Salt usage for wound treatment has been started since the Egypt age. Papyrus paper writing about prescription of salt usage that dissolve in a water, honey,or special oil to drain a wound,and healing a dermatofitosis /fungi infection. Hippocrates (460 AD) from Greece, Dekundres (100M) from Roman,Galileo from Greece (129AD- 200AD),Ibnu Sina from Arab had a prescriptions about salt treatment for a wound.
When the salt mixed with a water, especially warm water wil form a particle with different electrical load, Natrium ion that has a positive electrical load and chlor that has a negative electrical load. When the salt solution giving to wounded part,these ion will control the compression of the cells around the wound. The compression is controlled such a way till the liquid will not go out from the cell. With the other words,the wound will be dry faster. salt solution not only dry up the wound, but also killed the bacteria which attacked the wound (especially staphylococcus and streptococcus). About 4 years ago, Prof. Yen Con Hung from University of Georgia found that salt solution that conducted by electrical current evidently kill more bacteria especially a bacteria that stick on plants or cutting board.
