Mag phos, or Magnesia phosphorica, is a homeopathic remedy known as “the homeopathic aspirin” for its pain-relieving, antispasmodic effects. It is a favorite among homeopaths and moms aiming for a drug-free lifestyle, thanks to its gentle yet effective touch. Let’s explore why Mag phos should be in every natural remedy kit! If your heart beats for raising healthy, natural kids, this remedy may just become your new best friend.

The Folklore and History of Mag Phos
Magnesia phosphorica, found in the earth’s crust, sparked homeopathic curiosity in the 19th century. Practitioners observed its soothing effects on nerve pain and muscle spasms. Additionally, folk stories tell of wise women using it for childbirth pains and the grueling cramps of manual labor. As a result, Mag phos became a trusted staple in medical kits long before drugstore painkillers took center stage.
It is a cell (or tissue) salt and key homeopathic remedy introduced by Dr. Wilhelm Schüßler in the 19th century. As a combination of magnesium and phosphoric acid, it represents the union of two vital minerals with long historical use.
Joseph Black first isolated magnesium in 1754, deriving it from magnesia alba, a substance named after the mineral-rich region of Magnesia in Greece. In 1669, Hennig Brand isolated phosphorus. The homeopathic remedy is prepared by combining magnesium sulfate (Epsom salt) and sodium phosphate in solution. This produces the magnesium phosphate salt, often in the form MgHPO₄, a white crystalline powder. For homeopathic use, this substance is triturated (ground with lactose) and then diluted according to standard homeopathic methods. This sequence—dilution and succussion—is critical to the production of all homeopathic remedies, ensuring their safety and gentle action.

How to Use Mag Phos
