There are many reports about "Jibao" in the media, but there is no clear academic explanation for "Jibao". Some people say that "Keppel" is a gallstone of chicken, which is oval in shape, light in weight, golden yellow to yellowish brown in appearance, delicate and shiny. It is also said that "Keppel" is formed when the ovary is inflamed, the fallopian tube is blocked and many egg yolks gather together.
On March 20 16, Ms. yihuang of Hui' an county killed a hen and took out the so-called "chicken treasure" from its belly. I have heard that "Keppel" has no market price, and the price of one gram is between 70,000 and 350,000 yuan. I was surprised after reading it, and even planned to auction it in Shanghai.
"Jibao" is legendary because of its medicinal value. It is said that there are contents in Jibao. If the iron content reaches 5%, it is a first-class Keppel. The' treasures' in animals' bellies, namely' Ma Bao', monkey dates, bezoar and dog treasures, are all recorded as Chinese herbal medicines in Chinese medical books, and are not commonly used Chinese medicines.
