Historical legends about Lycium barbarum.

During the heyday of the Tang Dynasty, it is said that one day, a group of businessmen from the western regions came to the Silk Road, stayed in an inn at night and saw a woman reprimanding an old man. The businessman stepped forward and asked, "Why did you beat and scold the old man like this?" The woman said, "What does it matter to you if I teach my grandson a lesson?" Everyone who heard it was shocked. It turns out that this woman is over 200 years old and the old man is 90 years old. He was beaten because he refused to obey the family rules and take herbs. As a result, he was senile and his eyes were dim. Surprised, the businessman asked the birthday girl the secret of longevity? When the birthday boy saw that the messenger was full of sincerity, he told him that Lycium barbarum was taken in four seasons. Later, Lycium barbarum was introduced to the Middle East and the West, and it was known as the Oriental God Grass.
