My sister-in-law had high blood pressure during her pregnancy and was diagnosed with pre-eclampsia (high blood pressure during and just after pregnancy). 4 days after the birth of her baby, she had to be warded in ICU where she was injected with MgSO4 to lower her blood pressure. I was thus particularly interested in the uses of MgSO4 when I came across it while teaching Group II, and found out that besides being used as a laxative, it is also useful to lower blood pressure and increase the intake of calcium in the body. This knowledge has influenced me to eat more green vegetables as they are a rich source of both calcium and magnesium. (thus making green vegetables a better source of calcium than milk!) And since MgSO4 can diffuse through the skin, bath salts contain this ingredient to improve health and beauty. Problems with your digestive system and feeling edgy before falling asleep at night? Take a warm bath with epsom salt. Check out http://www.epsomsaltcouncil.org/ to read more about its many uses.
