Magnesia phosphorica, sometimes called Mag phos, is a homeopathic remedy prepared using the salt magnesium phosphate.
According to homeopathic practitioners, this remedy has many medical uses for a wide variety of health problems, including various types of pain, muscle tension, indigestion, and fatigue. It is often used specifically as an anti-spasmodic remedy and to treat conditions that involve cramping and neuralgic pain, or nerve pain, such as headaches and abdominal cramps.
In homeopathy, Magnesia phosphorica is a well-known and commonly prescribed remedy for a wide range of health problems. It is used as a sleep aid, to help relaxation, and to treat coughs and colic. It is primarily used for pain relief, however, and may be prescribed to relieve the pain associated with teething, ear infections, and menstruation, as well as muscle pains, toothaches, and headaches.
Similar to other homeopathic remedies, Mag phos is available in various potencies. The potency of a homeopathic remedy does not depend on how much of an active ingredient it contains, but instead on how much the active ingredient has been diluted with water or alcohol, and on how many times the preparation has been vigorously shaken, a procedure known as succussion. Dilution and succussion are thought to activate the medical properties of the ingredients and increase the potency of the remedy. Homeopathic practitioners also believe that the medical effects of a remedy vary depending on its dilution, and how many times it has been shaken.
According to the National Digestive Diseases Information Clearinghouse, diarrhea is one of the possible side effects of magnesium phosphate. During hyperacidity or when the stomach produces excessive amounts of gastric acid, indigestion might occur. The stomach empties at a significantly slower rate, delaying the transport of food to the small intestines. In this situation, antacids are taken to neutralize the acid in the stomach and decrease gastric acid production. Among the common antacids used is magnesium. Aside from neutralizing gastric acid, magnesium phosphate also has a laxative effect, which may lead to diarrhea. Magnesium supplements and magnesium-based products are to be used cautiously to minimize side effects.
Vomiting is among the possible side effects of taking magnesium phosphate, as noted by MedlinePlus. Vomiting may be a symptom of several underlying conditions. Pregnant patients and those suffering from motion sickness may throw up. Substances that can irritate the stomach include food, drugs and supplements. Magnesium phosphate may irritate the gastrointestinal tract. When taken in adequate amounts, magnesium is absorbed in the small intestines and excreted through the kidneys.
