Epsom salt (magnesium sulfate) isn't salt — it's a mineral. The Amish buy it in bulk.
Bath
2 cups per full bath. 20 minutes. Magnesium absorbs through skin — relaxes muscles, relieves pain. After a hard work day — best recovery.
Compress
Dissolve in warm water, soak cloth, apply to bruise or sprain. 15-20 minutes. Reduces swelling.
Splinters
Soak finger in strong solution (3 tbsp per cup) 15 min. Skin softens, splinter comes out easier.
In the Garden
1 tbsp per hole when planting tomatoes and peppers. Magnesium needed for photosynthesis. Yellow leaves between veins = magnesium deficiency = Epsom salt fixes it.
Cost
10 kg bag — $10-15. Lasts half a year of baths and entire garden season.
