I have found that Epsom Salt works nicely for bumps, bruises, and muscle soreness.
But Epsom Salt (magnesium sulfate) is not the form the body best recognizes. Magnesium chloride is better recognized, utilized, and retained in the body, and works much faster. This is especially critical during times of extreme depletion, or for example, in emergency medicine. Magnesium sulfate, moreover, is known to present greater issues with toxicity. It is best used in cases such as autism, where sulfur is required.
Magnesium chloride also provides additional benefits for detoxification. For example, the chloride form competes for uptake with the toxic halides (chlorine, fluoride, and bromine). When these poisons are prevented from reaching high levels, the body can better assimilate iodine, which is needed for metabolic health, and for producing energy (ATP). Magnesium chloride thereby provides multiple benefits, acting synergistically to build optimal health.
I know a woman who was severely debilitated with a mystery disease. Her muscles were so tight, her chiropractor said she had the tightest muscles he'd ever seen. Her doctors were mystified, but that did not stop them from offering her plenty of drugs and surgery options (all of which failed!).
She then started using magnesium oil (magnesium chloride), applying it directly on her skin. In less than a month, she had more energy than she had in thirty years. She walks easily now. She is considering taking herself off disability, and going back to work. Her recovery seems miraculous. Her so-called disease was an extreme magnesium deficiency. Given that most Americans are deficient in magnesium, magnesium chloride can benefit nearly everyone.
For individuals with heart conditions, magnesium chloride offers rapid relief for potentially deadly episodes. Even hospitals know about magnesium chloride. Hospitals inject it intravenously into heart patients (which is expensive and painful). When used transdermally at home, it is neither expensive, nor painful. In fact, it is simple, easy, and convenient to use.
Dr. Mark Sircus discusses the relative value of magnesium chloride versus magnesium sulfate. He devotes an entire chapter to this topic in Transdermal Magnesium Therapy (2007). He states clearly that magnesium chloride is the transdermal magnesium of choice for individuals interested in optimal health. He explains in detail why magnesium chloride is best recognized, assimilated, and utilized in the body. I highly recommend his book, but you don't need to read it in order to gain the benefits of magnesium chloride.
Magnesium oil (magnesium chloride) is available in several types. One is ultra-pure Ancient Minerals Magnesium Oil, which is sourced from ancient seabeds lying deep underground for millions of years. Another type is Ocean Minerals Magnesium Oil, which derives from purified seawater. Both types work. They are available from doctors, naturopaths, and online from Integrated Health:
I would never say not to use epsom salt. I still use it myself. In the larger picture, magnesium chloride (magnesium oil) will provide the greatest benefits for most people, and especially for individuals who require immediate repletion, or who cannot afford to wait to increase their magnesium levels. Lives may depend on it. Even those who are not in dire deficiency will notice its effectiveness. A single day not spent in the hospital can pay for a lifetime supply of magnesium oil, which will contribute to a longer, healthier life.
