The Process of Bamboo Salt ( text on pic are in Malay only)

What is the difference between Bamboo Salt and regular salt?
The natural ingredient of Bamboo Salt is 100% organic sun-dried salt made of energy seawater generated by the vast underground ore cluster at Yeonpyeong Island and Hyeongjun Peninsular, West Coast of Korea. The natural salt is poured into a 3-year old bamboo tube and sealed by unpolluted yellow clay. Sealed bamboo tube will be incinerated in kiln with pine firewood to melt and harden the natural salt into a column. While processing, not only harmful substances (such as heavy metals and chemical substances) have been removed but the nutritional value has also been enriched.
Most regular (chemical) salt contains 99% sodium chloride (NaCl) and acid which harm human body if taken for long term.  Bamboo Salt is rich withmagnesium that helps the absorption of calcium and maintains fluid balance, essential for contraction of muscle, control high blood pressure and strengthens the memory.
