Food is the best preventive measure for the health concept of homology of medicine and food in China, so we will eat all kinds of food with health care function during the Dragon Boat Festival, which is different in different regions. Among them, the custom of eating "Huang Wu" comes from the Han nationality in the south of the Yangtze River.
The food in Huang Wu includes Monopterus albus, yellow croaker, cucumber, salted duck eggs and realgar wine. Monopterus albus, cucumber and yellow croaker are seasonal tonic foods for the Dragon Boat Festival. Monopterus albus has the functions of tonifying deficiency, expelling wind and dampness and strengthening bones and muscles. Cucumber has the effects of clearing away heat and toxic materials, quenching thirst and promoting fluid production. The yellow croaker has the functions of appetizing, strengthening the spleen, tonifying deficiency and promoting blood circulation. It is a nourishing food for patients and postpartum, so it ranks among the best in Huang Wu.
Realgar wine has the functions of killing insects, rats and ants. It was not only used as a drink when snakes, insects, rats and ants were rampant during the Dragon Boat Festival in May of the lunar calendar, but also sprinkled a little around the courtyard wall when building houses in ancient times, which had the effect of expelling snakes, insects, rats and ants, and even the ancients imagined it as a panacea for exorcism. At this time, everyone can make up the picture that Xu Xian, who is not very reliable in the legend of the white snake, makes the white snake show its true colors with realgar wine.
Salted duck eggs do not have the efficacy of expelling worms and killing viruses, but they have the efficacy of nourishing yin, nourishing the heart and clearing the lung, so they are especially suitable for nourishing the body in the May of the lunar calendar, when yang is strong and yin begins to breed.
Many people will wonder why China people like salted duck eggs and preserved eggs, but don't like salted duck eggs and goose eggs. In fact, it also contains profound Chinese medicine theory. Because eggs are flat and goose eggs are warm, eating them has little effect on the body, but ducks usually place orders from midnight to before dawn, and hardly lay eggs during the day. According to the theory of the integration of man and nature in traditional Chinese medicine, this kind of egg is purely negative and cold, which will do great harm to the body, especially for people with physical diseases, and it is even more inedible. Therefore, after bad preparation and pickling, turning harm into benefit is not only harmful to the body, but also can treat diarrhea. However, people with physical diseases are still not allowed to eat poorly prepared and salted duck eggs.
Therefore, not only do you eat salted duck eggs during the Dragon Boat Festival, but even if you eat duck eggs every day, you should eat them salty or poorly cooked. But from the point of view of modern nutrition, this kind of food also has some disadvantages. It is best not to eat a few salted duck eggs at a time. When eating preserved eggs, it is best to eat some foods with high protein content, high calcium content and high iron content to drive away lead, and it is best not to overdo it.
