The salt of the sea meets the fire of high heat and is born as a new material which is useful for human beings. This bamboo salt is called the forbidden sea.

Bamboo salt is an invention of Dr. Insan. The western sea solar salt is minced after getting rid of bittern into the blue king bamboo shoot (木) from the southern coast of Jirisan, putting them into iron kiln (金) after closing the inlet with red clay (土) from the deep in Jirisan without manure, refining them eight times with pine tree wood fire (火), then smelting with high heat using resin for the 9^th time to be completed. The genuine bamboo salt is a bamboo salt that is completed by the principle of the five elements and 9-times high heat process which Dr. Insan founded for bamboo salt applying the Five Elements theory and 九轉金丹 theory. The salt of the sea meets the fire of high heat and is born as a new material which is useful for human beings, that we call the genuine bamboo salt the divine medicine from the sea.
