Magnesium Sulfate and Epsom Salts as a Magnesium Supplement
History of Magnesium Sulfate and Epsom Salts
In the early 1600's, a farmer at Epsom Surrey England found his cow's drinking water healed scratches and rashes. Soon, the locals started to talk and the water became known for its healing properties and it was discovered that the healing properties were due to the mineral magnesium sulfate in the water.
Named after the town, Epsom salt was prepared by boiling down the mineral waters found at the springs that arise where the non-porous London clay meets the porous chalk of the North Downs. Today Epsom Salt is obtained mostly from mining operations. Epsom salts' chemical name is magnesium sulfate and contains magnesium, sulfur and oxygen, with the formula MgSO4. Epsom salts can also have the form heptahydrate epsomite (MgSO4·7H2O).
Magnesium Sulphate used in medical research
Magnesium sulphate has been used a lot for medical research because it has been around for so long. Some of the research includes:
• Replacement therapy for hypomagnesemia.
• Magnesium sulfate is the first-line antiarrhythmic agent for torsades de pointes in cardiac arrest under the 2005 ECC guidelines and for managing quinidine-induced arrhythmias.
• As a bronchodilator, after beta-agonist and anticholinergic agents have been tried, e.g. in severe exacerbations of asthma. Recent studies have revealed that magnesium sulfate can be nebulized to reduce the symptoms of acute asthma. It is commonly administered via the intravenous route for the management of severe asthma attacks.
The main ingredient, that produced the positive effects, in all this research, is magnesium. We suggest that you supplement with a form like Magnesium Rub or Magnesium Gel for the transdermal effect. Not only do you get the great effect of magnesium transdermally, but you also get the benefit of many trace elements, as these products are from a concentrate of sea water. Another great product is Mag365 and has help thousands of people deal with their magnesium deficiency issues. No wonder it is the best selling magnesium supplement.
