Jishuitan Hospital traditional Chinese medicine room visit four Huaiyao producing areas in Jiaozuo, Henan Province

On a weekend in December 2013, under the leadership of director Xu Baohai, the traditional Chinese medicine room of Beijing Jishuitan Hospital visited the four Huaiyao producing areas in Jiaozuo, Henan Province Huai Dihuang, Huai yam, Huai Niuxi and Huai chrysanthemum, which are rich in ancient Huaiqing mansion (now Jiaozuo, Henan Province), are collectively referred to as the "four Huai herbs", with the reputation of "Chinese medicine" and the effect of "Huai Shen" Since ancient times, "four Huaiyao" has been listed as genuine medicinal materials Ancient and modern medical scientists call it top grade Jiaozuo area has nearly 3000 years of history of planting four Huaiyao, known as the "hometown of Huaiyao" The special natural conditions such as soil, sunshine, climate and traditional cultivation techniques of pharmaceutical farmers in Jiaozuo area have created the quality of "four Huaiyao" which is more authentic than other similar products in other areas Its unique efficacy and nourishing effect are well known at home and abroad Huaiyao culture has a long history In the 54th year of Qianlong reign of the Qing Dynasty, fan Zhaoli, the county magistrate of Hanoi, Huaiqing Prefecture, praised it with his poem: "villagers grow medicine as a career, and the medicine garden will boast the truth Dioscorea zingiberensis is high, and Rehmannia on the other side reflects chrysanthemum " This poem truly depicts the historical scene of people planting "four Huai medicine" in ancient Huaiqing Prefecture A group of people came to the Jiaozuo yam, Rehmannia planting land, the field ridges in front of them At this time of winter, although the temperature in Henan is warmer than that in Beijing, they have to wear thin down clothes But in the yam field, the pharmaceutical farmers are digging yam with spades in full swing The yam field is a pit with a depth of more than one meter There are yams dug beside the ridge According to the druggist, the planting rule of yams is that they have long leaves on the top and long leaves on the bottom Yams can grow up to one meter and five long, and all the trenches dug in the ground are one meter and five deep, leaving enough room for yams to grow down One of the most important characteristics of genuine Huai yam is that it can't be planted continuously Because the rhizome of Dioscorea opposita has a strong absorption capacity for the relevant nutrients in the soil (so-called "soil capacity"), it can only be planted once in five years in the same land, and only other common crops can be planted within five years after harvest, such as re planting Dioscorea opposita, with extremely low yield and quality Another special product of huaiqingfu, huaidihuang, which also uses large rhizomes as medicine, has more characteristics It can't be "repeated" in eight years Because it can not be "stubble" characteristics, it highlights the "four pregnant medicine" precious A group of people took the spade from the druggist, and the scholar druggist began to dig yams The root of yam is long and thin It's easy to be cut because of its poor strength at the beginning Yaonong said: "yams stand upright and grow underground They should be excavated from the side Because yams are long and deeply buried, they often need to be dug down nearly one meter to be dug completely Patience is needed..." Maybe at the beginning, although we have enough energy, we can't dig out yams Some of us can dig out yams, but we always cut them off Slowly, after mastering the method of digging, one root of yam was dug out by everyone, and every time a long yam was dug out, there was always a cheering voice Then we visited and studied the processing technology of four kinds of Huaiyao After a day of practical activities of digging yams and visiting, we not only learned the common sense of medicine in books, but also experienced the joy of labor and harvest This activity left a memorable impression on everyone.
