The Effects and Taboos of Daylily
As a traditional plant with both edible and medicinal values, daylily holds a special place in Chinese culinary culture. This article analyzes its nutritional components and medicinal properties from a scientific perspective and elaborates on the food taboos that need special attention.
Nutritional Value Analysis of Daylily
Detailed Explanation of Edible Effects
Every 100 grams of dried daylily contains 14.1 grams of protein, 463 milligrams of calcium, and 16.5 milligrams of iron, and its beta-carotene content is 10 times that of tomatoes. The unique dietary fiber can promote intestinal motility, and the contained aspartic acid has a natural flavor-enhancing effect. After professional processing, it can be used to make classic dishes such as daylily-stuffed pork and cold jellyfish salad.
Analysis of Medicinal Value
Modern pharmacological research shows that the extract of daylily can inhibit Staphylococcus aureus by 82%. The contained colchicine derivatives can alleviate the symptoms of gout, and beta-sitosterol has significant anti-inflammatory effects. It is commonly used in traditional Chinese medicine clinics to treat symptoms such as postpartum lack of milk, insomnia, and amnesia.
Food Taboos of Daylily
Risk of Poisoning from Fresh Product
Fresh buds contain 0.2-0.4% colchicine, and adults may be poisoned after ingesting 20 milligrams. It is recommended to use the ancient method of "boiling three times and drying three times": first boil in boiling water for 3 minutes to remove 70% of the toxins, repeat three times, and then dry and store. Experimental data show that this method can reduce the toxin content to a safe range.
Taboos for Special Populations
Clinical statistics show that the probability of symptoms worsening after asthma patients consume it reaches 65%. Gastroenterology experts suggest that patients with gastric ulcers should not consume more than 20 grams per day, and people in the postoperative recovery period should completely avoid it. Those with allergic rhinitis need to undergo allergen testing in advance.
Food Combination Taboos
Consuming with high-purine ingredients (such as geese meat containing 376mg/100g of purine) will worsen gout symptoms. Combining with cold ingredients (such as turtle meat) can easily cause diarrhea. In traditional Chinese medicine diet therapy, it is often combined with neutral ingredients like black fungus and yam to form nutritional complementation.
From the "Shen Nong Ben Cao Jing" of the Han Dynasty to modern nutritional research, daylily has always been a typical representative of food and medicine being the same source. Mastering its processing methods and food taboos correctly can not only exert health benefits but also avoid health risks. It is recommended that consumers choose dried products with SC certification and control the daily consumption within 30-50 grams.
