Shepherd's purse, which comes from the cruciferous family, is widely distributed in my country. The Chinese have a long history of eating shepherd's purse. The Book of Songs says: "Who makes tea bitter? It is as sweet as shepherd's purse." It can be seen that the ancients knew the deliciousness of shepherd's purse very early. There is even a saying among the people that "after eating shepherd's purse, all vegetables are not fresh." Shepherd's purse has high nutritional value and is rich in vitamins, minerals, proteins and other ingredients. It is particularly worth mentioning that shepherd's purse is a natural calcium supplement. Its calcium content is nearly three times that of the same weight of milk. It can be used as a good source of calcium in the daily diet and is very suitable for people with lactose intolerance to supplement calcium.

Shepherd's purse also has high medicinal value. There is even a saying that "On March 3, shepherd's purse is a panacea." Shepherd's purse was first recorded as a medicine in "Famous Doctors' Records" written by Tao Hongjing, a doctor in the Wei and Jin Dynasties. Chinese medicine believes that shepherd's purse is sweet and mild in nature, and has the effects of clearing heat and stopping bleeding, calming the liver and improving eyesight, and clearing heat and promoting diuresis.
