In culture In Korea, it is called ssuk () or tarae ssuk () which is deeply related to the mythical figure of Tan'gun (). According to the Samguk yusa, Tan'gun established Gojoseon in 2333 BCE. He was said to be born from the union of the Ungnyeo ('bear-woman') with Hwanung, son of Haneunim, god of the heavens. While Tan'gun is a mythological figure,"An extreme manifestation of nationalism and the family cult was the revival of interest in Tangun, the mythical founder of the first Korean state... Most textbooks and professional historians, however, treat him as a myth."

"Although Kija may have truly existed as a historical figure, Tangun is more problematical."

"Most [Korean historians] treat the [Tangun] myth as a later creation."

"The Tangun myth became more popular with groups that wanted Korea to be independent; the Kija myth was more useful to those who wanted to show that Korea had a strong affinity to China."

"If a choice is to be made between them, one is faced with the fact that the Tangun, with his supernatural origin, is more clearly a mythological figure than Kija." some interpret his legend as a reflection of the sociocultural conditions of the kingdom's early development.

To ancient inhabitants of Korea, ssuk was one of the foods believed to have medicinal or religious value. The Ungnyeo transformed herself from a bear into a woman by eating nothing but twenty cloves of garlic and a bundle of ssuk for 100 days.
