I’ve always been a big fan of the benefits of Epsom Salts (Magnesium Sulphate) and the importance of Magnesium for our cells.
Wikipedia does a good job at summarizing the importance of Magnesium at http://en.wikipedia.org/wiki/Magnesium_in_biology
As a Physical Therapist, I was interested in it from the stand point of it’s effect on the muscles. The way that muscles contract is that they bring calcium into the cell allowing the muscle to contract. The job of Magnesium is to pull the calcium out of the cell, allowing the muscle to relax and recover. Without sufficient Magnesium in the area, the muscles will remain in a contracted state. The irony with tight muscles is that they tend to not receive much oxygenated blood (with dietary Magnesium) very well and Magnesium travelling transdermally may be a kind of back door way to get to muscle tissue. People ask me if dietary Magnesium is sufficient. I believe that good food is helpful but supplements may not absorb so well.
The additional benefits of Magnesium can also serve Nervous System cells, cardiac and smooth muscle cells like of the Digestive system and of the arteries. There is strong proof of the benefits of Magnesium for Arrhythmia, lowering blood pressure by reducing contraction of blood vessels and improvement of contraction of the large and small intestines as it moves food through our system. The digestive system works best with enzyme release and food movement when the body is in relaxation state as well.
It may also be beneficial for the effects of the Nervous System over-firing and things like panic attacks, chronic stress, insomnia and even Fibromyalgia.
I’m always a believer though that it is never just one thing ie: Have an epsom salt bath and everything’s ok. Lifestyle change, habit changes and other things also need to be present for a healthy body to operate. I also believe that if it doesn’t hurt to try, then it’s worth doing.
Check with your doctor if you have concerns. They may not back it up, but it it’s okay to try, then give it a shot for sure. I generally have 1 or 2 Epsom Salt baths per week with 2 cups of salts per bath for 15 minutes with the water at comfortable temperature.
