Medicinal salt is a combination of sea salt and pharmaceuticals. Medicinal salt can be made by evaporating saltwater that contains pharmaceuticals from urban wastewater. Medicinal salt has not only a great natural salty taste, but can also address headaches, depression, infections, and a host of other common ailments.
It's easy to make your own medicinal salt. The process involves finding a water treatment plant, harvesting its treated water output (effluent), building simple salt evaporation ponds, and collecting the dried sea salt.
What you need:
a local water treatment plant
4 x 5 gallon buckets
wood: two 10ft 2x6"s for the length and two 6ft 2"x6" boards. We made 3 ponds, but one will suffice.
At least 35 square feet of 3mil - 6mil plastic sheet or heavy-duty pond lining (any color, but black will generate the most heat, which is good for evaporation)
staple gun and staples (3/8", 10mm)
1" wood screws
steel corner braces.
black gaffers tape
