You can place some in a container in
the fridge to get rid of odors, put some in
your shoes to get rid of nasty smells. These are just a few uses, you can also use it in baking, cleaning and all sorts.
If you get any more of those nasty lump
s, go to the doc asap for an investigation and an antibiotic if required. Magnesium sulphate can be used as a drawing ointment, but only when the skin is not broken.
