In China literature, the first person to record bird's nest was Huang Zhong's Yu Hai in Ming Dynasty. However, the existing version of Yu Hai was supplemented by Huang Xuezhun, a descendant of Hai. Did Huang Zhong write a book about bird's nest? This is impossible to decide. Secondly, see Wang Shimao's Folk Books. Wang said: "Although the bird's nest is unknown, it is already by the sea. Swallows cross the sea, and when they are tired, they jump into the sea, float like cups and sit inside. After a long time, I regained the title of flying. Most of them rely on the sea breeze to anchor at the mountain, teaching people to know the goods. Very, very big! "From its cultural meaning, bird's nest has never been used as food, and even as a therapeutic treasure is unknown. Just as a strange commodity. Later, its contemporary author Tu Benjun said in "Misunderstanding in the Sea of Fujian" that "it is said that in the winter, Eiko built a nest in an island cave with a small fish, and in the early spring of the following year, Yan abandoned the nest and someone went to get it. "It is also said that a swallow took a feather to make a hole in the winter month, then took a Uo Ken room, sealed the house with mud, and suffocated in the middle, forming an air knot. "If you fly away next spring, you will get it. As round as a coconut, you must scrape it with a knife. Remove it and wash it with water. " He also quoted Yu as saying, "Haiyan ... the nest in spring returned to the ancient rock, which is a white seaweed." How to get to Haidao in autumn? Trim the stem and take it, which is called sea bird's nest. Spread with the ship, your family banquet is precious and its price is auspicious. " Tu Shi is a naturalist in Ningbo, Zhejiang, but he still doesn't know much about the Bird's Nest in Fujian. He only said that it could be a "family banquet" compared with Wang Shimao, so he finally said, "Don't trust him until he deals with offshore people." That is, I hope to get in touch with people from the place of origin and know the truth. During the Wanli period, Zhang Xie published a book "Examining the East China Sea", which further improved his understanding of bird's nest. He said: "Swallows eat seaweed, spit it as a nest, lie in stone caves to lay eggs and give birth to chicks, so there is much hair, and foreigners take it by ladder." Some people also say that "Haiyan ... returns to the dangerous ancient rock wall to nest in spring ... the island waits for its autumn, and the porridge is shoveled by pruning, which is called bird's nest, and the feast is precious." It is pointed out that there were four areas producing bird's nest at that time, namely Jiaodian, Zhancheng, Cambodia and Dani (namely Kelantan). According to Zhang's records, bird's nest is not only a rare feast, but also a large number of imports from the above areas. Therefore, in the seventeenth year of Wanli (1587), there was a land tax on imported bird's nest. At this point, bird's nest has become a precious food for people in Fujian and Guangdong. Therefore, the "Suiyuan Food List" has the saying that "bird's nest is expensive, so it is not used lightly". In addition, Shang Dajun's Guangdong Xinyu and Xie's Sea and Land also described the bird's nest in detail. It is said that bird's nest is produced in Dinkaluo, Maliuxia, Longya, Xindang, Wutu and Gabugao, which is now Liucheng, Mali, Wenlai and Yayingka Sanbalang. The areas where Gongbo produces bird's nest in Guangdong Customs Records also include Garba, Maliuxia, Wenlai and Zhancheng. That is, the southern tip of the Malay Peninsula, Indonesia, Borneo and the half island of India, these areas are also consistent with Zheng He's seven voyages to the West. Therefore, Japanese Tian Zhongjing confirmed in his book Eating in China that the bird's nest was brought back to China by Zheng He on his seventh voyage to the West.

After bird's nest became a precious food, it took more than one hundred years to determine its medicinal value through experiments. Its curative effect was first seen in Wang Ang's Compendium of Materia Medica and Zhang Lu's Ben Feng Jingyuan. Wang was a famous clinician at that time, and his curative effect on bird's nest. It was confirmed by long-term clinical trials. "Compendium of Materia Medica" records that "bird's nest is sweet and light, nourishing lung and yin, resolving phlegm and relieving cough. Invigorating deficiency and clearing deficiency is the holy medicine to recuperate fatigue. All diseases cannot be eliminated because of lung deficiency. They can use this to cure. " "materia medica meets the original" says that "bird's nest ... is the most docile person in food. Unfortunately, herbs are not accepted and there are few prescription books. It makes people tired, coughing and spitting red phlegm. Every time they cook with rock sugar, they often get results. But it is suitable for patients with superficial diseases. If the yin fire is strong, the blood will rush upwards. Although it is useless, it is soft and inflexible. " In addition, New Theory of Materia Medica and Seeking Truth from Materia Medica both supplement the curative effect of bird's nest, and Zhao Xuemin's Compendium of Materia Medica is the most detailed. The book contains all the information about bird's nest from the late Ming Dynasty to the Qing Dynasty and integrates it into an article. At this point, it is confirmed that bird's nest has changed from a precious food to a therapeutic treasure. Its curative effect has the functions of nourishing yin, moistening dryness, tonifying middle warmer and benefiting qi. Can cure deficiency. Tuberculosis, cough, expectoration, hemoptysis, vomiting blood, chronic dysentery, long-term malaria, diaphragmatic choking cough, nausea.
