The gourd head, the fat intestine at the junction of the pig's large intestine and the small intestine, is called the gourd head because of its contraction. The gourd head blisters are made from this section of the intestines and mashed sputum plus other excipients and seasonings with boiling broth (sparkling).

The gourd head has a long history. It was the earliest food of the Tang Dynasty, and it is still a famous food in Xi'an. As early as in the Tang Dynasty, Chang'an (now Xi'an City) in Beijing had a food called “Fried White Intestine”, which was made with pig intestines. According to legend, the ancestral home of Jingzhaoyuan (Shaanxi County, Shaanxi Province), the famous doctor of the Tang Dynasty, Sun Sizhen (known as the drug king), his medical attainments are very high, there are many medical monographs, and there are many studies on diet medicine, among which "It is his monograph on diet. One day, he even ate a "fried white intestine" in a small shop in Changan, Kyoto, and took a few mouthfuls from the bowl. He felt that there was a sigh of scent that went straight to the nose, and the mouth was greasy and tired. Taste, ask the owner, I know that it is not made. Sun Sizhen said to the owner: "The intestines are gold, gold and raw water, so there is the power to reduce fire and cure thirst. The belly is soil, centered, and it is the basis of Buzhongyiqi and body-building. Although it is good, it is improperly modulated. It’s also awkward.” Therefore, he took the medicines such as Xi Daxiang, Shangyuangui, Hanyinjiao and other aromas that could be used to remove the greasy medicine from the medicine gourd that he carried with him, and gave it to the owner together with the medicine gourd. The owner put these spices in the pot, and the scent is overflowing, and the taste is greatly increased. This small business has been booming since then. The store did not forget the guidance of the doctor, and hung the medicine gourd to the front of the door, and renamed the "fried white intestine" sold as "the gourd head".
