I note with interest under "Medical Supplies" on this list that Iron Rust is listed as an allowed medical item. My father, who was born in 1892, told us that his mother used to put nails, etc. in water and allow them to rust, then in spring she took out the metal, poured off most of the water and gave them the settlings in a spoon as their iron tonic for spring. I took this with a grain of salt because I didn't think anyone could survive such a treatment. Could it be that it was used that way and this is what the Iron Rust was for? Any ideas? L.Bell
