Sanqi (Burke. F.H. Chen is a plant of Araliaceae, which is a rare Chinese herbal medicine and one of the earliest medicinal and edible plants in China. Since ancient times, Notoginseng has been recognized as having remarkable effects of promoting blood circulation, removing blood stasis, reducing swelling and relieving pain, and has the reputation of "gold will not change" and "southern sacred grass". Because the branch is divided into three branches and seven pieces, it is called "Sanqi", also known as Tianqi, Jin Buhuan and so on. In ancient times, it was also called Zhao Shen, Shen Xue, Sanqi, Sanqi, Mountain lacquer, Sanqi and so on. Because it is often excavated in spring and summer, it is divided into "Spring Seven" and "Winter Seven". Because Panax notoginseng belongs to the genus Panax, its effective active substance is higher than that of Panax ginseng, so it is also called "the king of Panax ginseng" by modern Chinese medicine pharmacologists. Panax notoginseng originated from the remains of tertiary ancient tropical plants 250 million years ago. Panax notoginseng has special requirements for the growth environment, which is suitable for the climate of warm winter and cool summer, not tolerant of cold and heat, and prefers the ecological environment of semi-shade and semi-humidity. Therefore, its distribution range is limited to the narrow zone near the altitude of 1500m- 1800m and the north latitude of 23.5 in southwest China, including several places where Wenshan Prefecture of Yunnan Province meets Guangxi and Wenshan. Wenshan Prefecture in Yunnan Province is the origin and main producing area. According to relevant literature, the use history of Panax notoginseng is nearly 600 years, and the cultivation history is nearly 500 years. Deep in the dense forest of Wenshan Zhuang and Miao Autonomous Prefecture, the southwest border of the motherland, there is a kind of sacred grass that "spring seedlings are like green and autumn fruits are like fire". There seem to be hundreds of stories about this magical grass: the hunter accidentally fell off the cliff and broke it. They chewed up a kind of wild grass and applied it to the bleeding place. The wound was sealed like paint and the bleeding stopped. Hunters can walk home with shotguns; The mason hurt the soles of his feet and the pain was unbearable. They mashed the holy grass and bandaged it on the wound, stopping bleeding and relieving pain immediately. Mother's blood collapsed and her life was dying. She took it back from death with a sacred grass. Miao ancestors called it "mountain lacquer", and its magical effect was passed down from generation to generation among the people. Because "Mountain lacquer" is homophonic with "Sanqi", it is recorded as "Sanqi" in circulation. There is also a legend about Sanqi: In ancient times, there was a young man named Zhang Er who suffered from a disease, and his nose and mouth were bleeding. Despite repeated treatments, it was still ineffective. One day, a doctor named Tian passed by. He took out the root of an herb and ground it into powder for Zhang Er to swallow. It wasn't long before the bleeding stopped. Zhang Er's family was very grateful and asked the doctor to leave the seeds of this magical herb. A year later, Zhang Erjia's herbs grew very luxuriantly. As it happens, the only daughter of the magistrate's adult was bleeding heavily, and many treatments did not improve, so we had to post a notice: we can cure the sick daughter and recruit her as a husband. When Zhang Er heard about it, he brought his own herbs. Without saying anything, he took out the herbs and ground them into powder for the young lady to take. Who knows that in less than an hour, the young lady died. The judge was furious and ordered Zhang Er to be tied up and tortured. He was forced to tell the truth. The magistrate immediately arrested Dr. Tian and convicted him of "murder". On the day of execution, Dr. Tian had no choice but to explain to the county magistrate who personally supervised the beheading: "This herbal medicine is effective for all kinds of blood diseases, but it will take three to seven years to be effective. The drugs used in Zhang Er are only one year old and have no medicinal properties. Of course, I can't save the young lady. " Then he asked the officer for a sharp knife and made a cut on his thigh. The blood is DC's. He took the powder out of the medicine bag, took it for internal and external use, and immediately stopped the scab in the stool. Everyone present was shocked, and the magistrate regretted it and had to let Dr. Tian go. In order to remember this painful lesson, people named this medicine "Sanqi", which means that it must grow for 3 ~ 7 years to be useful. Because this medicine was handed down by Dr. Tian, in some parts of our country, Panax notoginseng is also called "Tianqi".
