As the seed of oak, acorn symbolizes potential and patience. In Nordic and Celtic cultures, acorns symbolize life, fertility and immortality. This lovely fruit is also regarded as a symbol of luck, prosperity, youth and strength. Its special shape is also very popular with designers and often appears in jewelry and works of art.

Because acorn contains a lot of starch, it was once one of the earliest staple foods of mankind. It can be clearly seen that this plant also played an important role in people's life at that time. Acorn has another characteristic, which some people don't like very much, because its fruit composition contains something called tannin, and the tannin taste is sour, not easy to digest, and also contains small poison. Therefore, later, with the changes of the times, human beings began to tend to grain, and gradually this acorn was replaced by grain.
