China is the first place to eat gold foil in history. As early as the Qin and Han Dynasties, the rich in China had records of eating gold foil and powder. In modern times, eating gold foil is also very popular in Japan and Southeast Asia. The pure gold with the purity of 99.99% was physically vaporized to make it evenly dispersed into small molecules, and then these small molecules of gold were stacked again to form food additive gold foil by accurately controlling molecular epitaxial stacking.

1983, the Codex Committee of Food Additives of the World Health Organization officially listed nine thousand nine hundred and ninety-nine's natural pure gold in the category of food additives and named it Table ANo. 3 10.？

The eighth category of minerals and trace elements, a new food resource issued by the Ministry of Health of China, defines the edible function of gold foil.

The medical value of gold foil has a long history. For example, Niuhuang Angong Pill, Niuhuang Qingxin Pill, Niuhuang Jiangya Pill, Wuji Baifeng Pill and Dahuoluo Pill in Tongrentang in China are all prepared or wrapped with gold foil. In China, gold foil is also a folk prescription for children to suppress panic.
