Li Wanping, a nutritionist, pointed out that in the Notes on Materia Medica, "Hemerocallis has a sweet taste, which makes people happy, happy and forgets worries." Warming water, removing dampness and clearing stranguria, quenching thirst and vexation, opening the chest and opening the diaphragm; it makes one feel calm and free from depression.”
From the point of view of modern nutrition, can eating golden needles really relieve anxiety and relieve depression? Li Wanping said, according to a document published in the Journal of Traditional and Complementary Medicine in 2013, in the forced swimming experiment, the ethanol extract (DFEtoH) and rutin (rutin) extracted from dried golden needles , also known as rutin) can make the inactive time of rats significantly lower than that of the control group, and the swimming time is significantly increased.
The so-called "forced swimming test" refers to placing mice in a glass container filled with water to test whether antidepressants are effective by swimming and struggling to stand still. In addition, in many research papers from 2017 to 2019, it is also indicated that rutin is an active ingredient with antidepressant effect.
Experiments in mice in 1998 and humans in 2016In clinical studies, it has also been found that golden needles can help improve sleep conditions. Among them, in the 2016 study, subjects who were given dietary supplements mixed with rosemary and golden needles not only felt better rest quality, but also had better concentration and alertness, and felt dull and uncomfortable. Frustration levels were reduced.
Taiwan's fresh golden needles are prolific from August to September each year. Because they are not resistant to storage, farmers will pluck the buds before the flowers bloom, and then dry and process them to make them dry. Taste. If these two kinds of gold needles are compared with the same weight, However,
Li Wanping reminded that fresh golden needles contain "colchicine", which may cause abdominal pain, vomiting, diarrhea and other gastrointestinal symptoms after entering the human body;
As for dry gold needles, due to the processing, the colchicine has been destroyed, so don't worry;
Many people are worried about the sulfur dioxide added during the processing of gold needles. When choosing dry products on the market, you may wish to follow the following principles:
The color should not be too bright, it should be light brown or black. There is no odor such as rancidity or potion, and ideally it smells slightly floral. There should be a dry feeling when touching, no moisture absorption and stickiness.
In addition, when purchasing, you should choose products with complete packaging, clearly marked, and preferably with the "Taiwan Golden Needle" label with a green bottom chrysanthemum thread, to confirm the safety of the source, and eat with relative peace of mind! According to my country's "Scope of Use and Limitation of Food Additives and"Specifications and Standards", selecting gold needles with sulfur dioxide residues less than 4.0 g/kg, generally do not need to worry about food safety issues.
To effectively remove gold needle sulfur dioxide, it is recommended to follow several steps to clean:
After the gold needle is unpacked, rinse it once with clean water, put it in a pot and add about 20 times the amount of water to the gold needle. The best water temperature for soaking gold needles is 45°C. Add a little white vinegar to the water to help eliminate sulfur dioxide. : The whole soaking process takes about 20~30 minutes, but the water needs to be changed once after 10 minutes of soaking.
According to the experimental results of the laboratory of the Taipei City Government Health Bureau, it is found that more than 90% of the sulfur dioxide residue can be removed by doing this, and it can be cooked in a pot after draining!
Li Wanping added that in fact, there are many varieties of golden needles cultivated in Taiwan at present. Among them, in recent years, the tail end of general non-sulfur golden needles will be dull due to residual natural melanin, so just wash the surface with water before cooking. In order to maintain the crispy taste, do not heat it for too long when making soup, just add it and cook for a while before serving.
