordata








Houttuynia cordata, also known as zhe'ergen, pig nostril, dog point ear, etc., is a herbaceous plant of the family Saururaceae. Houttuynia cordata is widely recorded in traditional Chinese medicine classics,

and has effects such as clearing heat and detoxifying, promoting diuresis and reducing swelling, inhibiting bacteria and fighting viruses, and boosting immunity. It is common as medicine and even more common on the dining table.




Oral use of Houttuynia cordata occasionally causes dry mouth, heartburn, palpitations, hand tremor,

and after overdose, nausea, vomiting, dizziness, heavy sweating, difficulty breathing, coma, and shock. Houttuynia cordata has low toxicity and contains aristolactam; long-term heavy consumption can cause irreversible kidney damage and lead to upper urinary tract urothelial carcinoma.

Since June 2006, Houttuynia cordata injection has been suspended.








Handling

:

Acute discomfort is mainly allergic, and supportive symptomatic treatment is the main approach.






Ginkgo nut







Ginkgo nut, also known as ginkgo, and also called duck neck, lingmian, Buddha's fingernail, is the seed of the ginkgo, a deciduous tree of the genus Ginkgo, family Ginkgoaceae. Inside the shell is a yellow-white fleshy kernel, rich in nutrients, sweet and fragrant, and it can be boiled or stir-fried.




The toxicity of ginkgo nut is greatest in the green embryo

,

The kernel contains trace amounts of cyanogenic glycosides, and eating too many can easily cause acute poisoning.

Its toxin is soluble in water and strongly toxic; exposure to heat can reduce the toxicity, so those who eat it raw have more pronounced poisoning symptoms.







Poisoned patients mainly show central nervous system and gastrointestinal symptoms, and occasionally peripheral nerve dysfunction, with dizziness, dry mouth, fatigue, nausea, vomiting, abdominal pain, diarrhea, and even visual rotation, fear, listlessness, convulsions, twitching, etc. Onset is generally 1-12h after eating, and in some cases up to 16h. The younger the age, the more prone to poisoning; for infants, eating 10 in a row can be fatal, and for children aged 3-7, 30-40 can be fatal.




The key is a very... very small amount!

(Putting a few in a stew pot is enough, peel off the green embryo and throw it away, and don't let children eat it carelessly; as for those who go eat ginkgo leaves, that is even harder to understand; just one word: it will also cause poisoning!)





Handling

:

Induce vomiting, and send to hospital immediately.
