According to textual research, Yang Wanli, the magistrate of Zhangzhou in the Song Dynasty, wrote Ode to Loquat: "A big leaf has long ears, and a tip is as full as a plate. Litchi is full of stones, but kumquat is sour. The rain depressed the weight of the branches and the flesh was cold. Whether Changqing is here or not, don't send him as a garden official. " In Ming Dynasty, Chen Dao and Huang recorded in Eight Min Zhi (149 1): "Loquat is reed withered, its leaves are like donkey's ears, and it does not wither in four seasons, and there are crops in Minquan, Zhangzhou, Ting, Yan, Shaoxing and Funing". "Zhangzhou City Records" (Chapter 4 Fruits): "Zhangzhou has cultivated loquat for more than 700 years, mainly produced in Yunxiao County, accounting for 50% of the city's output. There are 22 local varieties, including Redmi (red meat long variety and red meat round variety), Putian Pak Lei, Zhejiang Dahongpao, sweet loquat, Taiwan Province variety, early-maturing variety, sour loquat, Jiaotiaobaisha, Jiefang variety, Dazhong, Fuyang, Dacheng No.4, Japanese Zaosang, Dongben Xiahua, Shanlihong, Gu Hong, Meixiaxia and Shanloquat. The long variety of red meat (also called Changhong) produced in Yunxiao County went on the market in late February, which was earlier than the varieties from Taiwan Province, Guangdong and Putian, and was praised as "the first fruit of spring".
Li Shizhen, a medical scientist in Ming Dynasty, recorded in Compendium of Materia Medica: "Loquat is a good medicine for harmonizing stomach, reducing qi, clearing heat and relieving summer heat." Loquat was rated as the "crown of fruit" because of its magical effect, and was often used as a tribute in history. The flowers and leaves of loquat can be used as medicine. Loquat leaves have the functions of clearing away lung-heat, regulating stomach, lowering qi and resolving phlegm, and are important drugs for treating lung-qi cough.
Lin Kaichun, a sage in Xiao Yun, was edited by the Hanlin Academy during the Wanli period of the Ming Dynasty, and was a political advisor to Hu Guangyou, a political advisor in central Zhejiang, and a deputy envoy of Hu Guang. There are many verses describing loquat cultivation in his manuscript "Collection of laymen in Yunshan" (a collection of history, art and literature). There are 260 kinds of prescriptions in Yunshan College, Miaomiao, Lincaichun, Xiao Yun, and most of them use loquat leaves as medicine. Thus, Xiao Yun was rich in loquat in the Ming Dynasty, and its efficacy was well known.
During the Guangxu period of the Qing Dynasty, Qiu Jin's grandfather Qiu Jiahe had two bosom friends in Xiao Yun (A.D. 1878 and A.D. 1889). He often placed loquat flowers, loquat leaves and loquat roots in his residence for the people to boil water for drinking, so as to nourish yin, reduce fire, clear the lung and eliminate phlegm, and treat colds and coughs, lung and stomach heat, dry mouth and other diseases. He often said to the people, "This is a folk medicine, which can save money and cure diseases."
