No. 7 – the Schüssler salt for nerves and muscles, renowned for its rapid cramp relief and relaxing effects.
Interesting facts about Magnesium phosphoricum
- Ceramic raw material – high heat resistance.
- Can be used as a laxative at higher doses.
- In the food industry as an anti-caking agent, acidity regulator, and flame retardant.
Effects & Properties
Magnesium regulates the electrical-neural signal transmission – It dampens the "nerve fire" at the motor end plate. In this way, it regulates muscle tone in both voluntary and involuntary muscles. Without enough magnesium, nerves fire too easily and too often—leading to cramps.
Features: relaxing, antispasmodic, regulating, stabilizing, soothing to the nerves.
Storage Locations & Deficiency Symptoms
Stored in the liver, blood, and muscles. Symptoms of deficiency:
- Muscle cramps, muscle stiffness, colicky abdominal pain
- Restlessness, sleep disturbances, stress, dry cough
- Headaches, asthma, cravings for sweets
Applications
Magnesium phosphoricum for trigeminal neuralgia
Trigeminal neuralgia is caused by hypersensitivity of the trigeminal nerve—even minor stimuli (chewing, speaking, or a draft) can trigger severe pain attacks. Magnesium phosphoricum directly regulates nerve impulses: it dampens the electrical activity of the hypersensitive nerve, reduces hypersensitivity, and makes pain attacks less frequent and less severe.
Magnesium phosphate for menstrual cramps
Menstrual cramps are caused by excessive contractions of the uterine muscles—the uterine nerve sends out overly intense contraction signals. Magnesium phosphoricum relaxes the cramping uterine muscles directly at the neuromuscular junction. The classic method of use: 7 tablets in hot water in the evening before bedtime—the hot water speeds up absorption.
Magnesium phosphoricum for sciatica and back pain
Sciatic pain occurs when the irritated sciatic nerve causes the surrounding muscles to go into a sustained spasm—the spasm presses on the nerve and intensifies the pain. Magnesium phosphoricum regulates muscle tension directly at the source (the neuromuscular junction): muscle tension decreases, pressure on the nerve eases, and the pain subsides.
Magnesium phosphate for constipation
Nervous constipation occurs when the smooth muscles of the intestine spasm due to excessive nerve signals—causing peristalsis to come to a halt. Magnesium phosphoricum relaxes the intestinal muscles by dampening these excessive nerve signals. Peristalsis resumes, and bowel movements become possible again.
Instructions for Use
Hot 7: Dissolve 10 tablets in hot water—traditionally taken in the evening. Alternatively, take during the day to boost stress resilience.
Pregnancy & Breastfeeding
No need to worry—overdose is highly unlikely due to increased consumption during pregnancy.
