you think it would be ok to use epsom salts in place of sea salt?
Absolutely. I posted a study on the previous page in which they used Dead sea salt which has a high magnesium content, and epsom salt is magnesium sulfide, which is a compound of magnesium, sulfur, and oxygen. The sulfur in it has antibacterial, anti-fungal, and anti viral properties. So for sure, i'd say that is a great alternative, and it should have been one that I put in the original post
what do you think about not keeping it in the fridge? I'm going to be travelling and don't know how to store it.
