Bamboo Salt (also known as Jukyeom) originates from Korea. It was originally developed by Korean doctors and monks almost 1,000 years ago as a folk medicinal remedy for various illnesses. The Bamboo Salt is made by putting sea salt into cases made from bamboo trunks with 3 years of growth. After the salt is inserted into the trunks, the ends are sealed with natural yellow clay that is rich in minerals. The trunks are then roasted in a furnace with pinewood being used as fuel. The process requires 10 hours of roasting at a temperature between 1,000 to 1,500 oC. This procedure can be repeated from three to nine times. In the ancient times, the process was only repeated two or three times. However, through repeated experimentation that doctors discovered that Bamboo Salt gained higher medical effectiveness if it was baked for more time. This method enhanced the amalgamation of minerals from the bamboo and the yellow clay into the sea salt.
