I don't think it's quite like the prickly lettuce, the flower in the picture is supposed to be yellow, while the flowers of prickly lettuce are usually purple or white.

The prickly lettuce as a kind of "vegetable", inevitably can not escape the fate of being eaten, but "prickly" in the front, in the end can not eat, how to eat? And became a problem. And these doubts can be answered after revealing its nature.

The prickly lettuce, is its scientific name, however, its alias "thistle grass" seems to sound more formal, in addition, it is also called in different areas of the "gun knife vegetable", "prickly dog's tooth It is also known in different parts of the world as "gunnery knife", "prickly dog's tooth", or "little devil's hen". As a perennial herb in the thistle genus of the Asteraceae family, it is a highly prized wild vegetable in nutritional terms. This wild vegetable not only has extremely high food value, its medicinal value can not be ignored.

But because it is very adaptable to the environment, but also a wild grass, it is easy to flood into the local ecosystem caused by a certain impact, so it is the environmental protection personnel are very headache species. So, what kind of origin does prickly vetch have? And how did it develop into what it is today? What are the stories of the time it has ****ed with humans?

The origin and development of the prickly lettuce

The real derivation of the prickly lettuce is the geological history of the time period of millions of years ago, the first prickly lettuce may have become a fossil, or perhaps not even the opportunity to become a fossil, it was annihilated in the sea of sea and land. The earliest recorded prickly lettuce had a name three thousand years ago. This is Sima Qian's great work of "the Records of the Grand Historian" for future generations of people can be verified traces left.

However, in the general history of so much information recorded in the ancient books, no matter the length or importance, Sima Qian can not and will not be a weed and set up a separate biography, so this "clues and clues" although the origin of the prickly lettuce become traceable, but there is still a lot of controversy voice.

The Records of the Grand Historian (史记), in the year one thousand and sixty-six B.C., after King Wu had conquered the Zhou Dynasty, King Zhaogong was appointed in Yan (燕), which is the area of Beijing nowadays. He also named the capital city of Yan "Ji" (蓟), which is the word for "artichoke".

According to China's customary character formation, the cursive character above means that it has a great relationship with plants, which means that "蓟" was already thistle at this time. Thistle is an alternative name for the prickly vegetable, and we can naturally conclude that the prickly vegetable had already appeared in the daily life of the ancient people at this time. However, the voice of the opposition also has its own reasons: from ancient times to the present, even ten years ago the meaning of the word with the present still has a lot of discrepancies, in 3,000 years ago "artichoke" refers to is the alias small thistle prickly lettuce, or at that time prickly lettuce is the present prickly lettuce is not yet known.

But by the end of the Han Dynasty, the book was written in the "Famous Doctors", to "small thistle" as the name of the prickly lettuce is a real authentication, at this time it is not only in the ancient books have the name, and even medicinal flavors and attribution and function of the main treatment of the book and also be recorded down, from now on, this has always been the poor people used to eat wild food. From then on, this has been the poor people used to spend their days and eat wild vegetables, by virtue of the medicinal properties of the medicinal effects were discovered, relying on the medical books of successive dynasties to get a relatively coherent historical documentation.

During this period of time, the name of the prickly vegetable has always changed, but after scholars of traditional medical history, has been combed through its development changes in addition to a clear vein. In the Collected Notes on the Classic of Materia Medica (本草经集注), the prickly lettuce is called "cat thistle"; and in the Classic of Materia Medica (本草图经), it is called "green thorn thistle" and "thousand needles grass", with the following words "The juice of the raw root is used to treat vomiting blood, carp blood, and lowering blood."
