This year starting February 4 2012 to February 4 2013 the sickness star is in the North sector , please place coin salt water cure there, another place to put coin salt water cure is SouthEast since 5 yellow is in that sector. You can place salt water cure in bad water and mountain stars as well, for example based on the period of your house and based on the facing direction North 1 or North 2/3 mountain and water stars are different sectors, please provide more detail information. You can place your salt water cure anywhere in above specified direction , have to make sure that the cure is exposed to air and not inside of cabinets, you can put them behind items out of sight so that you don't walk into it or knocked down accidentally and make sure you don't spill it because of bad energy accumulated in the cure, you have to put something under the cure to protect the floor or you furniture, since when the cure gets exposed to bad energy it expands and grows out of the container that is in.
Please provide additional information to further assist you.
Period of your house
More detail facing direction N1 or N2/3
Take care
