In fact, the Dragon Boat Festival and the Double Ninth Festival in cornus, one is the alternation of spring and summer, and the other is the alternation of autumn and winter, both of which are the seasons when diseases are easily prevalent. This also reflects that our ancestors had the scientific thought of preventing diseases. Cornus is blind to Chinese medicine. China Pharmacy Dictionary explains that this product can be used in both north and south, and "Wudi" is the best medicine, so it is also called Evodia rutaecarpa. The so-called "land of Wu" is the state of Wu in history. The name of cornus also comes from a legend.
According to legend, during the Spring and Autumn Period and the Warring States Period, the weak State of Wu had to pay tribute to its strong neighbor Chu on time every year. One year, the emissary of the State of Wu presented its own specialty "Evodia rutaecarpa" to the King of Chu. The greedy and ignorant king of Chu loved pearls, agates, gold and silver treasures, and simply looked down on this native Chinese herbal medicine. Instead, he thought that the State of Wu was teasing him, so he flew into a rage and refused to allow the envoy of the State of Wu to have a half explanation, so he was driven out of the palace. There was a doctor named Zhu around the king of Chu, who was in close contact with the emissary of the State of Wu. He was busy taking him home to comfort him. The emissary of the State of Wu said that Evodia rutaecarpa is the first-class medicinal material in China, which has the functions of warming the middle warmer to relieve pain, reducing adverse reactions and stopping vomiting, and is good at treating stomach cold and abdominal pain, vomiting and diarrhea, etc. Because of the chronic illness of the stomach cold and abdominal pain of the King of Chu, it was unexpected that the King of Chu was indiscriminate ... After listening, Dr. Zhu sent someone to send the emissary of the State of Wu back to China and carefully kept the Evodia rutaecarpa he brought.
The following year, the King of Chu suffered from the cold and his old illness recurred. His abdominal pain was like a knife, and the group of doctors could do nothing. When Dr. Zhu saw that the time had come, he quickly tortured Evodia rutaecarpa and gave it to the king of Chu to relieve pain for a while. The king of Chu was overjoyed and rewarded Dr. Zhu, and asked what medicine it was. Dr. Zhu described the offering of medicine by the envoy of the State of Wu. After hearing this, the king of Chu was very remorseful. He sent someone to apologize to the prince with gifts and ordered people to plant Evodia rutaecarpa widely. A few years later, the plague in Chu was prevalent, and patients with abdominal pain spread all over the country, relying on Evodia rutaecarpa to save thousands of people's lives. In order to thank Dr. Zhu for saving his life, the people of Chu added the word "Zhu" in front of Wu Yu and renamed it "Wu Zhuyu". Later medical scientists added a cursive prefix to the word Zhu, which was officially named "Evodia rutaecarpa" and has been used ever since.
